Abstract:
Digital cameras have been widely used in the areas of road transportation, railway transportation as well as security system. To address the position of digital camera in these fields this paper proposed a geometry calibration method based on feature point extraction of arbitrary target. Under the meaning of the questions, this paper first defines four kinds of coordinate system, that is the world coordinate system. The camera's optical center of the coordinate system is the camera coordinate system, using the same point in different coordinate system of the coordinate transformation to determine the relationship between world coordinate system and camera coordinate. And thus determine the camera's internal parameters and external parameters, available transformation matrix and translation vector indicated by the camera's internal parameters of the external parameters and the establishment of a single camera location model. According to the model, using the camera's external parameters to be on the target circle center point in the image plane coordinates.

Abstract:
This paper presents a distributed machine vision inspection system, which has a large field of view (FOV) and can perform high precision, high speed real-time inspection for wide paper sheet detection. The system consists of multiple GigE Vision linescan cameras which connected though Gigabit Ethernet. The cameras are arranged into a linear array so that every camera’s FOV is merged into one large FOV in the meantime the resolution keeps unchanged. In order to acquire high processing speed, the captured images from each camera are sent into one dedicate computer for distributed and parallel image processing. Experimental results show that the system with fine detection capability can satisfy the requirements of real time detection and find out the defects on the production line effectively.

Abstract:
Remote cameras are an increasingly important tool in field-based biological research. Terrestrial researchers can purchase inexpensive off-the-shelf cameras, but aquatic researchers face challenges in adopting similar systems for underwater science. Although technology allows researchers to deploy cameras in any aquatic environment, high procurement costs are often a barrier, particularly for studies that require the collection of lengthy videos. In this note, we provide a detailed guide explaining how to assemble an underwater camera system for less than $425 USD. We focus especially on the construction of the underwater housing, which is typically the most expensive component of an underwater camera system. As described, this system can record 13 h full high-definition videos in depths up to 100 m. It can be constructed and assembled with limited technical background using tools available in most workshops. The guide includes a general overview of the system, a full list of components, detailed instructions on constructing the camera housing, and suggestions on how to mount and use the camera in fieldwork. Our goal for this note is to promote the wider use of remote underwater cameras in aquatic research by making them accessible to those with limited financial means.

Abstract:
Purpose The purpose of this paper is to explore the practical use of video cameras during a study with young children. Design/methodology/approach This paper investigates the use of video cameras in a research study of young children’s utilisation of semiotic tools to communicate during play interactions in a Francophone preschool classroom in British Columbia. It examines the practical in-the-moment decision making of the researcher to support children’s accommodation of the video camera in their play space and ensure rich data were recorded. Findings Children accommodated the video cameras in four distinct ways. These included: curiosity and investigation of the video cameras; engagement in the video recording process with the researcher; incorporation of the video cameras into their play; and disregard of it. Practical implications The findings suggest that video recordings can be an effective method of data collection with young children and provide rich sources of data of the children and their learning through play when the researcher is flexible and responsive and supports children’s accommodation of it. Originality/value Recent advances in recording technology have resulted in the increased use of video recordings as a resource for gathering empirical data in qualitative research. Whilst the ethical considerations related to the use of video recordings as data for analysis in research with young children have been the subject of some discussion (Flewitt, 2005), the practical experience of using video cameras has received less attention.

Abstract:
How do police respond to the presence of cameras and photographers? Many speculative theories have been proposed offering mixed and sometimes contradictory answers to this question. Some theories propose that cameras will deter police misconduct, others suggest that cameras might improve police accountability, others suggest that police might respond to cameras by engaging in a risk-averse style of policing. Unfortunately, little empirical data is available to assess these theories. Drawing on data from a participant-observation research study conducted in Edmonton, Alberta, Canada, this paper helps fill this gap in research and argues that police might be learning to adapt to cameras by engaging in what I call camera-friendly policing. This style of policing involves efforts to control how the police are perceived by photographers, and how they will be perceived by viewers of any recorded footage. In this paper, I outline the basic elements of the police’s camera-friendly tactics, and discuss the implications of these tactics for contemporary understandings of police visibility.

Abstract:
Cameras are ubiquitous and increasingly mobile. While CCTV has captured considerable attention by surveillance researchers, the new visibility of police activities is increasingly produced by incidental sousveillance and wearable on-officer camera systems. This article considers advocacy for policing’s new visibility, contrasting that of police accountability activists who film police with designers and early adopters of on-officer cameras. In both accounts, these devices promise accountability by virtue of their mechanical objectivity. However, to each party, accountability functions rather differently. By attending to the social and legal privileging of police officers’ perspectives, the article provides an explanation for design decisions that produced Taser’s AXON Flex on-officer cameras and for why police are embracing these new technologies. Critics of these cameras cite privacy concerns, officer discretion in operating cameras, and department disclosure of footage. Nonetheless, advocates of police accountability often presume more video documenting police use of force is always helpful. However, the utility of surveillance video is conditioned by point of view. Police agencies in the U.S. are rapidly adopting on-officer camera systems, because they acknowledge ubiquitous surveillance and that these devices aid in nullifying third-party documentation in favor of a perspective that favors officers. As such, these cameras are counter-sousveillance technologies.

Full text
Abstract:
This paper proposes a calibration technique of a stereo gamma detection camera. Calibration of the internal and external parameters of a stereo vision camera is a well-known research problem in the computer vision society. However, few or no stereo calibration has been investigated in the radiation measurement research. Since no visual information can be obtained from a stereo radiation camera, it is impossible to use a general stereo calibration algorithm directly. In this paper, we develop a hybrid-type stereo system which is equipped with both radiation and vision cameras. To calibrate the stereo radiation cameras, stereo images of a calibration pattern captured from the vision cameras are transformed in the view of the radiation cameras. The homography transformation is calibrated based on the geometric relationship between visual and radiation camera coordinates. The accuracy of the stereo parameters of the radiation camera is analyzed by distance measurements to both visual light and gamma sources. The experimental results show that the measurement error is about 3%.

My participatory photography and video project with a First Nations teen drop in center in Northern British Columbia has revealed the benefits of viewing cameras as toys through which community-based research projects can actively engage the world rather than as tools for authoritative observers. The interactive play between the instant feed back of digital cameras placed in youths’ hands creates relationships that allow for the exploration of delicate subjects and intimate moments captured on video. The display of meanings constructed through visual images reveal powerful possibilities for visual research methodologies used in collaborative research.

Abstract:
The primary purpose of this investigation was to determine how magnification and perspective alter a person's judgements of pleasantness for images recorded in photographic prints. The magnification and perspective of four scenes were varied by recording each scene with each of six camera-lens focal lengths (28 mm, 35 mm, 50 mm, 70 mm, 85 mm, and 105 mm) from each of six distances. The distances revolved around a reference distance depending on scene content. The scenes were selected to be typical of the types of one person or multi-person scenes recorded most often by consumers of non-single-lens-reflex (non-SLR) 35 mm camera systems. The psychophysical scaling technique of magnitude estimation was used to assess each subjects' degree of pleasantness for each print in a single stimulus presentation format. The subjects were actual consumers of non-SLR camera systems. The results indicate that a wide variety of lens/distance combinations was found to produce pleasing images for each scene. Specifically, the combination of lens/distance which was representative of currently available non-SLR camera systems was almost always among the highest rated images for each scene. This result indicates that these consumers are quite pleased with the images they currently receive. These results are most easily explained using the theory of a compensation mechanism of picture perception. Suggestions for future research include the study of range effects, different methods of assessment, and attempts at understanding the emotional impact of photographs and how it relates to judgements of pleasantness.<br>Ph.

Abstract:
Widely applicable, quantitative field methods are needed to gather wildlife data for conservation and management initiatives in Turkey. In order to evaluate the use of camera traps in forest habitats of Turkey, we conducted a 5 phase camera trap survey by using 16 passive infrared-triggered cameras with a total sampling effort of 1200 camera trap days in Yaylacik Research Forest, a 50 km2 forest patch of Yenice Forest in Karab&uuml<br>k during January-May 2006. The camera trap survey confirmed the presence of grey wolf (Canis lupus), brown bear (Ursus arctos), wildcat (Felis silvestris), red fox (Vulpes vulpes), badger (Meles meles), pine marten (Martes martes), roe deer (Capreolus capreolus) and wild boar (Sus scrofa) in the study area. The camera trap survey also revealed the presence of jackal (Canis aureus) and brown hare (Lepus europaeus), whose presence were not known by people living and working in the area. Contrary to the local belief, neither camera trapping survey nor ground survey confirmed the presence of lynx (Lynx lynx) in Yaylacik Research Forest. The wolf was observed to be crepuscular and the wildcat showed a diurnal activity pattern. Wildcat seemed to avoid other carnivores spatially and temporally. Simulation studies suggested that camera trap surveys should last 14 days for wolf, 13 days for wildcat, 10 days for pine marten, and 11 days for roe deer, while it is advisable to conduct longer surveys, probably 15-20 days, for wild boar, red fox and brown bears. The estimated population size for wildcat was 9 (SE=2.28227) with 95% confidence interval of 9 to 25 in the study area. A minimum of 6 brown bears were present in the study area. Our study indicated that the local knowledge about the presence of wildlife should be considered by researchers, but it cannot replace scientific surveys conducted by field biologists. This study was the first attempt to assess the presence, relative abundance, activity patterns and diversity of multiple mammal species by the use of camera trapping methodology in Turkey. The results suggest that camera trap surveys have the potential for gathering wildlife data at larger scales in Turkey, where information gap on large mammals is an obstacle for effective management and conservation of mammals.

Abstract:
This thesis describes the theoretical, experimental, and practical aspects of a noise-limited method for scene-change detection in images. The research is divided into three sections: noise analysis and modelling, dual illumination scene-change modelling, and integration of noise into the scene-change model. The sources of noise within commercially available digital cameras are described, with a new model for image noise derived for charge-coupled device (CCD) cameras. The model is validated experimentally through the development of techniques that allow the individual noise components to be measured from the analysis of output images alone. A generic model for complementary metal-oxide-semiconductor (CMOS) cameras is also derived. Methods for the analysis of spatial (inter-pixel) and temporal (intra-pixel) noise are developed. These are used subsequently to investigate the effects of environmental temperature on camera noise. Based on the cameras tested, the results show that the CCD camera noise response to variation in environmental temperature is complex whereas the CMOS camera response simply increases monotonically. A new concept for scene-change detection is proposed based upon a dual illumination concept where both direct and ambient illumination sources are present in an environment, such as that which occurs in natural outdoor scenes with direct sunlight and ambient skylight. The transition of pixel colour from the combined direct and ambient illuminants to the ambient illuminant only is modelled. A method for shadow-free scene-change is then developed that predicts a pixel's colour when the area in the scene is subjected to ambient illumination only, allowing pixel change to be distinguished as either being due to a cast shadow or due to a genuine change in the scene. Experiments on images captured in controlled lighting demonstrate 91% of scene-change and 83% of cast shadows are correctly determined from analysis of pixel colour change alone. A statistical method for detecting shadow-free scene-change is developed. This is achieved by bounding the dual illumination model by the confidence interval associated with the pixel's noise. Three benefits arise from the integration of noise into the scene-change detection method: - The necessity for pre-filtering images for noise is removed; - All empirical thresholds are removed; and - Performance is improved. The noise-limited scene-change detection algorithm correctly classifies 93% of scene-change and 87% of cast shadows from pixel colour change alone. When simple post-analysis size-filtering is applied both these figures increase to 95%.

Por otro lado, se presentan otras prácticas y modalidades de investigación con cámara fotográfica y de vídeo que cuestionan el enfoque representativo y documentalista en el campo de lo audiovisual, más cercanas a perspectivas reflexivas, participativas y deconstructivas en la investigación social. El trabajo se hizo a base de la revisión y análisis de literatura en el campo de la investigación audiovisual etnográfica, así como la documentación fílmica de una movilización comunitaria, La Fiesta del Límber, en el contexto de rescate de terrenos, en Ceiba y Naguabo, Puerto Rico, y que se puede acceder a través de la página http://youtu.be/Vgy2SAb1UIY. Desde estas dos instancias, se reflexiona sobre la autoría textual, la representación de los sujetos, la colaboración investigativa, así como lo que implica desplazarse, investigar e intervenir con cámara en proyectos psicosociales. Finalmente, se presentan las aportaciones de la investigación con cámaras para la práctica psicosocial.<br>This thesis aims to present the possibilities and limits on the use of the camera and the images in research and social intervention, both as a research tool and a format to communicate the research experience with others. It focuses on the emergence of camera and photographic image and its implications in the context of positivist science, as an ally to the interests of the apprehension of reality and an instrument connected to the aims of objectivity and neutrality in social research. Subsequently, we explore other research practices and modalities with video camera that question the representative and documentary approach in the field of audiovisual, closer to reflective, participatory and deconstructive perspectives in social research. The study was based on revision and analysis of literature in the field of audiovisual ethnographic research and a filmic documentation, La Fiesta del Límber, about community mobilization in the context of land rescues in Ceiba and Naguabo, Puerto Rico, which can be accessed at http://youtu.be/Vgy2SAb1UIY. From these two instances, we reflect on the textual authorship, representations we make in our texts, research collaboration, as well as what it implies to move, investigate and intervene with camera in psychosocial projects. Finally, we present the contributions of camera research for psychosocial practices.

Abstract:
Knowledge of the richness of species that inhabit a particular area is an essential metric for both conservationists and practitioners. Relatively cost-efficient and easily standardized solution has occurred in last the decades with the massive digitalization of photography, the camera trap. Such an independent detector is bias-free in the probability of recording objects passing by and in most cases does not disturb animals. Recent discoveries of new mammal species are proof of this. Moreover, camera traps allow for insight into the otherwise hidden behaviour of even the most timid animals. My interest in photography, endangered animal species and nature conservation has led me to the decision to apply a novel method in practice. Me and my team have focused on three different use-confirmation of the accuracy of capture-recapture population estimates, temporal overlaps of invasive species with its prey and competitors, and first ever camera-trapping species inventory in the Niokolo-Koba National Park. Thanks to personal experiences and contacts from World biodiversity hotspots I was able to successfully employ an approach and carry out field studies. I hope that our results will contribute to the development of effective conservation strategies and the methodology itself.

Abstract:
A major disadvantage of shooting on green screen with CGI is that the director cannot see or interact with the virtual elements in the scene and thus get a realistic view of how the end result will look like, and also not being able to make changes as necessary by moving objects and actors around during the shooting session. This disadvantage can be mitigated by the use of previsualization where the director is given a rough take of what the final cut will look like by combining the filmed material with the virtual environment in real-time. This master’s thesis work aims to come up with solutions for improving the film studio Stiller Studios’s previsualization system. This involves a review and integration of game engines for previsualization in a motion control green screen studio, a camera calibration process with blur detection and automatic selection of images as well as research into camera tracking and depth compositing.

<p>The purpose with this essay is to examine how arts and politics integrate to raise urgent messages and call upon social changes. Performance art as an artistic manifestation against the surveillance society has been studied to clarify this integration and through an empirical examination of the anarchistic performance group <i>The Surveillance Camera Players</i>. This group formed in New York City 1996 as a manifestation against the increased use of surveillance cameras in public places in Manhattan. Through performance in front of these cameras, The Surveillance Camera Players are able to express their protest against the surveillance society which, occurring to them, violates citizens constitutionally right to privacy. The development and signification of the surveillance society are examined through theoretical perspective by foremost Michel Foucault, but also by contemporary scientist in that field. Theories about political art have been studied for the understanding of the work of <i>The Surveillance Camera Players</i>.</p><br><p>Uppsatsens syfte är att undersöka hur konst och politik integreras i syfte att föra fram ett budskap och på så sätt försöka påverka till samhällsförändringar. För att tydliggöra detta studeras performancekonst som ett konstnärligt motstånd mot övervakningssamhället och detta exemplifieras genom en empirisk undersökning av den anarkistiska teatergruppen <i>The Surveillance Camera Players, SCP</i>. Denna grupp bildades i New York City 1996, som en manifestation mot det ökande användandet av övervakningskameror på offentliga platser på Manhattan. Genom performance, framför dessa kameror, ger SCP uttryck för sitt motstånd mot övervakningssamhället, som enligt dem, kränker medborgarnas konstitutionella rätt till privatliv. I uppsatsen studeras övervakningssamhällets utveckling och betydelse genom ett teoretiskt perspektiv av framförallt Michel Foucault och även samtida forskare inom området. För förståelsen av <i>The Surveillance Camera Players</i> verksamhet studeras teorier kring politiskt medveten konst. </p>

Abstract:
This book serves as the go-to resource for those who are interested in police body-worn cameras. The first part of the book (chapters 2 and 3) delves deeply into the claims made about BWCs by both advocates and critics, coupled with an exhaustive examination of the research base on each of those claims. Moreover, throughout the book, there are quotes and vignettes from experts in the field who have hands-on experience with police BWCs to illustrate important points. The authors also offer insights on the potential reasons for variation in research findings. In chapter 4, they examine the past, present, and future of police BWCs through two different, complementary lenses. The first is the diffusion of innovations framework. The second lens is the evidence-based policing framework. Both the diffusion of innovation and evidence-based policing frameworks provide insights on the “how and why” questions regarding current rates of BWC adoption, and just as important, they provide an informed position to consider the prospects for BWCs in the future. There are two objectives in chapter 5. The first is a forward-looking review of the next set of challenges for BWC adopters. These challenge center on both human and technological elements of a BWC program. The second objective centers on the importance of planning and implementation. The book ends with a few important takeaway messages on the role of BWCs in policing and how the technology can help police to achieve their core mission.

Abstract:
Studies have indicated that emotions can significantly be influenced by environmental factors; these factors can also significantly influence drivers’ emotional state and, accordingly, their driving behavior. Furthermore, as the demand for autonomous vehicles is expected to significantly increase within the next decade, a proper understanding of drivers’/passengers’ emotions, behavior, and preferences will be needed in order to create an acceptable level of trust with humans. This paper proposes a novel semi-automated approach for understanding the effect of environmental factors on drivers’ emotions and behavioral changes through a naturalistic driving study. This setup includes a frontal road and facial camera, a smart watch for tracking physiological measurements, and a Controller Area Network (CAN) serial data logger. The results suggest that the driver’s affect is highly influenced by the type of road and the weather conditions, which have the potential to change driving behaviors. For instance, when the research defines emotional metrics as valence and engagement, results reveal there exist significant differences between human emotion in different weather conditions and road types. Participants’ engagement was higher in rainy and clear weather compared to cloudy weather. More-over, engagement was higher on city streets and highways compared to one-lane roads and two-lane highways.

Abstract:
Reversible lanes in Chicago’s Kennedy Expressway are an available infrastructure that can significantly improve traffic performance; however, a special focus on congestion management is required to improve their operation. This research project aims to evaluate and improve the operation of reversible lanes in the Kennedy Expressway. The Kennedy Expressway is a nearly 18-mile-long freeway in Chicago, Illinois, that connects in the southeast to northwest direction between the West Loop and O’Hare International Airport. There are two approximately 8-mile reversible lanes in the Kennedy Expressway’s median, where I-94 merges into I-90, and there are three entrance gates in each direction of this corridor. The purpose of the reversible lanes is to help the congested direction of the Kennedy Expressway increase its traffic flow and decrease the delay in the whole corridor. Currently, experts in a control location switch the direction of the reversible lanes two to three times per day by observing real-time traffic conditions captured by a traffic surveillance camera. In general, inbound gates are opened and outbound gates are closed around midnight because morning traffic is usually heavier toward the central city neighborhoods. In contrast, evening peak-hour traffic is usually heavier toward the outbound direction, so the direction of the reversible lanes is switched from inbound to outbound around noon. This study evaluates the Kennedy Expressway’s current reversing operation. Different indices are generated for the corridor to measure the reversible lanes’ performance, and a data-driven approach is selected to find the best time to start the operation. Subsequently, real-time and offline instruction for the operation of the reversible lanes is provided through employing deep learning and statistical techniques. In addition, an offline timetable is also provided through an optimization technique. Eventually, integration of the data-driven and optimization techniques results in the best practice operation of the reversible lanes.
