2013This study deals with the pitfalls and standards associated with the digitisation of photographic artefacts in formal collections. The popularity of the digital medium caused a rapid increase in the demand for converting images into digital files. The need for equipment capable of executing the task successfully, the pressure on collection managers to display their collections to the world and the demand for knowledge needed by managers and operators created pressure to perform optimally and often in great haste. As a result of the rush to create digital image files to be displayed and to be preserved, the decisions that are being made may be questionable. The best choice of file formats for longevity, setting and maintaining standards to guarantee quality digital files and consultation with experts in the field of digitisation as well as attention to best practices are important aspects which must be considered. In order to determine the state of affairs in countries with an advanced knowledge and experience in the field of digitisation, a comprehensive literature study was done. It was found that enough information exists to enable collection managers in South Africa to make well informed decisions to ensure a high quality of digital collection. By means of questionnaires, a survey was undertaken amongst selected Western Cape image preservation institutions to determine the level of knowledge of the managers who are required to make informed decisions. The questionnaire was designed to give insight into choices being made regarding the technical quality, workflow and best practice aspects of digitisation. Comparing the outcome of the questionnaires with best practices and recommended standards in countries with an advanced level of experience it was found that not enough of this experience and knowledge is used by local collection managers although readily available. In some cases standards are disregarded completely. The study also investigated by means of questionnaires the perception of the digital preservation of image files by fulltime photographic students and volunteer members of the Photographic Society of South Africa. It was found that uncertainty exist within both groups with regard to file longevity and access to files in five to ten year's time. Digitisation standards are set and maintained by the use of specially designed targets which enable digitising managers to maintain control over the quality of the digital content as well as monitoring of equipment performance. The use of these targets to set standards were investigated and found to be an accurate and easy method of maintaining control over the standard and quality of digital files. Suppliers of digitising equipment very often market their equipment as being of a high quality and being able to fulfil the required digitisation tasks. Testing selected digitising equipment by means of specially designed targets proved however that potential buyers of equipment in the high cost range should be very cautious about suppliers' claims without proof of performance. Using targets to verify performance should be a routine check before any purchase. The study concludes with recommendations of implementing standards and it points to potential future research.

Full textAbstract:
This thesis explores the contemporary genre of popular digital photography, with a specific look at photographs taken in/of Iran. It focuses on the contemporary practice of 'photoblogging' or photography-based weblogging. Photoblogs are the result of the daily posting of digital photographs concerning everyday life in Iran on personal blogs specifically dedicated to photography. The title of the thesis, Camera Iranica, refers to the subject and scope of the study, as well as to its digital-ethnographic field site. I demarcate this as a conceptual and transnational cultural field, encompassing the multitude of places and spaces, on- and offline in which Iranians across the world engage in the practice of producing and viewing popular digital photography. Iranian photoblogs are shown to operate in a manner contingent upon a particular 'visual legacy' of contested cultural identity politics since the Islamic Revolution of 1979, propagated inside Iran and in 'the West'. The thesis traces the social, economic and political implications of developments in photography and digital technologies in Iran in light of this backdrop, and explores how and why Iranians in Iran and abroad are taking up popular digital photography for visual storytelling projects, with 'Iran' as their visual subject. Based on the study's empirical findings, I extrapolate theoretical arguments concerning historical and cultural understandings of digital photographs shown and seen in online environments, and propose innovative methodological strategies for digital-visual anthropologists to continue work in these fields.

Full textAbstract:
An abstract of the thesis of Ben Huang for the Master of Science in Electric and Computer Science presented [August 12nd, 2010]. Title: Removing textured artifacts from digital photos by using spatial frequency filtering Virtually all image processing is now done with digital images. These images, captured with digital cameras, can be readily processed with various types of editing software to serve a multitude of personal and commercial purposes. But not all images are directly captured and even of those that are directly captured many are not of sufficiently high quality. Digital images are also acquired by scanning old paper images. The result is often a digital image of poor quality. Textured artifacts on some old paper pictures were designed to help protect pictures from discoloration. However, after scanning, these textured artifacts exhibit annoying textured noise in the digital image, highly degrading the visual definition of images on electronic screens. This kind of image noise is academically called global periodic noise. It is in a spurious and repetitive pattern that exists consistently throughout the image. There does not appear to be any commercial graphic software with a tool box to directly resolve this global periodic noise. Even Photoshop, considered to be the most powerful and authoritative graphic software, does not have an effective function to reduce textured noise. This thesis addresses this problem by proposing the use of an alternative graphic filter to what is currently available. To achieve the best image quality in photographic editing, spatial frequency domain filtering is utilized instead of spatial domain filtering. In frequency domain images, the consistent periodicity of the textured noise leads to well defined spikes in the frequency transform of the noisy image. When the noise spikes are at a sufficient distance from the image spectrum, they can be removed by reducing their frequency amplitudes. The filtered spectrum may then yield a noise reduced image through inverse frequency transforming. This thesis proposes a method to reduce periodic noise in the spatial frequency domain; summarizes the difference between DFT and DCT, FFT and fast DCT in image processing applications; uses fast DCT as the frequency transform to solve the problem in order to improve both computational load and filtered image quality; and develops software that can be implemented as a plug in for large graphic software to remove textured artifacts from digital images.

Full textAbstract:
Colour images can be formed by the combination of stimuli in three primary colours. As a result, digital colour images are typically represented as a triplet of values, each value corresponding to the stimulus of a primary colour. The precise stimulus that the eye receives as a result of any particular triplet of values depends on the display device or medium used. Photographic film is one such medium for the display of colour images.
This work implements a software system to calibrate the response given to a triplet of values by an arbitrary combination of film recorder and film, in terms of a measurable film property. The implemented system determines the inverse of the film process numerically. It is applied to calibrate the Optronics C-4500 colour film writer of the UBC Laboratory for Computational Vision. Experimental results are described and compared in order to estimate the expected accuracy that can be obtained with this device using commercially available film processing.Science, Faculty of

Full textAbstract:
Contemporary digital imaging practice has largely adopted the visual characteristics of its closest mediatic relative, the analogue photograph, In this regard, new media theorist Lev Manovich observes that "Computer software does not produce such images by default. The paradox of digital visual culture is that although all imaging is becoming computer-based, the dominance of photographic and cinematic imagery is becoming even stronger. But rather than being a direct, "natural" result of photo and film technology, these images are constructed on computers" (Manovich 2001: 179), Manovich articulates the disjuncture between the technical processes involved in the digital image creation process and the visual characteristics of the final digital image with its replication of the visual qualities of the analogue photograph. This research addresses this notion further by exploring the following. What are the defining technical features of these computer-based imaging processes? Could these technical features be used as a basis in developing an alternative aesthetic for the digital image? Why is there a reticence to visually acknowledge these technical features in contemporary digital imaging practice? Are there historic mediated precedents where the inherent technical features of the medium are visually acknowledged in the production of imagery? If these defining technical features of the digital imaging process were visually acknowledged in this image creation process, what would be the outcome? The studio practice component of the research served as a foundation for the author's artistic and aesthetic development where the intent was to investigate and highlight four technical qualities of the digital image identified through the case studies of three digital artists, and other secondary sources, These technical qualities include: the composite RGB colour system of the digital image as it appears on screen; the pixellated microstructure of the digital image; the luminosity of the digital image as it appears on a computer monitor, and the underlying numeric and (ASCII based) alphanumeric codes of the image file which enables that most defining feature of the image file, that of programmability, Based on research in the visualization of these numeric and alphanumeric codes, digital images of bacteria produced through the use of the scanning electron microscope, were chosen as image content for an experimental body of work to draw the conceptual link between these numeric and alphanumeric codes of the image file and the coded genetic sequence of an individual bacterial entity.

We have introduced a geometry which is invariant to certain forms of burning and dodging photographic prints. We then used this geometry to create invariant measurements which represent information which would not change given different photographic printing processes.The presented algorithm used properties of best-fit planes to represent a photograph. There are many other possibilities for measurements which would fit this framework. Further, the representation of photographs presented in this thesis could be combined with existing computer vision algorithms for such tasks as object recognition within photographs for which we do not know the development process.

Full textAbstract:
South African photojournalists’ perception of digital technology’s impact on the credibility of news photographs is investigated in this study. Digital technology has the capabilities to produce “manipulated” photographs that appear realistic and credible. Credibility is dependent on a variety of factors including codes of realism and codes of production, which fit conventional codes of photographic representation. Manipulation is the act of deviating from accepted codes of photographic representation that may jeopardise the credibility of news photography. This thesis proposes a new theoretical framework that encompasses existing theories of semiotics, ideology, naturalism, realism and credibility. These theories underpin the definitions and discussion on manipulation and credibility. A descriptive survey is used which attempts to discover photojournalists’ views towards credibility. This research draws on qualitative research methods using a largely qualitative questionnaire, which generates both qualitative and quantitative data. The questions are formulated around two case studies of digitally manipulated photographs. The trends and responses in the research data are connected and discussed. The findings of this study are discussed in terms of credibility, awareness of the digital changes, the reason for the changes, the role of a caption, deletion techniques and background changes. The empirical situation is analysed in relation to the theoretical discussions and this study’s theorisation of photographic representation.

Full textAbstract:
More and more it is becoming increasingly difficult to discern photo reality from digital reality. Digital imagery is revolutionising photography and challenging preconceived notions of this art form. Over the years, photography has been viewed metaphorically as a window on the world and on the past. No longer however, is the creation of photographic imagery reliant upon its intrinsic relationship with reality. Using computer technology original photographic material can be altered, manipulated and seamlessly combined with other fictional imagery without obvious detection and with relative ease. The proliferation of digital imaging is producing two apparent crises for photography. The first is the perceived threat to photography, involving the fear that traditional photographic processes, methods and product will be superseded by manipulated digital images passing themselves off as real photographs. Added to these growing concerns for photography's longevity, is the prospect that viewers will no longer believe m photography as a deliverer of objective truth and that the medium itself will lose its power as a 'privileged conveyer of information'(Batchen, 1994,p.47). The second crisis pertains to ethical concerns that these digital simulations raise: copyright, moral rights and artistic integrity.

2013This study investigates the perspective of Capetonian professional photographers on issues of integrity, regarding the impact of digital imaging technology. Key objectives are to establish how the concept of photographic integrity manifests itself throughout the history of the documentary genre, prior and subsequent to the introduction of digital imaging technology; to ascertain the extent to which the Capetonian professional photographer uses digital imaging technology compared to film technology; to discover how Capetonian professional photographers perceive various concepts related to integrity in a documentary photograph; to identify what Capetonian professional photographers regard as acceptable digital editing to the photojournalistic documentary photograph; to ascertain whether Capetonian professional photographers believe that digital imaging technology impacted on the integrity of the documentary photograph; and finally, to discern whether Capetonian professional photographers who have practiced professional photojournalism see the need for a national regulating body, which clearly makes known what acceptable picture taking (in terms of content, e.g. staging of a photograph) and digital editing entails, for the South African photojournalist. The rationale for this study is that we exist in an era where we are faced with a digital revolution which transforms perceptions of integrity and it is essential to ascertain how technology influences the perceptions of the very professionals who produce documentary photography images. The literature review evolves a context for this study. This empirical study’s data collection and analyses has a mixed-method design. The survey’s instrument of data collection is a questionnaire, which captured quantitative data and with half of one question captures qualitative data. I analysed quantitative data with the help of SPSS and I analysed qualitative data much akin to a case study. The statistical test used to analyse quantitative data is a chi-square test and there are 66 participants in the study. I found that a breach of integrity, for instance manipulation, was always possible in the era prior to the introduction of digital imaging technology. Now it is only done faster, more thorough and more people have access to editing technology. Many who lack moral fiber are tempted now, more than ever, to illicitly manipulate. Capetonian professional photographer’s experience in digital image creation and editing technology outweighs the equivalent in the film medium. Digital camera usage takes precedence over film cameras. An example of a perception of a concept related to integrity in documentary photography is the sub-group which has practiced professional photojournalism insisted (73.5% of them strongly agreed) that it is possible to be creative and truthful at the same time in documentary photography. With regard to what acceptable editing entails, for cropping respondents favoured slight cropping; for dodging and burning in respondents favoured very light dodging and burning in; for pasting in respondents favoured no pasting in is acceptable; and for removing of objects respondents favoured no removing of objects. The Capetonian professional photographer believes that digital imaging technology has impacted on the integrity of the documentary photograph. For instance, the study has measured and proved that a majority of Capetonian professional photographers believe that a documentary essay taken in film and processed in the traditional darkroom feels more consistently trustworthy than its digital equivalent. This study has shown that there is a need for a body that clearly makes known what acceptable picture taking and digital editing entails for the professional photojournalistic photographer in South Africa.

This study explores the differences in attitude held by newspaper photographers and designers concerning the acceptability of digitally altering front-page photographs. It takes its findings from a summer 2006 survey that asked these two newsroom groups to rate their acceptance of certain common techniques used to change photographs from their original forms. Their answers revealed that designers are generally more accepting of altered photographs than their photographer colleagues. Also, photographers are more likely to find acceptable those photographs altered for technical reasons than for aesthetic ones. Least acceptable to photographers, this study finds, are alterations that affect a photograph's content.Department of Journalism

The first type is based on space domain operations and has been discussed in the literature. The second type, to be introduced, is based on the intuitive concept that the spectral energy distribution of a focused object is biased towards lower frequencies after blurring. This approach requires digital image filtering in the spatial frequency domain. A comparison among methods of both types is made using a quantitative uÌ delity criterion.

Full textAbstract:
Digital technology has now become pervasive at most publications in South Africa and in America. Pictures are routinely digitised by publications for ease of handling in the layout process, and this makes it relatively easy to alter or manipulate the pictures using computer software programmes. This thesis attempts to gauge the views of South African photojournalists about the digital manipulation of news photographs, and compare these to the views of American photojournalists. It is based on the hypothesis that South African and American photojournalists have different views of what is acceptable manipulation of news photographs, and that their reasons for this will also be different. This thesis also suggests that the manipulation of news photographs is ethically problematic and can damage the credibility of both the photojournalist and the publication in which the photographs appear. The study involves a comparison of the results from a questionnaire given to South African photojournalists and a similar questionnaire given to American photojournalists. The questionnaires were then supplemented by interviews with six South African photojournalists. The thesis then draws conclusions from the responses to the questionnaires and interviews. These conclusions partially support the initial hypothesis, in that there are some differences between the views of South African and American photojournalists, but, on the whole, these are remarkably similar. Photojournalists do seem to find the manipulation of news photographs to be ethically problematic, but they may find the manipulation of other kinds of images (eg fashion or soft news) to be acceptable. South African photographers also find the manipulation of images by other means (eg different lenses or darkroom techniques) to be more acceptable than Americans do. Although the underlying reasons for these views may differ, maintaining the credibility of the photographer and the publication does seem to be the major issue for avoiding digital manipulation. South African photographers seemed to think that if the photographer had done his or her job well, there would be no need for manipulation, and both groups (but especially the Americans) felt that manipulation could often be equated to lying to the reader, and that this might damage their reputation, and that of their publications.

Full textAbstract:
Photojournalism in South Africa is in the process of undergoing a shift from an analogue past to a fully digital future. This shift to digital has already been completed by many of the newspapers in the United States of America and Europe, and the new technology is seen to have made fundamental differences in the way that journalists do their job. This thesis attempts to explore the differences brought about, as well as the problems experienced by the photographic department at the Sowetan newspaper as a result of the shift to digital. How the development of technology has affected the photojournalist throughout is focused upon in a brief history of photojournalism and examples of how technology has shaped different aspects of journalism in both a positive and negative manner is considered. Exactly what digital photography is, how it has been integrated into American Photographic departments and the changes that the new technology has prompted are also explained. The manipulation of images in the past as well as the relative ease of digital manipulation are covered and concerns are raised about the future implications of digital manipulation. By conductlng participant observation and holding interviews, research data was compiled which allowed conclusions to be drawn about the impact that the shift to digital had had on the Sowetan photographic department. Intentional and unintentional consequences were expected and revealed in the research. The job of the photojournalist and photographic editor was found to have changed but perhaps not as dramatically as expected. Third world factors such as crime, poverty and lack of education were discovered to have resulted in problems that differed noticeably from those experienced by American and European photographic departments. Some expected difficulties were not experienced at all, while other major obstacles, specifically the repairs that must constantly be made to the digital cameras, continue to hamper the operations of the new digital department. Some understanding of the problems that might be encountered by future photojournalism departments that are considering making the shift to digital are arrived at, in the hope that they may be foreseen and overcome.

As an artist Leah King-Smith has worked for several years in the creative medium of photography exploring notions of multidimensional states of consciousness particularly in reference to the psychic work of Jane Roberts. In this thesis King-Smith presents her creative developments as a technological shift from analogue to digital imaging, and continues, in her Research Project, to follow the same threads of investigation into the use of multi-layering as symbol and expression of simultaneous time. The thesis is two-fold in approach where in the first section, processes, contexts and concepts are presented and in the second section the themes and analysis of the final works are expressed through a creative writing style. The dichotomous method of interpretation in these two sections embodies
the antithetical relationship artists experience between reflexive analysis and creative practice as methods of knowledge.

Full textAbstract:
La pensée de Vilém Flusser (1920-1991) a donné lieu à une abondante bibliographie critique sur ses apports en matière de communication, où son pari d’une « nouvelle imagination » fait tenir ensemble l’art, la science et la technologie, sous l’égide de sa philosophie de la photographie. L’archéologie de sa pensée, proposée ici, a été construite en tenant compte de l’ancrage disciplinaire de ses travaux dans les théories de la communication et des médias : elle s’est intéressée à la notion de l’art que Flusser développe au cours de son parcours, afin de saisir le déploiement de cette dimension artistique, son statut et ses contours, aussi bien que sa portée. La notion d’art chez Flusser est indissociablement liée à l’histoire : l’expérience traumatisante de l’exil est devenue centrale dans sa pensée critique de tout totalitarisme. L’ensemble de pratiques et de savoirs qui fondent son rapport au monde et qui informent sur l’élaboration de sa pensée sont travaillés par une Kulturgeschichte, vue depuis la perspective d’une « post-histoire ». Mais il y a en particulier une pensée du jeu, ludique, où l’objectif est moins de jouer à l’intérieur des règles établies que de déjouer les règles, de « jouer pour changer le jeu ». Autrement dit, il s’agit d’une pensée radicalement dialogique et polyphonique, dont la Kommunikologie, façonnée comme métathéorie, représente l’essor de Flusser. Sa trajectoire historique et les savoirs qui lui sont associés contribuent à la construction d’une pensée cybernétique qui projette les lignes fondamentales d’une Kunstwissenschaft, dans laquelle il propose une sorte d’iconoclasme sans renoncer aux imagesThe thought of Vilém Flusser (1920-1991) has given rise to an abundant critical bibliography on his contributions in the field of communication, where his wager on a "new imagination" brings together art, science and technology, under the aegis of his philosophy of photography. The archaeology of his thought, proposed here, is constructed alongside this disciplinary underpinning of his work in the theories of communication and media: it involves the notion of art that Flusser developed during his career, in order to grasp the deployment of this artistic dimension, its status and its contours, in his thought. Flusser's notion of art is inseparably linked to history: the traumatic experience of exile becames central in his critical thinking regarding all totalitarianism. The practices and knowledge that underpin his relationship to the world and guide the development of his conception are worked on by a Kulturgeschichte, seen from the perspective of a "post-history". But there is, in particular, a playful thinking of the game, where the objective is less to play within the established rules than to thwart the rules, to "play to change the game". In other words, it is a radically dialogical and polyphonic way of thinking, whose Kommunikologie, shaped as metatheory, directs the development of Flusser's work. His historical trajectory and the knowledge associated with it contribute to the construction of a cybernetic way of thinking that sketches the fundamental lines of a Kunstwissenschaft, in which he proposes a kind of iconoclasm without giving up images

A fotografia digital e as anotações se constituem como expressão e desenvolvimento do percurso processual do trabalho realizado. As referências teóricas e visuais contaram com a Antropologia como essência, metodologia e inserção no campo de pesquisa e a Arte como espaço de reflexão e criação para o caminho poético. Diferentes questionamentos surgiram ao longo do desenvolvimento do fazer artístico e acabaram por delimitar o trabalho. Nesta pesquisa, arte, natureza e cultura tornam-se pares no processo de registro e percepção da intuição criativa fotográfica, enfatizando assim, o caráter de "work in progress". Um Livro de Fotografias e um DVD sonorizado com 170 imagens são apresentados como processo e resultado do trabalho poético
Abstract: Road, Landscape and Grass - Photographs and Reports in the Jalapão is a research in Poetic Visual consisting of travels - such as displacement and aesthetic experience - to the brazilian savannah, in the State of Tocantins/BR. The digital photography and the written summary notes are as expression and development of the proceedings of the visual work done. The theoretical and visual references counted with the Anthropology as well as essence, methodology and insertion in the field of research, and the Art to be a space for reflection and creation for the poetic way. Different questions have arisen in the course of the development of artistic making and ultimately define the work. In this research, art, nature and culture have become parts in the process of registration and perception of the creative intuition photographic, emphasizing the character of "work in progress".

L'objectif de notre recherche est d'extraire les altitudes h d'une scène donnée prise en image sous deux angles différents donnés par le satellite SPOT. Dans ce but nous avons modélisé le mouvement du satellite et de son système optique afin de transformer les deux images initiales en images épipolaires, ce qui nous permettra de réduire le temps d'appariement et de trouver les pixels homologues avec succès. Pour la mise en correspondance, nous avons utilisé une technique qui est à base de la corrélation et de la programmation dynamique. Cette méthode nous a permet d'apparier 96 % des pixels homologues avec une erreur inférieure à 5 mètres. Ce problème de mise en correspondance reste toujours ouvertThe aim of our research was to extract the level h of a precise landscape taken over two differents angles by the satellite SPOT. To do so, we have modelised the movement of the satellite and his optical system to transform the two first images in another one, epipolar which will allow us to reduce the matching time and to find with success the equivalent pixels. For the pairing, we have utilised a technic wich is based on the corrolation and of the dynamic programming. This method was very satisfactory and allow us to match 96 % of the equivalent pixels, with an error of less than 5 meters, but the original problem is still a matter of research for complimentary studing

Full textAbstract:
CNPqEste trabalho tem por objetivo apresentar uma nova proposta aos algoritmos de Demosaicing existentes, utilizando uma abordagem mais flexível quanto ao uso do Color filter array (CFA) em imagens coloridas de único sensor. O algoritmo proposto tem como base a estrutura de problemas inversos, cujo funcionamento utiliza um modelo de operação matriz-vetor que é adaptável ao CFA empregado. A partir deste conceito, o algoritmo trata o problema de Demosaicing como o de minimização de função custo, com um termo referente à dependência da estimativa com os dados obtidos e com o modelo de captura, o outro termo é relacionado aos conhecimentos observados em imagens que podem ser explorados para uma estimativa mais precisa, tal elemento é chamado de Prior. A proposta estabelecida tem como base algoritmos de regularização com foco na alta correlação presente entre os canais de cor (R, G e B), e na suavidade local de regiões uniformes, essa base formaliza o Prior empregado no trabalho. A minimização da proposta é atingida iterativamente através do IRLS-CG, que é a combinação de dois algoritmos de minimização eficientes, que apresenta rápidas respostas, e a capacidade de trabalhar com a norma L1 em conjunto com a norma L2. Com o intuito de atestar a qualidade do algoritmo proposto, foi elaborado um experimento em que o mesmo foi testado com diferentes CFAs e em situação com ruído gaussiano de 35dB e sem ruído algum em imagens da base de dados da Kodak, e os resultados comparados com algoritmos do estado-da-arte, no qual o desempenho da proposta apresentou resultados excelentes, inclusive em CFAs que destoam do padrão Bayer, que é o mais comumente usado na atualidade.
This research presents a new proposal to Demosaicing algorithms, using a more flexible approach to deal with the Color filter array (CFA) in single sensor color imaging. The proposed algorithm is structured in the inverse problems model, whose functions employ a CFA adaptive matrix-vector operational model. From this concept, the Demosaicing problem is treated as a cost function minimization with two terms, one referring to the dependence between the estimation and the data provided by the acquisition model, and other term related to features observed in images, which can be explored to form a more precise estimation, this last term is known as Prior. The established proposal is applied in regularization algorithms with focus on the high correlation among color channels (R, G, and B), and in the local smoothness of uniform regions. Both characteristics organize the Prior employed in this work. The minimization proposed is iteratively achieved through IRLS-CG, which is the combination of two efficient minimization algorithms, that presents quick responses, and the capacity to deal with L1 and L2 norm at the same time. The quality of the proposed algorithm is verified in an experiment in which varous CFA were used and a situation with 35dB gaussian noise and another one with no noise applied to the Kodak dataset, and the results were compared with state-of-the-art algorithms, in which the performance of the proposed Prior showed excellent results, including when the CFA is different from Bayer’s, which is the most commonly used pattern.

Full textAbstract:
The present thesis proposes new methods for obtaining objective and accurate diagnoses in modern healthcare. Non-invasive techniques have been used to examine or diagnose three different medical conditions, namely neuropathy among diabetics, radiotherapy induced erythema (skin redness) among breast cancer patients and diagnoses of cutaneous malignant melanoma. The techniques used were Near-InfraRed spectroscopy (NIR), Multi Frequency Bio Impedance Analysis of whole body (MFBIA-body), Laser Doppler Imaging (LDI) and Digital Colour Photography (DCP).
The neuropathy for diabetics was studied in papers I and II. The first study was performed on diabetics and control subjects of both genders. A separation was seen between males and females and therefore the data had to be divided in order to obtain good models. NIR spectroscopy was shown to be a viable technique for measuring neuropathy once the division according to gender was made. The second study on diabetics, where MFBIA-body was added to the analysis, was performed on males exclusively. Principal component analysis showed that healthy reference subjects tend to separate from diabetics. Also, diabetics with severe neuropathy separate from persons less affected.
The preliminary study presented in paper III was performed on breast cancer patients in order to investigate if NIR, LDI and DCP were able to detect radiotherapy induced erythema. The promising results in the preliminary study motivated a new and larger study. This study, presented in papers IV and V, intended to investigate the measurement techniques further but also to examine the effect that two different skin lotions, Essex and Aloe vera have on the development of erythema. The Wilcoxon signed rank sum test showed that DCP and NIR could detect erythema, which is developed during one week of radiation treatment. LDI was able to detect erythema developed during two weeks of treatment. None of the techniques could detect any differences between the two lotions regarding the development of erythema.
The use of NIR to diagnose cutaneous malignant melanoma is presented as unpublished results in this thesis. This study gave promising but inconclusive results. NIR could be of interest for future development of instrumentation for diagnosis of skin cancer.

Forests have been proposed as a means of reducing atmospheric carbon dioxide levels due to their ability to store carbon as biomass. To quantify the amount of atmospheric carbon sequestered by forests, biomass and density estimates are often needed. This study develops, implements, and tests an individual tree-based algorithm for obtaining forest density and biomass using orthophotographs and small footprint LiDAR imagery. It was designed to work with a range of forests and image types without modification, which is accomplished by using generic properties of trees found in many types of images. Multiple parameters are employed to determine how these generic properties are used. To set these parameters, training data is used in conjunction with an optimization algorithm (a modified Nelder-Mead simplex algorithm or a genetic algorithm). The training data consist of small images in which density and biomass are known. A first test of this technique was performed using 25 circular plots (radius = 15 m) placed in young pine plantations in central Virginia, together with false color othophotograph (spatial resolution = 0.5 m) or small footprint LiDAR (interpolated to 0.5 m) imagery. The highest density prediction accuracies (r2 up to 0.88, RMSE as low as 83 trees / ha) were found for runs where photointerpreted densities were used for training and testing. For tests run using density measurements made on the ground, accuracies were consistency higher for orthophotograph-based results than for LiDAR-based results, and were higher for trees with DBH ≥10cm than for trees with DBH ≥7 cm. Biomass estimates obtained by the algorithm using LiDAR imagery had a lower RMSE (as low as 15.6 t / ha) than most comparable studies. The correlations between the actual and predicted values (r2 up to 0.64) were lower than comparable studies, but were generally highly significant (p ≤ 0.05 or 0.01). In all runs there was no obvious relationship between accuracy and the amount of training data used, but the algorithm was sensitive to which training and testing data were selected. Methods were evaluated for combining predictions made using different parameter sets obtained after training using identical data. It was found that averaging the predictions produced improved results. After training using density estimates from the human photointerpreter, 89% of the trees located by the algorithm corresponded to trees found by the human photointerpreter. A comparison of the two optimization techniques found them to be comparable in speed and effectiveness.Ph. D.

Thesis (MScEng)-- Stellenbosch University, 2013.ENGLISH ABSTRACT: Diabetic- and hypertensive retinopathy are two common causes of blindness that can be prevented by managing the underlying conditions. Patients suffering from these conditions are encouraged to undergo regular examinations to monitor the retina for signs of deterioration. For these routine examinations an ophthalmoscope is used. An ophthalmoscope is a relatively inexpensive device that allows an examiner to directly observe the ocular fundus (the interior back wall of the eye that contains the retina). These devices are analog and do not allow the capture of digital imagery. Fundus cameras, on the other hand, are larger devices that o er high quality digital images. They do, however, come at an increased cost and are not practical for use in the eld. In this thesis the design and implementation of a system that digitises imagery from an ophthalmoscope is discussed. The main focus is the development of software algorithms to increase the quality of the images to yield results of a quality closer to that of a fundus camera. The aim is not to match the capabilities of a fundus camera, but rather to o er a cost-e ective alternative that delivers su cient quality for use in conducting routine monitoring of the aforementioned conditions. For the digitisation the camera of a mobile phone is proposed. The camera is attached to an ophthalmoscope to record a video of an examination. Software algorithms are then developed to parse the video frames and combine those that are of better quality. For the parsing a method of rapidly selecting valid frames based on colour thresholding and spatial ltering techniques are developed. Registration is the process of determining how the selected frames t together. Spatial cross-correlation is used to register the frames. Only translational transformations are assumed between frames and the designed algorithms focuses on estimating this relative translation in a large set of frames. Methods of optimising these operations are also developed. For the combination of the frames, averaging is used to form a composite image. The results obtained are in the form of enhanced grayscale images of the fundus. These images do not match those captured with fundus cameras in terms of quality, but do show a signi cant increase when compared to the individual frames that they consists of. Collectively a set of video frames can cover a larger region of the fundus than what they do individually. By combining these frames an e ective increase in the eld of view is obtained. Due to low light exposure, the individual frames also contain signi cant noise. In the results the noise is reduced through the averaging of several frames that overlap at the same location.
AFRIKAANSE OPSOMMING: Diabetiese- en hipertensiewe retinopatie is twee algemene oorsake van blindheid wat deur middel van die behandeling van die onderliggende oorsake voorkom kan word. Pasiënte met hierdie toestande word aangemoedig om gereeld ondersoeke te ondergaan om die toestand van die retina te monitor. 'n Oftalmoskoop word gebruik vir hierdie roetine ondersoeke. 'n Oftalmoskoop is 'n relatiewe goedkoop, analoë toestel wat 'n praktisyn toelaat om die agterste interne wand van die oog the ondersoek waar die retina geleë is. Fundus kameras, aan die ander kant, is groter toestelle wat digitale beelde van 'n hoë gehalte kan neem. Dit kos egter aansienlik meer en is dus nie geskik vir gebruik in die veld nie. In hierdie tesis word die ontwerp en implementering van 'n stelsel wat beelde digitaliseer vanaf 'n oftalmoskoop ondersoek. Die fokus is op die ontwikkeling van sagteware algoritmes om die gehalte van die beelde te verhoog. Die doel is nie om die vermoëns van 'n fundus kamera te ewenaar nie, maar eerder om 'n koste-e ektiewe alternatief te lewer wat voldoende is vir gebruik in die veld tydens die roetine monitering van die bogenoemde toestande. 'n Selfoonkamera word vir die digitaliserings proses voorgestel. Die kamera word aan 'n oftalmoskoop geheg om 'n video van 'n ondersoek af te neem. Sagteware algoritmes word dan ontwikkel om die videos te ontleed en om videogrepe van goeie kwaliteit te selekteer en te kombineer. Vir die aanvanklike ontleding van die videos word kleurband drempel tegnieke voorgestel. Registrasie is die proses waarin die gekose rame bymekaar gepas word. Direkte kruiskorrelasie tegnieke word gebruik om die videogrepe te registreer. Daar word aanvaar dat die videogrepe slegs translasie tussen hulle het en die voorgestelde registrasie metodes fokus op die beraming van die relatiewe translasie van 'n groot versameling videogrepe. Vir die kombinering van die grepe, word 'n gemiddeld gebruik om 'n saamgestelde beeld te vorm. Die resultate wat verkry word, word in die vorm van verbeterde gryskleur beelde van die fundus ten toon gestel. Hierdie beelde is nie gelykstaande aan die kwaliteit van beelde wat deur 'n fundus kamera geneem is nie. Hulle toon wel 'n beduidende verbetering teenoor individuele videogrepe. Deur dat 'n groot versameling videogrepe wat gesamentlik 'n groter area van die fundus dek gekombineer word, word 'n e ektiewe verhoging van data in die area van die saamgestelde beeld verkry. As gevolg van lae lig blootstelling van die individuele grepe bevat hul beduidende ruis. In die saamgestelde beelde is die ruis aansienlik minder as gevolg van 'n groter hoeveelheid data wat gekombineer is om sodoende die ruis uit te sluit.

L’interprétation du contenu de l’image est un objectif très important dans le traitement de l’image et la vision par ordinateur. Par conséquent, plusieurs chercheurs y sont intéressés. Une image contient des informations multiples qui peuvent être étudiés, telles que la couleur, les formes, les arêtes, les angles, la taille et l’orientation. En outre, les contours contiennent les structures les plus importantes de l’image. Afin d’extraire les caractéristiques du contour d’un objet, nous devons détecter les bords de cet objet. La détection de bords est un point clé dans plusieurs applications, telles que :la restauration, l’amélioration de l’image, la stéganographie, le filigrane, la récupération, la reconnaissance et la compression de l’image, etc. Toutefois, l’évaluation de la performance de la méthode de détection de bords reste un grand défi. Les images numériques sont parfois modifiées par une procédure légale ou illégale afin d’envoyer des données secrètes ou spéciales. Afin d’être moins visibles, la plupart des méthodes stéganographiques modifient les valeurs de pixels dans les bords/textures de parties de l’image. Par conséquent, il est important de détecter la présence de données cachées dans les images numériques. Cette thèse est divisée principalement en deux parties.La première partie discute l’évaluation des méthodes de détection des bords du filtrage, des contours et des angles. En effet, cinq contributions sont présentées dans cette partie : d’abord, nous avons proposé un nouveau plan de surveillance normalisée de mesure de la qualité. En second lieu, nous avons proposé une nouvelle technique pour évaluer les méthodes de détection des bords de filtrage impliquant le score minimal des mesures considérées. En plus, nous avons construit une nouvelle vérité terrain de la carte de bords étiquetée d’une manière semi-automatique pour des images réelles.En troisième lieu, nous avons proposé une nouvelle mesure prenant en compte les distances de faux points positifs pour évaluer un détecteur de bords d’une manière objective. Enfin, nous avons proposé une nouvelle approche de détection de bords qui combine la dérivée directionnelle et l’homogénéité des grains. Notre approche proposée est plus stable et robuste au bruit que dix autres méthodes célèbres de détection. La seconde partie discute la stéganalyse de l’image en couleurs, basée sur l’apprentissage automatique (machine learning). En effet, trois contributions sont présentées dans cette partie : d’abord, nous avons proposé une nouvelle méthode de stéganalyse de l’image en couleurs, basée sur l’extraction de caractéristiques de couleurs à partir de corrélations entre les gradients de canaux rouge, vert et bleu. En fait, ces caractéristiques donnent le cosinus des angles entre les gradients. En second lieu, nous avons proposé une nouvelle méthode de stéganalyse de l’image en couleurs, basée sur des mesures géométriques obtenues par le sinus et le cosinus des angles de gradients entre tous les canaux de couleurs. Enfin, nous avons proposé une nouvelle méthode de stéganalyse de l’image en couleurs, basée sur une banque de filtres gaussiens orientables. Toutes les trois méthodes proposées présentent des résultats intéressants et prometteur en devançant l’état de l’art de la stéganalyse en couleursInterpretation of image contents is very important objective in image processing and computer vision. Wherefore, it has received much attention of researchers. An image contains a lot of information which can be studied such as color, shapes, edges, corners, size, and orientation. Moreover, contours include the most important structures in the image. In order to extract features contour of an object, we must detect the edges of that object. Edge detection results, remains a key point and very important step in wide range of applications such as: image restoration, enhancement, steganography, watermarking, image retrieval, recognition, compression, and etc. An efficient boundary detection method should create a contour image containing edges at their correct locations with a minimum of misclassified pixels. However, the performance evaluationof the edge detection results is still a challenging problem. The digital images are sometimes modify by a legal or illegal data in order to send special or secret data. These changes modify slight coefficient values of the image. In order to be less visible, most of the steganography methods modify the pixel values in the edge/texture image areas. Therefore, it is important to detect the presence of hidden data in digital images. This thesis is divided mainly into two main parts. The first part, deals with filtering edge detection, contours evaluation and corners detection methods. More deeply, there are five contributions are presented in this part: first, proposed a new normalized supervised edge map quality measure. The strategy to normalize the evaluation enables to consider a score close to 0 as a good edge map, whereas a score 1 translates a poor segmentation. Second, proposed a new technique to evaluate filtering edge detection methods involving the minimum score of the considerate measures. Moreover, build a new ground truth edge map labelled in semi-automatic way in real images. Third, proposed a new measure takes into account the distances of false positive points to evaluate an edge detector in an objective way. Finally, proposed a new approach for corner detection based on the combination of directional derivative and homogeneity kernels. The proposed approach remains more stable and robust to noise than ten famous corner detection methods. The second part, deals with color image steganalysis, based on a machine learning classification. More deeply, there are three contributionsare presented in this part: first, proposed a new color image steganalysis method based on extract color features from correlations between the gradients of red, green and blue channels. Since these features give the cosine of angles between gradients. Second, proposed a new color steganalysis method based on geometric measures obtained by the sine and cosine of gradient angles between all the color channels. Finally, proposed a new approach for color image steganalysisbased on steerable Gaussian filters Bank.All the three proposed methods in this part, provide interesting and promising results by outperforming the state-of-art color image steganalysis

Thesis (M. Tech.) - Dept. of Visual Arts and Design, Faculty of Human Sciences - Vaal University of Technology.The digital manipulation of images that are presented as photographs in the media raises issues of interpretation and the possible deception of viewers. The central research question of this study was whether training in the visual arts improves awareness of digital image manipulation of photographs. Secondary aims of the research were to investigate correlations between visual production literacy training and awareness of digital image manipulation of photographs as opposed to general visual literacy training. Secondary aims also include the !investigation of attitudes to the manipulation of photographs in relation to different viewing contexts and various levels of manipulation. The literature review provides background information and theoretical frameworks on the nature of the photographic message and how it is read primarily from a semiotic perspective. A further investigation was done into literature regarding the use of attitudes towards and ethical issues surrounding digital manipulation of photographs. In addition, a review of literature on visual literacy supports the argument that awareness of digital manipulation of photographs should and can be improved. For the empirical component of the study, a total of 145 students at the Vaal University of Technology with low, medium and high visual literacy training participated on a voluntary basis. Both qualitative and quantitative data was gathered through a digitally administered questionnaire on six visual images, each manipulated to a different degree. The results show that production literacy, especially specific training in digital image manipulation software, emerged as the main variable to be significantly (beta coefficient = 0.051; Pearson's r value = 0.436) associated with awareness of manipulation techniques as opposed to general visual literacy (standardised regression coefficieFlt = 0.436; Pearson's r = 0.051 ). Findings regarding attitudes to manipulation and the impact of viewing context show no difference between groups. Emanating from these results possibilities for further research were formulated.

Full textAbstract:
Photo enhancement is an important and practical problem in computer vision. In real-word applications, there are massive needs for photo quality enhancement. Image cropping and image color enhancement are two common operations used to improve the visual quality of photographs. By learning from human examples, we propose automatic photo enhancement method which implements these two fundamental operations.For image cropping, we present an automatic cropping technique that accounts for the two primary considerations of people when they crop: removal of distracting content, and enhancement of overall composition. Our approach utilizes a large training set consisting of photos before and after cropping by expert photographers to learn how to evaluate these two factors in a crop. In contrast to the many methods that exist for general assessment of image quality, ours specifically examines differences between the original and cropped photo in solving for the crop parameters. To this end, several novel image features are proposed to model the changes in image content and composition when a crop is applied. The effectiveness of each feature is empirically analyzed in determining a final feature set for crop computation. Our experiments demonstrate improvements of our method over recent cropping algorithms on a broad range of images.
We also present a machine-learned ranking approach for automatically enhancing the color of a photograph. Unlike previous techniques that train on pairs of images before and after adjustment by a human user, our method takes into account the intermediate steps taken in the enhancement process, which provide detailed information on the person's color preferences. To make use of this data, we formulate the color enhancement task as a learning-to-rank problem in which ordered pairs of images are used for training, and then various color enhancements of a novel input image can be evaluated from their corresponding rank values. From the parallels between the decision tree structures we use for ranking and the decisions made by a human during the editing process, we posit that breaking a full enhancement sequence into individual steps can facilitate training. Our experiments show that this approach compares well to existing methods for automatic color enhancement.

"Image enhancement by super-resolution, focus editing and exposure composition." Thesis, 2010. http://library.cuhk.edu.hk/record=b6075257.
Full textAbstract:
Although significant progress has been made in imaging devices during the past few decades, the photographs acquired by digital cameras are still far from perfection due to the physical limitations of hardware such as aperture, lens and sensor. This fact brings out the demand for study on image enhancement: a computational technique that aims to improve the interpretability or perception of information in photographs for human viewers. The work in this thesis mainly focuses on three tasks in image enhancement.Finally, since the radiance of the real world spans several orders of magnitude and its dynamic range dramatically exceeds the capability of the current digital cameras, there often exist some undesirable over- or under-exposed regions in a photograph. The third part of this thesis aims at producing one great looking well-exposed image that is virtually impossible with a single exposure by compositing a stack of photos at different exposures taken with a conventional camera. Particularly, a simple but effective method is presented to describe how to take advantage of the gradient information to accomplish exposure composition in both static and dynamic scenes. Compared to conventional high dynamic range (HDR) imaging work, the proposed approach is quite appealing in practice since it is computationally efficient and easy to use, and frees users from the tedious radiometric calibration and tone mapping steps.
Firstly, since the camera sensor has limited resolution, the acquired images cannot capture the scene very detailedly. Hence, people often resort to a postprocessing technique called super-resolution (SR) to enhance the resolution of the captured images. In the first part of this thesis, two approaches are presented to address the challenging single image SR problem, which is to recover a high-resolution (HR) image from one low-resolution (LR) input. Specifically, a novel learning-based framework is designed specifically for face image SR task from the perspective of DCT domain. In addition, an efficient two-step scheme is developed to super-resolve generic image by exploiting the salient edges of the input LR image.
Secondly, due to the limitation of lens and aperture, some cameras cannot produce pleasant photographs with desired focus setting. For example, portrait photography that requires shallow depth of field (DOF) is not allowed when using the compact point-and-shoot cameras. In the second part of this thesis, a new and complete postprocessing-based focus editing system that is able to handle the tasks of focus map estimation, image refocusing and defocusing, is developed to overcome the optical limitations and create different kinds of novel photos with desired focus setting from an imperfect photo.
Throughout this work, extensive experiments on various real and synthetic image data are conducted to evaluate the performance of the proposed algorithms.

Full textAbstract:
Apartheid housing policies of the pre-1994 South African government, and the low-cost highdensity housing programmes of the post-1994 government, has given rise to numerous urban environmental problems, some of which could be addressed in a cost-effective and sustainable manner through urban greening, while simultaneously promoting biodiversity. Public participation in the planning of urban greening has been identified as being of vital importance, without which urban greening projects run a high, and expensive, risk of failure. Previous studies indicate that the greening priorities of residents in low-cost high-density housing settlements may differ considerably from those of managers and experts tasked with the protection and extension of the natural environment resource base. A system of participatory decision support is therefore required to reconcile the greening requirements of the community, and the ecological benefits of biodiversity. If language, literacy, map literacy and numeracy difficulties are to be avoided, and a sense of place or belonging is to be invoked, such a participatory decision support system should, ideally, be visually based, and capable of generating realistic eye-level depictions of the urban landscape. New computer-based landscape visualisation applications, which can directly utilise GIS, CAD and DEM data to produce detailed photo-realistic viewsheds, were deemed better suited to the task of visualising urban greening than existing GIS based mapping systems, CAD and traditional landscape visualisation methods. This dissertation examines the process of constructing a 3D computer model of the Mount Royal low-cost high-density housing settlement, situated in the eThekwini Municipality, KwaZulu-Natal, South Africa. Visualisations including terrain, natural features, indigenous vegetation, houses and roads were produced and submitted, with a questionnaire, to experts from different disciplines, Mount Royal residents and neighbors. Results from the expert survey indicate moderate support for visualisation in professional decision-making. However, both experts and residents expressed strong support for the accuracy and credibility ofthe visualisations, as well as for their potential in a participatory decision support system.Thesis (M.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

Digital image editing is rooted in the analog practices of photographic retouching from the late nineteenth century. This study interrogated how novel contributions of new media practice can inform understanding of the relationship between digital and analog media. The study also sought to explore new conceptual avenues in the creation of digital art that incorporates key aspects of both new and traditional media. This study employed a literature review of selected discourses related to new media studies. Specifically, the work of scholars Lev Manovich, Jay David Bolter, Richard Grusin, and Filipe Pais on the interplay between traditional and new media formed the cornerstone of the analysis. These discourses contextualise an analysis of several contemporary case studies of digital artists, with a particular focus on John Craig Freeman and the Oddviz collective. These works were selected for the way in which they destabilise conventional notions of digital photography in new media and the way digital content can be ‘displaced’ into a physical space. From this analysis several concepts arise that serve as distinguishing markers for media displacement. These themes include embodiment, memory, identity formation, autotopography, and intermediality. The dissertation concludes with an overview of my work that incorporates the concepts derived from my analysis of the case studies. It discusses how my exhibition Digital Tourist, a mixed media installation, makes use of photogrammetry and AR to displace the private connections of an individual life into the public space of the gallery.
