Video Tracking provides a comprehensive treatment of the fundamental aspects of algorithm and application development for the task of estimating, over time, the position of objects of interest seen through cameras. Starting from the general problem definition and a review of existing and emerging video tracking applications, the book discusses popular methods, such as those based on correlation and gradient-descent. Using practical examples, the reader is introduced to the advantages and limitations of deterministic approaches, and is then guided toward more advanced video tracking solutions, such as those based on the Bayes’ recursive framework and on Random Finite Sets. Key features: Discusses the design choices and implementation issues required to turn the underlying mathematical models into a real-world effective tracking systems. Provides block diagrams and simil-code implementation of the algorithms. Reviews methods to evaluate the performance of video trackers – this is identified as a major problem by end-users. The book aims to help researchers and practitioners develop techniques and solutions based on the potential of video tracking applications. The design methodologies discussed throughout the book provide guidelines for developers in the industry working on vision-based applications. The book may also serve as a reference for engineering and computer science graduate students involved in vision, robotics, human-computer interaction, smart environments and virtual reality programmes

Background subtraction is a widely used concept for detection of moving objects in videos. In the last two decades there has been a lot of development in designing algorithms for background subtraction, as well as wide use of these algorithms in various important applications, such as visual surveillance, sports video analysis, motion capture, etc. Various statistical approaches have been proposed to model scene backgrounds. The concept of background subtraction also has been extended to detect objects from videos captured from moving cameras. This book reviews the concept and practice of background subtraction. We discuss several traditional statistical background subtraction models, including the widely used parametric Gaussian mixture models and non-parametric models. We also discuss the issue of shadow suppression, which is essential for human motion analysis applications. This book discusses approaches and tradeoffs for background maintenance. This book also reviews many of the recent developments in background subtraction paradigm. Recent advances in developing algorithms for background subtraction from moving cameras are described, including motion-compensation-based approaches and motion-segmentation-based approaches.

Sensor Data Fusion is the process of combining incomplete and imperfect pieces of mutually complementary sensor information in such a way that a better understanding of an underlying real-world phenomenon is achieved. Typically, this insight is either unobtainable otherwise or a fusion result exceeds what can be produced from a single sensor output in accuracy, reliability, or cost. This book provides an introduction Sensor Data Fusion, as an information technology as well as a branch of engineering science and informatics. Part I presents a coherent methodological framework, thus providing the prerequisites for discussing selected applications in Part II of the book. The presentation mirrors the author's views on the subject and emphasizes his own contributions to the development of particular aspects. With some delay, Sensor Data Fusion is likely to develop along lines similar to the evolution of another modern key technology whose origin is in the military domain, the Internet. It is the author's firm conviction that until now, scientists and engineers have only scratched the surface of the vast range of opportunities for research, engineering, and product development that still waits to be explored: the Internet of the Sensors.

Drug courts offer offenders an intensive court-based treatment program as an alternative to the normal adjudication process. Begun in 1989, they have since spread dramatically throughout the United States. In this interdisciplinary examination of the expanding movement, a distinguished panel of legal practitioners and academics offers theoretical assessments and on-site empirical analyses of the workings of various courts in the United States, along with detailed comparisons and contrasts with related developments in Britain. Practitioners, politicians, and academics alike acknowledge the profound impact drug courts have had on the American criminal justice system. From a range of disciplinary perspectives, contributors to this volume seek to make sense of this important judicial innovation. While addressing a range of questions, Drug Courts also aims to achieve a careful balance between focused empirical studies and broader theoretical analyses of the same phenomenon. The volume maintains an analytical concentration on drug courts and on the important practical, philosophical, and jurisprudential consequences of this unique form of therapeutic jurisprudence. Drug courts depart from the practices and procedures of typical criminal courts. Prosecutors and defense counsel play much-reduced roles. Often lawyers are not even present during regular drug court sessions. Instead, the main courtroom drama is between the judge and client, both of whom speak openly and freely in the drug court setting. Often accompanying the client is a treatment provider who advises the judge and reviews the client's progress in treatment. Court sessions are characterized by expressive and sometimes tearful testimonies about the recovery process, and are often punctuated with applause from those in attendance. Taken together, the chapters provide a variety of perspectives on drug courts, and extend our knowledge of the birth and evolution of a new movement. Drug Courts is an essential reference for courses in criminology, the sociology of drugs and deviance, and the philosophy of law and punishment.

The world of cinematography has changed more in the last few years than it has since it has in 1929, when sound recording was introduced. New technology, new tools and new methods have revolutionized the art and craft of telling stories visually. While some aspects of visual language, lighting and color are eternal, shooting methods, workflow and cameras have changed radically. Even experienced film artists have a need to update and review new methods and equipment. These change affect not only the director of photography but also the director, the camera assistants, gaffers, and digital imaging technicians. Cinematography: Theory and Practice covers both the artistry and craftsmanship of cinematography and visual storytelling. Few art forms are as tied to their tools and technology as is cinematography. Take your mastery of these new tools, techniques, and roles to the next level with this cutting-edge roadmap from author and filmmaker Blain Brown. Whether you are a student of filmmaking, just breaking into the business, currently working in the industry and looking to move up to the next level, or an experienced professional who wants to update their knowledge of tools and techniques, this book provides both a basic introduction to these issues as well as more advanced and in-depth coverage of the subject. The companion website features additional material, including lighting demonstrations, basic methods of lighting, using diffusion and other topics. Topics Include: Visual language Visual storytelling Continuity and coverage Cameras and digital sensors Exposure techniques for film and video Color in-depth Understanding digital images Waveform monitors, vectorscopes, and test charts Using linear, gamma, and log encoded video Image control and grading on the set The tools and basics of film lighting ASC-CDL, ACES and other new methods Optics and focus Camera movement Set operations Green screen, high speed and other topics
