Abstract (sommario):

In this paper different approaches for digital video recording in vehicles are examined, with weight on video quality. Different video compression algorithms were gone through and the conclusion was that inter-frame compression, like MPEG video delivers better video quality than intra-frame algorithms, for example Wavelet. The main drawback is that it is difficult to extract single frames, which leads to difficulties when for example backwards-playability is needed. To demonstrate how digital video recording can be done a demonstrator was built. Therefore, when the decision to use MPEG compression was made, a market research was done and a video grabber expansion card for PCs was bought. The report describes the hardware and software developments that had to be made to run the video recorder.

The result of the thesis was this report and a functioning recorder. The delivered video quality was fair and it was also remote controlled.

International Telemetering Conference Proceedings / October 13-16, 1986 / Riviera Hotel, Las Vegas, Nevada
Standard video cassette recorders (VCR’s) are relatively inexpensive, small, and capable of recording large quantities of data for hours. The problem with using VCR’s to record pulse code modulated (PCM) digital data is that glitches are recorded in the serial data stream coincident with the video sync pulses. This problem can be solved by formating the PCM data stream and synchronizing the video sync pulses to the PCM data.

Abstract (sommario):

With the quick abandonment of VCR technology and the adoption of digital and online replacements, people give up freedom and personal power in the name of perceived convenience. VCRs and VHS tapes served two needs: the need to time-shift programming and the need to archive The internet and DVR technology fulfill the first need, that of time-shifting, but completely ignore the need of people to archive, which is a need many people don't even realize they have until they are no longer able to archive programs in both an audio/visual and physical manner. The disappearance of physical recording also makes it impossible for others to use ones VHS tapes for anthropological investigation. DVR records do not end up in thrift stores, or flea markets, and are not easily bequeathed after a person passes. By investigating one man's VHS collection, encouraging others to use tapes, and using tapes as a raw material with which to create new work, I hope to inspire others to realize what they have lost, or perhaps, given up.

ITC/USA 2009 Conference Proceedings / The Forty-Fifth Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2009 / Riviera Hotel & Convention Center, Las Vegas, Nevada
The F-35 program, known as the Joint Strike Fighter (JSF), is the largest DOD program ever awarded. There are three F-35 variations, each intended to meet the specific needs of the Air Force, Navy, Marine Corps, and Allies. The F-35 Joint Strike Fighter represents the newest advanced military aircraft to make use of Fibre Channel as its primary avionics information transport network. In addition to its use for carrying tactical information systems data, the Fibre Channel network will also transport the real-time digital video used in the cockpit; primarily the pilot's helmet mounted display (HMD) and the high-resolution configurable panoramic cockpit display (PCD). In addition to the fighter's instrumentation configuration for orange wire and avionics data, the aircraft will carry a separate instrumentation package to allow for both the recording and telemetry of either high-resolution Fibre Channel digital video or standard resolution analog video inputs during flight tests. This multiplexer is designed to record cockpit video and audio data, while supporting an option for the test engineer to select up to three out of eight video and audio inputs for real-time telemetry to the ground. This paper describes the architecture of this system, along with the techniques used to reduce the 5 MBps Fibre Channel digital video to a bandwidth acceptable for telemetry.

Abstract (sommario):

This creative project consists of a short fiction film which is finished on DVD and features a full length video commentary. The video commentary is an invention of my own which utilizes an often overlooked element of DVD technology, the multi-angle ability, to effectively merge two of the most popular features of modern motion picture DVD releases: the director's commentary and the production documentary. The disk actually contains two tracks of video, each of identical length. One is the film; the other is a documentary on the making of the film, with certain sections that correspond in real time with events in the film. The user has the ability to switch between tracks at anytime for comparison. This to my knowledge has never been done before, and because of the enormous popularity of the DVD and these features, may find widespread application. This project, while only an exploration of its potential, shows that the idea has feasibility and legitimacy.

Abstract (sommario):

Problems in automated video surveillance analysis caused by illumination changes are explored, and solutions are presented. Controlled experiments are first conducted to measure the responses of color targets to changes in lighting intensity and spectrum. Surfaces of dissimilar color are found to respond significantly differently. Illumination compensation model error is reduced by 70% to 80% by individually optimizing model parameters for each distinct color region, and applying a model tuned for one region to a chromatically different region increases error by a factor of 15. A background model--called BigBackground--is presented to extract large, stable, chromatically self-similar background features by identifying the dominant colors in a scene. The stability and chromatic diversity of these features make them useful reference points for quantifying illumination changes. The model is observed to cover as much as 90% of a scene, and pixels belonging to the model are 20% more stable on average than non-member pixels. Several illumination compensation techniques are developed to exploit BigBackground, and are compared with several compensation techniques from the literature. Techniques are compared in terms of foreground / background classification, and are applied to an object tracking pipeline with kinematic and appearance-based correspondence mechanisms. Compared with other techniques, BigBackground-based techniques improve foreground classification by 25% to 43%, improve tracking accuracy by an average of 20%, and better preserve object appearance for appearance-based trackers. All algorithms are implemented in C or C++ to support the consideration of runtime performance. In terms of execution speed, the BigBackground-based illumination compensation technique is measured to run on par with the simplest compensation technique used for comparison, and consistently achieves twice the frame rate of the two next-fastest techniques.

Abstract (sommario):

Through this research, engineering students and conservation biologists constructed an off-grid video system for observing western burrowing owls in El Paso, Texas. The burrowing owl has a declining population and their range decreasing, driving scientists' interest to see inside the den for observing critical nesting behavior. Texas Parks and Wildlife Department (TPWD) biologists wanted videos from inside the dark, isolated hillside owl burrows. This research yielded a replicable multi-camera prototype, empowering others to explore applications of engineering and wildlife monitoring. The remote station used an off-the-shelf video recording system, solar panels, charge controller, and lead acid batteries. Four local K-12 science educators participated in system testing at Lake Ray Roberts State Park through the Research Experiences for Teachers (RET, NSF #1132585) program, as well as four undergraduate engineering students as senior design research.

Abstract (sommario):

Large classes that allow smaller amounts of instructor-student interaction have become more common in today's colleges. The best way to provide needed opportunities for students to overcome this lack of interaction with instructors remains unidentified. This research evaluated the use of video lecture capture (VLC) as a supplemental method for teacher-student interaction and what, if any, impact it and attendance have on student performance in large lecture courses. This ex post facto study conducted at a Northeastern research university utilized cognitive and andragogical frameworks to examine the relationships between the independent variables frequency of video viewing, quantity of videos viewed, and course attendance, as well as their impact on course performance in a large lecture course (N=329). Data sources included archival data from the learning management system and student survey responses. Analysis included a series of two-way ANOVA tests. The results indicated that the frequency of video viewing was found to have a significant positive effect on course performance (F = 3.018, p = .030). The number of VLC videos not viewed was also found to have a significant negative effect on course performance (F = 1.875, p = 0.016). Other independent variables were not found to have any significant main effect or interaction effect with the dependent variable, course performance. Findings from this research may be used by educators, students, and administrators planning course sizes and availability to better understand the relationship between these variables and how VLC can be used effectively in large lecture classes thus leading to improved efficacy in VLC use.

Abstract (sommario):

Background. Instant replay allows an application to highlight events without exporting a video of the whole session. Hardware-accelerated video encoding allows replay footage to be encoded in real-time with less to no impact on the runtime performance of the actual simulation in the application. Hardware-accelerated video encoding, however, is not supported on all devices such as low-tier mobile devices, nor all platforms like web browsers. When hardware-acceleration is not supported, the replay has to be encoded using a software-implemented encoder instead. Objectives. To evaluate if recording rendering API commands is a suitable replacement of real-time encoding when hardware-accelerated video encoding is not supported. Method. An experimental research method is used to make quantitative measurements of the proposed approach, Reincore, and a real-time encoder. The measured metrics is frame time and memory consumption. The Godot game engine is modified with modules for real-time video encoding (H.264, H.265 and VP9 codecs) and rendering API command recording and replaying. The engine is also used to create test scenes to evaluate if object count, image motion, object loading/unloading, replay video resolution and replay video duration has any impact on the runtime overhead of frame time and memory consumption. Results. The implemented rendering API command replayer, Reincore, appears to have minimal to no impact on the frame time overhead in all scenarios, except for a spike in increased frame time when the replayer initializes synchronization. Reincore show to be overall inferior to real-time video encoding in terms of runtime memory overhead. Conclusions. Overall, real-time encoding using the H.264 or H.265 show a similar result in frame time as recording rendering commands. However, command recording implies a more significant overhead of memory usage than real-time encoding. The frame time of using the VP9 codec for real-time encoding is inferior to recording rendering API commands.
Bakgrund. Återspelning tillåter applikationer att visa upp händelser utan att exportera en video för hela sessionen. Hårdvaruaccelererad videokodning tillåter video av återspelning att kodas i realtid med minimal påverkan på applikationens prestanda för simulering. Hårdvaruaccelererad videokodning stöds dock inte alltid på alla enheter eller plattformar, så som lågt presterande mobila enheter eller webbläsare. När hårdvaruacceleration inte stöds, måste videokodning ske med en mjukvarubaserad implementering istället. Syfte. Att utvärdera om återspelning genom inspelade renderingskommandon som fördröjer arbetet för videokodning är ett lämpligt alternativ till videokodning i realtid, när hårdvaruacceleration inte stöds. Metod. En experimentel forskningsmetod används för att samla kvantitativ mätdata från den föreslagna tillvägagången, Reincore, and en realtidsvidekodare. Mätdatan består av bildtid och minnesanvändning. Genom att modifiera spelmotorn Godot skapas moduler för realtids-videokodning samt inspelning av renderingskommandon. Spelmotorn används också för att skapa testscener för att utvärdera om antal objekt, bildrörelse, skapande av objekt under körning, upplösning eller videolängd har någon inverkan på bildtid eller minnesanvändning. Resultat. Den implementerade renderingskommando-inspelaren, Reincore, visar minimal påverkan på bildtid, med undantag för en temporär ökning när återspelaren initierar synkronisering. Reincore visar sig vara underlägsen till realtids-videokodning när det gäller minnesanvändning. Slutsatser. Realtids-videokodning med H.264 eller H.265 som video-codec visar övergripande bättre resultat för återspelning än renderingskommandoinspelning, när det gäller både bildtid samt minnesanvändning. Bildtiden för VP9 video-codec för realtids-videokodning visar däremot sämre resultat än renderingskommandinspelning.

Abstract (sommario):

This study examines the possibility of creating original video-based content for the video-enabled iPod that was released in October 2005. Current trends show that existing content created for conventional media like television, cinema and computers are simply being ported over to this new medium. However, when this project began, none of the production studios are concentrating on creating content specifically for this medium, which has its own unique properties like portability, screen size and the ability to easily start and pause content as required. The purpose of this project is to prove that such medium-specific content can be created and made financially viable for the creators. Further, this hypothesis is put to the test by presenting it to a group of Ball State University students and their responses are examined in detail.

Abstract (sommario):

This practice-based thesis offers a new approach to editing processes that take place during the recording and subsequent editing of an individual speaking directly to a camera. Rosalind Krauss identified all performance to camera as narcissistic (1976), which includes the subset of artists’ direct address to camera, and since then the area has been widely understood within a psychoanalytical framework. This new approach provides a non-psychoanalytical perspective on direct address to camera, taking into account linguistic self-editing during the generation of speech (Skinner, 1957, p. 370) and technological editing processes once the speech has been recorded. While ‘artists’ film and video is a distinct form of cultural practice with its own autonomy’ in relation to mainstream film (Rees, 1999, p. vii), editing practices within the field of artists’ direct address to camera show no such independence and widely adopt techniques and terminology from the mainstream canon. I consider ways that the language and practice of editing can be expanded beyond the mainstream, and I introduce a transdisciplinary approach to the editing of speech, which is between, across and ‘beyond all disciplines’ (Nicolescu, 2008, p. 2). My practice plays a major role in developing a context for this enquiry. I use the video process, artist’s books, transcription, drawing and text to add to the existing vocabulary of mainstream editing. I create a new technique called blindediting, which involves cutting out video material without looking at it. Finally, I discuss my publication A Relational [Video] Grammar: Extrapolation (2013) which illustrates my transdisciplinary approach and explores the new language that I have developed for editing speech. My research provides a new perspective on the editing of speech in artists’ direct address to camera and suggests that a transdisciplinary understanding of editing practices can shed light on existing works within artists’ film and video.

Abstract (sommario):

Colorectal cancer is the second leading cause of cancer-related deaths behind lung cancer in the United States. Colonoscopy is the preferred screening method for detection of diseases like Colorectal Cancer. In the year 2006, American Society for Gastrointestinal Endoscopy (ASGE) and American College of Gastroenterology (ACG) issued guidelines for quality colonoscopy. The guidelines suggest that on average the withdrawal phase during a screening colonoscopy should last a minimum of 6 minutes. My aim is to classify the colonoscopy video into insertion and withdrawal phase. The problem is that currently existing shot detection techniques cannot be applied because colonoscopy is a single camera shot from start to end. An algorithm to detect phase boundary has already been developed by the MIGLAB team. Existing method has acceptable levels of accuracy but the main issue is dependency on MPEG (Moving Pictures Expert Group) 1/2. I implemented exhaustive search for motion estimation to reduce the execution time and improve the accuracy. I took advantages of the C/C++ programming languages with multithreading which helped us get even better performances in terms of execution time. I propose a method for improving the current method of colonoscopy video analysis and also an extension for the same to make it usable for real time videos. The real time version we implemented is capable of handling streams coming directly from the camera in the form of uncompressed bitmap frames. Existing implementation could not be applied to real time scenario because of its dependency on MPEG 1/2. Future direction of this research includes improved motion search and GPU parallel computing techniques.

Resumo: O objetivo deste trabalho foi comparar o mecanismo de proteção de vias aéreas no processo de deglutição de crianças com paralisia cerebral, considerando dois padrões posturais. Foi realizada avaliação videofluoroscópica da deglutição em 18 crianças de dois a 13 anos, de ambos os sexos, portadoras de paralisia cerebral do tipo tetraparética espástica, atetósica ou mista, que se alimentam, habitualmente, em posição de hiperextensão cervical. Foram oferecidos: 3 e 5ml de alimento opaco nas consistências pastosa fina e líquida, além de deglutição livre em posição sentada a 90º e em hiperextensão cervical. A análise dos eventos de aspiração e penetração foi feita de acordo com uma escala de oito pontos (Penetration-Aspiration Scale), segundo Rosenbek et al. (1996), determinados pela profundidade que o material passa pela via aérea e se o material que entra é ou não expelido. O mecanismo de proteção das vias aéreas no processo de deglutição de crianças com PC foi tão favorável à aspiração traqueal no padrão de hiperextensão cervical, quanto no posicionamento a 90º. Com o posicionamento em hiperextensão cervical, as crianças deglutiram o menor volume, na consistência líquida, com mais segurança para as vias aéreas, quando comparado à deglutição de 5ml e à deglutição livre da mesma consistência e posicionamento. Não houve diferença estatisticamente significante entre as consistências testadas. A idade das crianças não apresentou relação com a proteção das vias aéreas nas diferentes consistências e volumes oferecidos nos dois posicionamentos
Abstract: The objective of this paper is to compare the airway protection mechanism during the swallowing in children with cerebral palsy (CP), in two standard postures. The videofluoroscopy evaluation of swallowing was carried out in 18 children from two to 13 years old, from both genders, carriers of specific cerebral palsy conditions: spastic tetraparetic CP, atetosic CP or mixed who are usually fed in cervical hyperextension position. They were offered 3 and 5ml of two opaque food textures: thin paste food and liquid, and also free swallowing in seated position at 90º and cervical hyperextension. The analyses of aspiration and penetration events were conducted following an 8 level-scale (Penetration-Aspiration Scale), according to Rosenbek et. al. (1996), defined by the deepness that the material reaches across the airway and whether the material that enters is expelled or not. The cervical hyperextension was not an efficient compensation and that the swallowing process in this position was as favorable to the traqueal aspiration, as the swallowing process with positioning at 90º. With positioning in cervical hyperextension the children swallowed the smaller volume (3ml), in the liquid texture, with more safety to the airway, compared to the 5ml swallowing and the free swallowing of the same texture and positioning. There were not statistically significant differences between the children swallowing seated at 90º position and in cervical hyperextension; the same occurred with the tested food textures. Ultimately, could be also observed that the children¿s age did not present correlation with the answers obtained with any of the remained variables

Abstract (sommario):

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2013.
Cataloged from PDF version of thesis.
Includes bibliographical references (page 59).
This thesis describes the design, implementation, and evaluation of EduCase: an inexpensive automated lecture video recording, post-processing, and viewing system. The EduCase recording system consists of three devices, one per lecture hall board. Each recording device records color, depth, skeletal, and audio inputs. The Post-Processor automatically processes the recordings to produce an output file usable by the Viewer, which provides a more dynamic student experience than traditional video playback systems. In particular, it allows students to flip back to view a previous board while the lecture continues to play in the background. It also allows students to toggle the professor's visibility in and out to see the board they might be blocking. The system was successfully evaluated in blackboard-heavy lectures at MIT and Harvard. We hope that EduCase will be the quickest, most inexpensive, and student-friendly lecture capture system, and contribute to our overarching goal of education for all.

Abstract (sommario):

Active safety systems for automobiles in the form of camera systems have evolved rapidly the last ten years, Autoliv Electronics in Linköping develops multiple such systems. In their development process there is a need for a Break out Box (BoB) to record and playback video and CAN data as if the camera system was used in an actual automobile. The aim of this thesis has been to develop a BoB for these camera systems. The work has been divided into three phases; identiﬁcation of requirements, design of the BoB and implementation of a prototype. The project has addressed four known issues with the currently used BoB; bandwidth, modularity, synchronization and usability. The result is a new BoB which is based on an FPGA connecting to a PC over Gigabit Ethernet. The design is an extendible platform for multiple channels of video, CAN data, other serial data and future extensions. A prototype proves the design concept by successfully recording video for the Autoliv NightVision system onto a PC.

Abstract (sommario):

A fotogrametria é um instrumento de avaliação simples, de baixo custo e objetivo que fornece resultados fáceis de interpretar, precisos e reprodutíveis, sendo muito usada atualmente. Apesar disso, a os protocolos de avaliação por fotogrametria não apresentam uma padronização a ser seguida, tornando difícil a obtenção de um padrão de avaliação com relação a alguns aspectos, como por exemplo, a posição dos pés, carecendo também de informações acerca do comportamento das variáveis associadas a esse tipo de avaliação durante um determinado intervalo de tempo. Essa dissertação foi dividida em dois estudos: Estudo 1: realizou-se uma revisão sistemática com o objetivo de investigar os posicionamentos de pés usados para a realização da avaliação postural semi-estática por meio de fotogrametria. Esse estudo trata-se de uma revisão sistemática de estudos observacionais e ensaios clínicos randomizados e seguiu as recomendações da Colaboração Cochrane. Com as palavras chave “photogrammetry” e “spinal postural evaluation”, realizou-se uma pesquisa nas seguintes bases de dados: PubMed, Science, Scopus, Embase e Bireme. Foram incluídos 40 estudos após crivo dos critérios de elegibilidade, sendo os principais posicionamentos de pés encontrados: autorreferido, paralelos separados, paralelos unidos e posicionamento autorreferido padronizado. Apenas três estudos foram avaliados de baixa qualidade metodológica. Como em nenhum dos estudos incluídos houve comparação de resultados de avaliações realizadas em diferentes posicionamentos de pés, faz-se necessário que estudos que abarquem esse tipo de análise sejam desenvolvidos, também se julgando importante que sejam respeitadas as determinações específicas de cada protocolo de análise. Estudo 2: esse estudo objetivou determinar (1) a reprodutibilidade intra-avaliador das diferentes posições de pés, (2) a classificação das variáveis posturais em estacionária/não estacionária e ergódica/não ergódica, (3) se existe uma posição dos pés com menor variabilidade postural, e (4) se existe uma posição de pés mais confortável para a realização da avaliação postural semi-estática utilizando a fotogrametria. A amostra foi composta por 24 indivíduos adultos de ambos os sexos, sendo eles submetidos à avaliação postural em dois momentos por meio de fotogrametria aonde foram filmados durante 35 segundos em quatro posições de pés: autorreferido (AR), paralelos separados (PS), paralelos unidos (PU) e autorreferido padronizado (ARP). Ao final de cada avaliação o indivíduo apontou em uma escala analógica a sensação subjetiva de desconforto. Após as avaliações, cada filmagem foi dividida em sete fotografias, sendo elas digitalizadas no software Digital Imagem-based Postural Assessment (DIPA). Na análise estatística foram utilizados os seguintes testes: Coeficiente de Correlação Intraclasse (ICC), erro padrão da medida (SEM), mínimo erro detectável (MDC) e média absoluta das diferenças (MAD) para a reprodutibilidade intra-avaliador; ANOVA de medidas repetidas para testar a estacionariedade e ANOVA one-way para testar a ergodicidade das variáveis posturais; Coeficiente de Variação (CV) e ANOVA one-way para análise da variabilidade postural em diferentes posições de pés; e ANOVA oneway para verificar as diferenças entre a sensação subjetiva de desconforto nas posições de pés. A reprodutibilidade das variáveis independeu da posição de pés, sendo todas elas classificadas como excelente. Das doze variáveis analisadas, cinco foram classificadas como estacionárias e ergódicas em todas posições de pés, quatro tiveram classificações dependentes das posições de pés e três foram classificadas como não estacionárias. Quanto à variabilidade postural, os resultados apontam que foram pequenas e semelhantes em todas as posições de pés, não sendo possível apontar uma única posição que apresentasse a menor variabilidade. A posição AR foi a que teve menor sensação subjetiva de desconforto. Concluiu-se que a maioria das variáveis posturais apresentam características estacionárias, que as posições de pés não interferem nos resultados.
Photogrammetry is a low cost and simple objective instrument of evaluation, that provides accurate and reproducible results of easy understanding, being very used nowadays. Nevertheless, the protocols of photogrammetry evaluation do not have a standard to be followed, making it difficult to obtain a standard of evaluation regarding some aspects, for example, the feet positioning, that also lack information about the behavior of variables associated with this type of evaluation for a certain period of time. This dissertation was divided in two studies: Study 1: executed a systematic review with the objective of investigate the feet positioning used to hold the semi-static postural assessment through photogrammetry. This study is a systematic review of observational studies and randomized clinical trials that followed recommendations of the Cochrane Collaboration. With the keywords "photogrammetry" and "spinal postural evaluation", a survey was conducted in the following databases: PubMed, Science, Scopus, Embase and Bireme. 40 studies were included after a scrutiny of eligibility criteria, the main feet positioning found were: self-referred, separated in parallel, united in parallel and standardized self-referred position. Only three studies were graded as low methodological quality. As there was no comparison of results of the included studies in different feet positioning, it is necessary that studies that utilize this type of analysis are developed and it is also deemed important that the specific determinations of each analysis protocol are respected. Study 2: The purpose of this study was to determine (1) the intra-rater reproducibility of different feet positioning, (2) the classification of postural variables in stationary / non-stationary and ergodic / nonergodic, (3) if there is a feet positioning with less postural variability, and (4) whether there is a more comfortable feet positioning for the semi-static posture evaluation using photogrammetry. The sample consisted of 24 adults of both genresas they were submitted totwo stages of postural assessment through photogrammetry, where they were filmed for 35 seconds on four feet positions: self-referred (AR), separated in parallel (PS), parallel and united (PU) and standardized self-referred (ARP). At the end of each assessment, the individual pointed the subjective feeling of discomfort in na analogical scale. After the evaluation, each film was divided into seven photographs, which were scanned in the software Digital Image-based Postural Assessment (DIPA). In the statistical analysis, the following tests were used: intra class correlation coefficient (ICC), standard error of measurement (SEM), minimum detectable error (MDC) and mean absolute differences (MAD) to the intra-rater reproducibility; Repeated measures ANOVA to test the stationarity and one-way ANOVA to test the ergodicity of postural variables; Coefficient of Variation (CV) and one-way ANOVA for analysis of postural variability in different feet positioning; and one-way ANOVA to determine differences between the subjective sensation of discomfort in the feet positioning. Irrespective of feet positioning, the reproducibility of variables it was classified as excellent. Of twelve variables, five were classified as stationary and ergodic in all feet positioning, four had dependent classifications of foot positioning and three were classified as non-stationary. The postural variability, the results were similar in all feet position, it is not possible to identify the position that has the lowest variability. The AR position was the one that had less subjective feeling of discomfort. It was concluded that most variables have stationary characteristics, that feet position does not interfere with results.

Abstract (sommario):

Dieser Artikel stellt einerseits eine Seminarmethodik zum Einsatz des Analytical Short Films (ASF) in der Lehrerbildung und andererseits Ergebnisse einer wissenschaftlichen Begleitforschung zu zwei an der Hochschule für Musik und Theater Leipzig (HMT) durchgeführten Seminaren vor. Dabei wurde die wissenschaftliche Begleitforschung im Rahmen des Verbundprojektes zum Videocampus Sachsen (VCS) gefördert. Unter einem Analytical Short Film wird hierbei ein Kurzfilm von drei bis vier Minuten Dauer verstanden, welcher, ergänzt um eine tabellarische Erläuterung, der sogenannten Complementary Information (CI), eine spezifische Perspektive auf eine gefilmt vorliegende Unterrichtsstunde darstellt. In den Seminaren hatten die Studierenden die Aufgabe, ASFs sowohl aus einer subjektiven Perspektive zur Thematik guter Musikunterricht als auch aus einer theoriegeleiteten Sichtweise zu erstellen und zu diskutieren. Zentrale Ergebnisse der wissenschaftlichen Begleitforschung deuten an, dass die Studierenden durch den Einsatz der Methode vermehrt auf wissenschaftlicher Ebene argumentieren und dass deren Reflexionsstil in Orientierung an verbessert wird.

Abstract (sommario):

This study was deliberately focussed upon the careful examination of a model of professional learning for Middle School teachers, which has at its core, a Teaching and Learning Framework depicting essential elements of effective teaching practice. Set within the context of Middle School classrooms in a Regional Independent school, the intent was to research the impact of the framework on the professional learning of a group of teachers. Research was also undertaken to investigate the effectiveness of feedback and analysis structured around the framework, using video recordings taken from classroom observations. A group of eight Middle School teachers participated actively in the study to determine how the use of video-stimulated reflective processes might affect improvements in their practice and professional learning. Professional learning opportunities were examined and explored in termsof the impact of the observation and feedback cycle on individual teacher’s progress and against rubric levels within the framework. At a time when the issue of the tenuous links between professional learning and school improvement is at the forefront of the educational agenda in schools and school systems, it is of significant importance to be able to reflect on a range of models designed to improve teaching, and in turn student learning outcomes in schools. The Teaching and Learning Framework including its subsequent feedback and professional learning processes investigated within this study served to add valuable perspectives to these links.

Abstract (sommario):

This Critical Review discusses the significance of the author’s published works and their impact on the history of the emergence of British television between 1926 and 1936. Although events in television within this period have since been well-documented, the related debates have tended to be specialist in scope and restricted to technology-centric or institution-centric viewpoints. Within this period of complex, rapid technological change, the author’s published works introduce the principle of embracing multiple disciplines for comparative analysis. The author’s application of that principle opens up long-established views for further debate and provides a re-assessment of early British television within a broader context. The rewards of this approach are a view of events that not only avoids nationalistic bias and restrictions of a single institutional viewpoint, but also tackles the complex inter-dependencies of technology, of service provision and of content creation. These published works draw attention to the revolutionary improvements that enabled the BBC’s 1936 service and the re-definition of television, yet also emphasise the significance of the previous television broadcast services. The most important innovation within these works has been the author’s discovery and in-depth study of artefacts from that earlier period. His recovery, analysis and presentation of video recordings of historic early television from 1927-1935 is original and remains unique. It has had a significant impact on the field of Media Archaeology, where Ernst considers the book Restoring Baird’s Image as a ‘seminal’ work and the overall restoration project ‘a brilliant case of “Digital Humanities” research’ (Appendix 2). The author’s curation of content from the period 1927-1935 enhances our understanding of a time where previously no direct television footage was thought to exist. The author extends his forensic-level investigative ‘hands-on’ techniques from this recovery to the analysis of the surviving artefacts from the time of John Logie Baird’s claimed first demonstration of television in 1926. The results clarify not only the functions of the equipment but also the circumstances and validity of the event, and hence its true place in the history of television.

Abstract (sommario):

Colonoscopy is an endoscopic technique that allows a physician to inspect the mucosa of the human colon. Previous methods and software solutions to detect informative frames in a colonoscopy video (a process called informative frame filtering or IFF) have been hugely ineffective in (1) covering the proper definition of an informative frame in the broadest sense and (2) striking an optimal balance between accuracy and speed of classification in both real-time and non real-time medical procedures. In my thesis, I propose a more effective method and faster software solutions for IFF which is more effective due to the introduction of a heuristic algorithm (derived from experimental analysis of typical colon features) for classification. It contributed to a 5-10% boost in various performance metrics for IFF. The software modules are faster due to the incorporation of sophisticated parallel-processing oriented coding techniques on modern microprocessors. Two IFF modules were created, one for post-procedure and the other for real-time. Code optimizations through NVIDIA CUDA for GPU processing and/or CPU multi-threading concepts embedded in two significant microprocessor design philosophies (multi-core design and many-core design) resulted a 5-fold acceleration for the post-procedure module and a 40-fold acceleration for the real-time module. Some innovative software modules, which are still in testing phase, have been recently created to exploit the power of multiple GPUs together.
