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

Net criticism that establishes the principles and foundation for a collaborative, global new media culture. According to media critic Geert Lovink, the Internet is being closed off by corporations and governments intent on creating a business and information environment free of dissent. Calling himself a radical media pragmatist, Lovink envisions an Internet culture that goes beyond the engineering culture that spawned it to bring humanities, user groups, social movements, nongovernmental organizations (NGOs), artists, and cultural critics into the core of Internet development. In Dark Fiber, Lovink combines aesthetic and ethical concerns and issues of navigation and usability without ever losing sight of the cultural and economic agendas of those who control hardware, software, content, design, and delivery. He examines the unwarranted faith of the cyber-libertarians in the ability of market forces to create a decentralized, accessible communication system. He studies the inner dynamics of hackers' groups, Internet activists, and artists, seeking to understand the social laws of online life. Finally, he calls for the injection of political and economic competence into the community of freedom-loving cyber-citizens, to wrest the Internet from corporate and state control. The topics include the erosion of email, bandwidth for all, the rise and fall of dot-com mania, techno-mysticism, sustainable social networks, the fight for a public Internet time standard, the strategies of Internet activists, mailing list culture, and collaborative text filtering. Stressing the importance of intercultural collaboration, Lovink includes reports from Albania, where NGOs and artists use new media to combat the country's poverty and isolation; from Taiwan, where the September 1999 earthquake highlighted the cultural politics of the Internet; and from Delhi, where a new media center explores free software, public access, and Hindi interfaces.

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.

There is a great deal of practice, discussion, and publication about strategy, but surprisingly little investigation of the processes by which strategies actually form in organizations. Henry Mintzberg, one of the world's leading thinkers and writers on management, has over several decades examined the processes by which strategies have formed in a variety of contexts, and this book collects together his findings. Defining realized strategy - the strategy an organization has actually pursued - as a pattern in a stream of actions, this investigation tracked strategies in organizations over long periods of time, usually three or four decades, and in one case, a century and a half. This revealed the patterns by which strategies form and change in organizations, the interplay of 'deliberate' with 'emergent' strategies, and the relationships between leadership, organization, and environment in the strategy formation process. An introductory chapter considers the term strategy, and the various ways it has been and can be used, and then introduces the studies. These are reported in the next ten chapters, with descriptions and conclusions about the strategies were formed over time, and how they combined to establish periods in the history of the organization. These studies range across business (six studies), government (two studies), an architectural firm, and a university, as well as one professor in that university. They include U.S. strategy in Vietnam (1950-1973), Volkswagenwrk (1937-1972), and the National Film Board of Canada (1939-1975). The final chapter, entitled 'Toward a General Theory of Strategy Formation', weaves these findings together in two themes. First is strategy formation in different forms of organization: Strategic Planning in the Machine Organization, Strategic Visioning in the Entrepreneurial Organization, Strategic Learning in the Adhocracy Organization, and Strategic Venturing in the Professional Organization. The second theme considers stages in the formation of strategies, from Initiation through Development to Renewal.
