Group and Crowd Behavior for Computer Vision provides a multidisciplinary perspective on how to solve the problem of group and crowd analysis and modeling, combining insights from the social sciences with technological ideas in computer vision and pattern recognition. The book answers many unresolved issues in group and crowd behavior, with Part One providing an introduction to the problems of analyzing groups and crowds that stresses that they should not be considered as completely diverse entities, but as an aggregation of people. Part Two focuses on features and representations with the aim of recognizing the presence of groups and crowds in image and video data. It discusses low level processing methods to individuate when and where a group or crowd is placed in the scene, spanning from the use of people detectors toward more ad-hoc strategies to individuate group and crowd formations. Part Three discusses methods for analyzing the behavior of groups and the crowd once they have been detected, showing how to extract semantic information, predicting/tracking the movement of a group, the formation or disaggregation of a group/crowd and the identification of different kinds of groups/crowds depending on their behavior. The final section focuses on identifying and promoting datasets for group/crowd analysis and modeling, presenting and discussing metrics for evaluating the pros and cons of the various models and methods. This book gives computer vision researcher techniques for segmentation and grouping, tracking and reasoning for solving group and crowd modeling and analysis, as well as more general problems in computer vision and machine learning. - Presents the first book to cover the topic of modeling and analysis of groups in computer vision - Discusses the topics of group and crowd modeling from a cross-disciplinary perspective, using social science anthropological theories translated into computer vision algorithms - Focuses on group and crowd analysis metrics - Discusses real industrial systems dealing with the problem of analyzing groups and crowds

In this fascinating book, New Yorker business columnist James Surowiecki explores a deceptively simple idea: Large groups of people are smarter than an elite few, no matter how brilliant—better at solving problems, fostering innovation, coming to wise decisions, even predicting the future. With boundless erudition and in delightfully clear prose, Surowiecki ranges across fields as diverse as popular culture, psychology, ant biology, behavioral economics, artificial intelligence, military history, and politics to show how this simple idea offers important lessons for how we live our lives, select our leaders, run our companies, and think about our world.

From jubilant sports fans celebrating a victory to angry political protestors, crowds create volatile situations that can all too often result in violence or property destruction. Preventing Crowd Violence offers a lucid examination of crowd behavior and of law enforcement tactics designed to deescalate tensions and promote cooperative interactions.

Crowd behavior is one of the most colorful but least understood forms of human social behavior. This volume is a major contribution to the field of collective behavior, with implications for social movement analysis.McPhail's critical assessment of the major theories of crowd behavior establishes that, whatever their particular limitations and strengths, all share a general and serious flaw: their explanations were developed without prior examination of the behaviors to be explained. Drawing on a wide range of empirical studies that include his own careful field work, the author offers a new characterization of temporary gatherings. He presents a life cycle of gatherings and a taxonomy of forms of collective behavior within gatherings, as well as combinations of these forms and gatherings into larger events, campaigns and waves. McPhail also develops a new explanation for various ways in which purposive actors construct collective actions.

This “disturbing yet fascinating” exploration of mass mania through the ages explains the biological and psychological roots of irrationality (Kirkus Reviews). From time immemorial, contagious narratives have spread through susceptible groups—with enormous, often disastrous, consequences. Inspired by Charles Mackay’s nineteenth-century classic Memoirs of Extraordinary Popular Delusions and the Madness of Crowds, neurologist and author William Bernstein examines mass delusion through the lens of current scientific research in The Delusions of Crowds. Bernstein tells the stories of dramatic religious and financial mania in western society over the last five hundred years—from the Anabaptist Madness of the 1530s to the dangerous End-Times beliefs that pervade today’s polarized America; and from the South Sea Bubble to the Enron scandal and dot com bubbles. Through Bernstein’s supple prose, the participants are as colorful as their “desire to improve one’s well-being in this life or the next.” Bernstein’s chronicles reveal the huge cost and alarming implications of mass mania. He observes that if we can absorb the history and biology of this all-too-human phenomenon, we can recognize it more readily in our own time, and avoid its frequently dire impact.

This volume brings together perspectives on social identity and peace psychology to explore the role that categorization plays in both conflict and peace-building. To do so, it draws leading scholars from across the world in a comprehensive exploration of social identity theory and its application to some of the world’s most pressing problems, such as intrastate conflict, uprising in the middle east, the refugee crisis, global warming, racism and peace building. A crucial theme of the volume is that social identity theory affects all of us, no matter whether we are currently in a state of conflict or one further along in the peace process. The volume is organized into two sections. Section 1 focuses on the development of social identity theory. Grounded in the pioneering work of Dr. Henri Tajfel, section 1 provides the reader with a historical background of the theory, as well as its current developments. Then, section 2 brings together a series of country case studies focusing on issues of identity across five continents. This section enables cross-cultural comparisons in terms of methodology and findings, and encourages the reader to identify general applications of identity to the understanding of peace as well as applications that may be more relevant in specific contexts. Taken together, these two sections provide a contemporary and diverse account of the state of social identity research in conflict situations and peace psychology today. It is evident that any account of peace requires an intricate understanding of identity both as a cause and consequence of conflict, as well as a potential resource to be harnessed in the promotion and maintenance of peace. Understanding Peace and Conflict Through Social Identity Theory: Contemporary Global Perspectives aims to help achieve such an understanding and as such is a valuable resource to those studying peace and conflict, psychologists, sociologists, anthropologists, public policy makers, and all those interested in the ways in which social identity impacts our world.
