Abstract:
Without sunlight, imaging devices typically depend on various artificial light sources. However, scenes captured with the artificial light sources often violate the assumptions employed in color constancy algorithms. These violations of the scenes, such as non-uniformity or multiple light sources, could disturb the computer vision algorithms. In this paper, complex illumination of multiple artificial light sources is decomposed into each illumination by considering the sensor responses and the spectrum of the artificial light sources, and the fundamental color constancy algorithms (e.g., gray-world, gray-edge, etc.) are improved by employing the estimated illumination energy. The proposed method effectively improves the conventional methods, and the results of the proposed algorithms are demonstrated using the images captured under laboratory settings for measuring the accuracy of the color representation.

Abstract:
Abstract The authors discuss the spectral estimation of multiple light sources from image data in a complex illumination environment. An approach is proposed to effectively estimate illuminant spectra and the corresponding light sources based on highlight areas that appear on dielectric object surfaces. First, the authors develop a highlight detection method using two types of convolution filters with Gaussian distributions, center-surround and low-pass filters. This method is available even for white surfaces, and it is independent of object color and of viewing and incidence angles. Second, they present an algorithm for estimating the illuminant spectra from extracted highlight areas. Each specular highlight area has a spectral composition corresponding to only one light source among multiple light sources. The spectral image data are projected onto a two-dimensional subspace, where a linear cluster in pixel distribution is detected for each highlight area. Third, the relative positional relationship between highlight areas among different object surfaces is used to identify the light sources on each surface. The authors develop an algorithm based on probabilistic relaxation labeling. The light source for each highlight and the corresponding spectral-power distribution are determined from the iterative labeling process. Finally, the feasibility of the proposed approach is examined in an experiment using a real complex environment, where dielectric objects are illuminated by multiple light sources of light-emitting diode, fluorescence, and incandescence.

Abstract:
A crescente capacidade do poder computacional e a proliferação de dispositivos ao nosso redor vem permitindo o desenvolvimento de novas e sofisticadas interfaces para interação humano-computador que reagem à presença e ao estado de seus usuários. Como o olhar tem a capacidade de transmitir muitas informações sobre o usuário, rastreadores de olhar, dispositivos que estimam a direção para onde uma pessoa olha, tem papel importante no desenvolvimento de tais interfaces. Entre suas aplicações temos o auxílio a pessoas com dificuldades motoras, que podem utilizar um rastreador de olhar como substituto ao mouse, aplicações de diagnóstico, que estudam evidências do comportamento humano, ou ainda o desenvolvimento de interfaces que utilizem a informação sobre o olhar como um canal a mais de comunicação com o usuário para perceber suas intenções. Muitas técnicas para atingir tal objetivo foram desenvolvidas mas as tradicionais ainda oferecem certas dificuldades de uso para seus usuários como a intolerância a movimentos de cabeça e a necessidade de calibração por sessão de uso. Neste trabalho fizemos um levantamento de uma série de técnicas de rastreamento de olhar, indo das mais tradicionais até algumas mais recentes que visam melhorar a facilidade de uso destes sistemas. Uma das técnicas mais promissoras utiliza múltiplas fontes de luz fixadas nos cantos do monitor do computador. Através da análise da posição dos reflexos gerados por essas fontes de luz sobre a córnea, juntamente com a informação da posição da pupila, presentes em imagens capturadas do olho, é possível estimar o ponto observado no monitor. Devido às suas vantagens ela foi escolhida para estudo mais detalhado e implementação. Extensos testes utilizando simulações foram realizados para avaliar seu desempenho. Foi também desenvolvida uma extensão dessa técnica, utilizando um modelo mais preciso do olho, visando melhorar sua precisão. Ao final apresentamos nossa implementação, baseada nessa extensão da técnica original, que é tolerante a movimentação da face e mostramos os resultados obtidos em testes realizados com um grupo de usuários.<br>Recent advances in computing power and the proliferation of computing devices around us allowed the development of new computer interfaces which can react to the presence and state of its users. Since gaze can transmit a lot of information about the user, gaze trackers, devices that can estimate the direction which a person is looking at, have an important role in the development of such interfaces. Among gaze tracking applications, we have aid for people with limited motor skills, human behavior studies, and the development of interfaces that can take gaze information as an additional communication channel with the user. Lots of techniques have been developed to reach this goal, but they have some problems that make them hard to be widely used. These problems are the need of calibration for each use session and the need to keep the user\'s head still. In this work we studied some of the existing gaze tracking techniques, from the more traditional ones to more recent ones. One of the most interesting techniques makes use of multiple light sources fixed at the monitor\'s corners. By analyzing the positions of corneal reflections and the pupil present in captured images of the eye, it is possible to estimate the gaze point on the monitor screen. Due to its advantages this technique was chosen for a deeper study and implementation. Lots of experiments using simulated data have been carried out to validate the technique. Using a more accurate model of the eye, an extension for this technique was also developed to increase its precision. Finally, we present our implementation, that allows for large head movement, as well as test results obtained from real users.

Abstract:
碩士<br>國立交通大學<br>顯示科技研究所<br>102<br>Nowadays light-emitting diode (LED) is widely used for both indoor and outdoor illumination. Owing to the higher modulation bandwidth than the fluorescent lamp, LED is also promising light source for visible light communication (VLC). For achieving uniform illumination environment, delicate LED setup strategies are typically required for controlling the resulting indoor spatial field distribution. For the VLC application, different LEDs are driven by different data signals; hence each receiver may receive optical signals irradiated from different LEDs, and suffers from serious signal interference. To achieve high data rate VLC, it is crucial to solve the signal interference. Additionally, for indoor VLC application using multiple LEDs, it is possible to identify users’ location. Our researches focus on the applications of indoor VLC using multiple LED light sources. The thesis is mainly divided into three sections. In the first section, a model for our indoor VLC system is built. The interference induced signal performance degradation is analyzed by simulations and experiments. In the second section, multiple input multiple output (MIMO) technology is used in our indoor VLC system in order to increase the transmission capacity. Moreover, we evaluate the channel matrix of MIMO by calculating the condition number (CN), and propose improving the CN of channel matrix by rotating the receiver. Finally, we combine the MIMO system with the position identification scheme to achieve illumination, positioning and communication simultaneously. High positioning accuracy is achieved in experiment.

Abstract:
碩士<br>大葉大學<br>資訊管理學系碩士班<br>95<br>Economy has grown rapidly nowadays; therefore, protection of entrepreneurs and houses has been more and more essential. It makes perfect sense that a smart security monitoring system has become the focus of development and research in the field of information technology during the past few years. At present, most of the monitoring systems are handled by manpower, which is inefficient. It is highly likely that operators overlook some certain thing. As a result, it is highly needed to have an automatic video monitoring system. On the other hand, crime rate is far higher at nighttimes than daytimes. It is certainly a difficult but crucial to monitor at nights. In this study, inexpensive webcams are used as equipment of video capture. Also, they are utilized to detect and track mobile light sources the light source intruders bring in the dark. By doing so, we can estimate the track of the light source holder. In the process of tracking multiple light sources, this research takes many factors into account, including multiple-light interference, effect of reflection of background objects, holders or shades of furniture. However, it mainly focuses on tracking multiple-mobile lights in the dark and on estimation of the track of the holder. By harnessing 3225 images among 30 shots of all kinds of stimulations, we detect the location of light sources (the accurate rate is 94.36%) and judge the type of light source (the accurate rate is 93.39%), the distance and features of the light source the accurate rate 93.62%). The results and analysis of errors prove that methodology in this study works.

Abstract:
碩士<br>逢甲大學<br>通訊工程所<br>100<br>Most color constancy algorithms assume a single light source with uniform illumination across the scene. However, this assumption seldom holds in reality. The purpose of this thesis is to develop a color constancy scheme for multiple light sources. Firstly, the luminance of an input image is adjusted automatically and adaptively to eliminate strong variation of illuminating intensity. Then, a near white-balanced image is obtained by appropriately shifting the levels of red, green, and blue channels of the luminance adjusted image. A pixel-wise illumination chromaticity map is estimated from this near white-balance image. Finally, the illumination color of the multiple light sources is obtained by applying the k-means clustering algorithm to the illumination chromaticity map. A true white-balance could be achieved by considering the influence of each light source on every pixel. In addition, the illumination color estimation method developed by the proposed scheme could be applied to evaluate the white-balance performance of the state-of-the-art color image enhancement methods.

Abstract:
碩士<br>國立中興大學<br>資訊科學與工程學系所<br>101<br>Generally, white balancing algorithm is based on a simplified hypothesis which supposes that the light in a scene comes from one single source and is evenly distributed in space. However, this theory is often against reality because there are different light sources existed in the real world. In this paper, we focus on a practical condition that white balancing for multiple light sources. Firstly, we divide an image into individual patches and assume that the light in each patch comes from one source and is evenly distributed in space. The hypothesis fits the settings of traditional white balancing algorithm for single light source, so it is applicable for each patch to calculate its light source. Secondly, the estimated light source in each patch will be grouped so we can get the major light source and the group average. To define accurately the major light source that affects the image, we combine patches in terms of their similarity to the group average and the estimated light source in each patch. Finally we use the white balancing algorithm for the image with multiple light sources. Both of the artificial and authentic images are used to verify the proposed method. Experimental results show that the effectiveness of the proposed method.

Abstract:
碩士<br>國立中央大學<br>光機電工程研究所<br>98<br>The main objective of this thesis is to discuss the optical system for the interior lighting with different light sources. By using the designed light guide element and other optical elements turn the point light source like LED or the linear light source like CCFL into uniformity surface light source. Also we can adjust the color or the color temperature of the lamp by using the red, green, blue or yellow LEDs. In order to establish the whole system model, we use optical simulation software. The system model includes light guide element, light source and reflector. In order to promote the efficiency of the lamp, we could use the reflection film or the reflection coating to turn the light which leak out from the light guide element back. Light which emitting from the light source transmit in the light guide element by total internal reflection. Until light touch the micro-structure which is created on the top of light guide element, it could change the moving direction and emit from the light guide element. The first step is designing the size and the density of the micro-structure which is created on the light guide element to control the uniformity. We first use the CCFLs to design the whole model, and then add LEDs into the model. Finally the uniformity of the system could reach 85%. And we could adjust the color rendering property of the system by changing the position of LEDs or the different types of LED. After the adjustment, the average color rendering index of the system could reach 93. Adjusting color and color temperature of the whole system by changing the ratio of each light source and the range of color temperature could be adjusted form 6500K to 2700K, and then we could discuss the color uniformity and the color rendering property of the system. Finally, we design a lighting lamp with multiple light sources. We could use single light source as lighting. Also we could use both two light sources to change the color temperature of the lamp or adjust the color rendering property of the lamp. According to using different light sources with different colors or different arrangement of light sources, the color temperature which could be adjusted and the color rendering property would be different.

Abstract:
Multiple light source optical flow is a method to compute a dense, local representation of optical flow. The basic idea is to overcome the aperture problem using multiple images of a moving object acquired simultaneously under different conditions of illumination. Each image provides one linear constraint equation. When the optical flow and the 2D motion field coincide these equations are in the same unknowns. Two equations are enough to calculate both velocity componentss. Three or more images over-determine the system, allowing the calculation of confidence measures and making the computation more robust. This thesis presents a parallel, near-real-time implementation of multiple light source optical flow. Three light sources, one red, one green, and one blue, with negligible overlap in the visible spectrum illuminate the work place from different directions. Three separate black and white images corresponding to the three light sources are acquired simultaneously through a 3 CCD 24 bit RGB camera. The processing is done using a network of six independent processors. The encoded optical flow is displayed on a video monitor. For an image of size 240x240 pixels the processing rate is 4 frames/sec. The range of linear behaviour of the system was studied. A comparison with other methods on a synthetic and a real image sequence is presented.

This thesis improves the illumination and imaging function by allocating multiple light sources in different directions so that the edge features of object in microassembly process can be clearly imaged. In addition, enhance features of the object edges can be obtained by switching of different illumination direction of light source. By utilizing the relationship between the object and its shadow in an image to locate the object position, precise positioning of the object is obtained to achieve automated assembly operation. This research uses software to simulate the CCD images for the changes of scattering light field and evaluate different light source configurations related to the image of assembling peg and hole. In the automation of micropeg and hole assembly test, consecutive assembly of two micro pegs of 80μm diameter with holes of 100μm diameter, with clearance ratio 0.2, are undertaken and analyzed.

Abstract:
Polariton devices offer multiple advantages compared to conventional semiconductor devices. The bosonic nature of exciton polaritons offers opportunity of realisation of polariton lasers: coherent light sources based on bosonic condensates of polaritons. The final state stimulation of any transition feeding a polariton condensate has been used in many proposals such as for terahertz lasers based on polariton lasers. Furthermore, large coherence lengths of exciton-polaritons in microcavities open the way to realisation of polariton transport devices including transistors and logic gates. Being bosonic spin carriers, exciton-polaritons may be used in spintronic devices and polarisation switches. This chapter offers an overview on the existing proposals for polariton devices.

Abstract:
This chapter is concerned with a single consideration: the degree of proportionality between a light signal and its resulting electrical output. This is formally referred to as linearity, which depends on the suitability of the chosen PMT and the mode of operation (pulsed or analogue). Applications fall into two groups: analogue operation (DC) and transient applications. Linearity in a pulsed mode of operation concerns both pulse height (charge) and the rate of events. Generally, in the DC mode, only the mean anode current is relevant. Methods for determining both forms of non-linearity are presented, based on actual measurements. Test methods using multiple light sources, bootstrapping, single step (piggyback), and shot noise are investigated. A method for uncovering non-linearity in high-Z scintillators by using coincident gamma emissions (60Co) is demonstrated. An analytical means for correcting results at the 1 % level is provided.

This chapter provides an account of the spatial perspectival characteristics and the self-presence of remembering from-the-outside. The chapter develops the Constructive Encoding approach, according to which the context of encoding may play a role in the construction of observer perspectives. The Constructive Encoding approach recognizes the multiple and multiperspectival sources of information available during perception, and suggests that observer perspectives may be constructed from non-egocentric information available during perceptual experience. This chapter provides a way of understanding the idea that one need not see oneself from-the-outside in order to have a memory that is recalled from-the-outside. This chapter not only provides a better understanding of observer perspectives but also sheds light on the perspectival mind.

This chapter considers four music critics and three performers—Emile Vuillermoz, Charles Koechlin, Louis Laloy, Léon Vallas, D. E. Inghelbrecht, Marguerite Long, and Alfred Cortot—whose writings in the postwar years helped to combat the negative press that surrounded Debussy after his death. Viewing these personalities through the lens of the “reputational entrepreneur” sheds light not only on what they wrote on behalf of Debussy, but also on how and why they wrote what they did. By drawing on multiple sources, this chapter provides an interpretation of their motivations that makes it possible to read between the lines of the narratives they constructed around the figure of Debussy. Indeed, the manner in which they defended and perpetuated Debussy’s reputation was in large part a result of how they renegotiated their own professional positions in the unsettled musical environment of postwar Paris.

Abstract:
Global supply chains extend throughout the developing world, but we know surprisingly little about company–community interaction. This book engages multiple sources of data to map the evolution and contemporary scope of “stakeholder dialogue” in the business and human rights arena. It draws on the 7,000-company database of the Business and Human Rights Resource Centre, and on original interviews with community members in two factory towns in the Dominican Republic, to illustrate economic rights challenges in light manufacturing communities. Tethered Fates maps trends in stakeholder dialogue by region and industry sector globally. It demonstrates that companies tend to engage stakeholders in sectors where the sunk costs are high (such as the extractive sector) rather than in sectors where the threat of exit looms large (such as light manufacturing). The book then offers a view into local community members’ perceptions of the prospects for dialogue with companies and the challenges of everyday life, through comparative case studies of two textile manufacturing towns in the Dominican Republic. Tethered Fates does more than simply explain why stakeholder dialogue often falls short as a vehicle for safeguarding economic rights and promoting community development; it also offers an assessment of the varieties of emerging policy alternatives for moving beyond the current state of practice.

Abstract:
This book presents the only rounded treatment of a key figure in the intellectual history of France and Europe. Jean Bodin (1529/30–1596), jurist, associate of kings and courtiers, and participant in key political events, was the author of works of lasting interest and enduring significance in the fields of political science, historical writing, witchcraft, and a great deal else besides. Best known for his contribution to formulating the modern doctrine of sovereignty, Bodin has also been credited with developing the quantity theory of money and with advocating religious toleration at a decidedly unpropitious time. Yet, while certain aspects of his thought have long attracted and continue to receive a great deal of lively attention, no attempt has been made until now to approach this challenging thinker on a broad front, to consider all his writings, major and minor, and to examine his ideas contextually and in the round. That is precisely what is offered in this deeply researched and wide-ranging study. Deploying a multilingual array of source materials, it devotes particular attention to Bodin’s own use of sources and modes of discourse in the course of analysing each of his works in turn and in considerable detail. And, beyond Bodin himself and his writings, the book sheds far-reaching light on the intellectual world of the late Renaissance writ large—a dynamic environment shaped through the interaction of multiple traditions of thought.

Full text
Abstract:
This handbook is aimed at helping users of PMTs who are faced with the challenge of designing sensitive light detectors for scientific and industrial purposes. The raison d’être for photomultipliers (PMTs) stems from four intrinsic attributes: large detection area, high, and noiseless gain, and wide bandwidth. Detection involves a conversion process from photons to photoelectrons at the photocathode. Photoelectrons are subsequently collected and increased in number by the action of an incorporated electron multiplier. Photon detection, charge multiplication, and many PMT applications are statistical in nature. For this reason appropriate statistical treatments are provided and derived from first principles. PMTs are characterized by a range of photocathodes offering detection over UV to infra-red wavelengths, the sensitivities of which can be calibrated by National Laboratories. The optical interface between light sources and PMTs, particularly for diffuse or uncollimated light, is sparsely covered in the scientific literature. The theory of light guides, Winston cones, and other light concentrators points to means for optimizing light collection subject to the constraints of Liouville’s theorem (étandue). Certain PMTs can detect single photons but are restricted by the limitations of unwanted background ranging in magnitude from a fraction of a photoelectron equivalent to hundreds of photoelectrons. These sources, together with their correlated nature, are examined in detail. Photomultiplier biasing requires a voltage divider comprising a series of resistors or active components, such as FETs. Correct biasing provides the key to linear operation and so considerable attention is given to the treatment of this topic. Electronic circuits and modules that perform the functions of charge to voltage conversion, pulse shaping, and impedance matching are analysed in detail.

The Spirit of Early Evangelicalism sheds new light on the nature of evangelical religion by locating its rise with reference to those consequential changes in Anglo-American society we now routinely acknowledge with the terms Modernity, the Scientific Revolution, and the Enlightenment. Bringing together a wide range of sources, the book makes meaningful connections between the Protestant evangelical awakening and the history of science, law, art, and literature in the eighteenth century. There was a profound turn toward nature and the authority of natural knowledge in each of these discourses and a more democratic public sphere available for debating contemporary concerns. In this modern context, evangelicals forcefully pressed their agenda for “true religion,” believing it was still possible to experience “the life of God in the soul of man.” The results were dramatic and disruptive. This book provides a fresh perspective, and presents new research, on the religious thought of leading figures such as John Wesley and Charles Wesley, George Whitefield, and Jonathan Edwards, but it also traces the significance of evangelical spirituality for elites and non-elites across multiple genres including not only theology, but also natural and moral philosophy, poetry, painting, literature, and music. Viewing devotion, culture, and ideas together, it is possible to see the advent of evangelicalism as a significant new episode in the history of Christian spirituality.

Abstract:
An exhaustive biography of French neuropsychiatrist Georges Gilles de la Tourette (1857–1904) has never been undertaken. Gilles de la Tourette worked closely with the nineteenth-century founder of neurology in Paris, Jean-Martin Charcot. His name is universally known because of the eponymous, disabling syndrome that affects 0.9% of children/adolescents. Unpublished family archives, as well as Gilles de la Tourette’s correspondence with the Parisian journalist Georges Montorgueil, conserved at the national Archives in Paris, were examined together with press and police archives to portray Georges Gilles de la Tourette’s family and professional life in an original light. These archives have never before been studied or made available to the public. How the eponymous syndrome was isolated, the errors initially made in its description, the hidden role of Jean-Martin Charcot, and the disputes with other authors are covered in detail based on multiple sources, original or already published. An in-depth analysis of the genesis of Gilles de la Tourette’s prolific neurological and psychiatric works within their historical context rounds out this biography. Major figures of neurology of the time are also featured—including Freud, Charcot and his son, Brissaud, and Babiński. Interwoven with Gilles de la Tourette’s life and times are discussions of politics, theater, literature, the 1900 Paris World’s Fair, and numerous letters exchanged with Jules Claretie of the Académie Française to highlight his significant involvement in each of these domains. The book concludes with a complete bibliography of all works written by Gilles de la Tourette, compiled for the first time.

Abstract:
The theme of this special collection of papers, the lived experiences of women who belong to religious minorities, has been a blind spot both in international development policy engagement and in much of the international scholarship on women, security and peace. Women who belong to religious minorities, who are socioeconomically excluded and are vulnerable to multiple sources of gender-based violence in Pakistan seem to have fallen through the cracks of the ‘leave no one behind’ agenda. The aim of this volume is to shed light on the day-to-day experiences of women and their families who belong to the Ahmadiyya, Christian, Hindu and Hazara Shia religious minorities in Pakistan. Each of the papers in this collection exposes the complexity of the intersections of gender, class and religious marginality in shaping the realities for women from these religious minorities.

Abstract:
This report describes the results of technical analysis, field tests, and laboratory tests that were performed for LED highway lighting options by the Energy Efficiency and Reliability Center (EERC) at Purdue University Northwest for the Indiana Department of Transportation (INDOT). This effort was conducted over the past 3 years to evaluate and test the technology and viability of using modern highway lighting technology to enhance energy efficiency, safety, security, and economic development of communities and roadways. During the testing period there was a continuous discussion between INDOT and EERC regarding the laboratory and field testing of INDOT approved luminaires submitted by vendors. There were multiple discussions with INDOT and vendors regarding the individual details and issues for the 29 luminaires that were tested. A comparison study was conducted by EERC of the various alternatives and comparison to currently installed luminaires. Data was collected for field tests of the luminaires by EERC and INDOT personnel for the luminaires. Field data was evaluated and compared to lighting models using vendor supplied ies data files. Multiple presentations were made at 3 separate Purdue Road Schools regarding the results and procedures of the testing program by EERC in conjunction with INDOT. A total of 22 final reports, considered confidential by INDOT, for individual vendor luminaires have been prepared as part of this effort. These reports were submitted sequentially to INDOT as testing was completed during the course of this effort. A total of 29 luminaires were tested. Some luminaire testing was terminated during testing due to design issues or vendor requests. All testing was summarized in the INDOT specification sheet attached to each report. Observations regarding the consistency of the supplied test luminaire with the requirements of Section 7.2 of the INDOT test procedure “Procedure for evaluation and approval list requirements for solid state ballasted luminaires ITM 957-17P” is provided in the Appendix to the report for each luminaire. Details regarding how these tests were performed and the respective associated evaluation of performance and reliability are provided in the report. This effort included: consideration of published and vendor information; appraisal of products consistent with national industry standards; review of physical design, thermal performance; laboratory testing of photopic performance, reliability, life cycle data and characteristics, and power characteristics; technical and probabilistic risk studies; and field testing and analysis of LED light sources including comparison to currently installed conventional light sources. Assistance in preparing INDOT standards for highway lighting was provided on multiple occasions.
