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.

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.

A unique, easy-to-use guide to radar tracking and Kalman filtering This book presents the first truly accessible treatment of radar tracking; Kalman, Swerling, and Bayes filters for linear and nonlinear ballistic and satellite tracking systems; and the voltage-processing methods (Givens, Householder, and Gram-Schmidt) for least-squares filtering to correct for computer round-off errors. Tracking and Kalman Filtering Made Easy emphasizes the physical and geometric aspects of radar filters as well as the beauty and simplicity of their mathematics. An abundance of design equations, procedures, and curves allows readers to design tracking filters quickly and test their performance using only a pocket calculator! The text incorporates problems and solutions, figures and photographs, and astonishingly simple derivations for various filters. It tackles problems involving clutter returns, redundant target detections, inconsistent data, track-start and track-drop rules, data association, matched filtering, tracking with chirp waveform, and more. The book also covers useful techniques such as the moving target detector (MTD) clutter rejection technique. All explanations are given in clear and simple terms, including: * The voltage-processing approach to least-squares filtering * The correlation between such procedures as discrete orthogonal Legendre polynomial (DOLP) and voltage processing * The mathematical sameness of tracking and estimation problems on the one hand, and sidelobe canceling and adaptive array processing on the other * The massively parallel systolic array sidelobe canceler processor * Important computational accuracy issues * An appended comparison between the Kalman and the Swerling filters, written by Dr. Peter Swerling Tracking and Kalman Filtering Made Easy is invaluable for engineers, scientists, and mathematicians involved in tracking filter design. Its straightforward approach makes it an excellent textbook for senior-undergraduate and first-year graduate courses.
