Computer vision is a rapidly growing field which aims to make computers 'see' as effectively as humans. In this book Dr Shapiro presents a new computer vision framework for interpreting time-varying imagery. This is an important task, since movement reveals valuable information about the environment. The fully-automated system operates on long, monocular image sequences containing multiple, independently-moving objects, and demonstrates the practical feasibility of recovering scene structure and motion in a bottom-up fashion. Real and synthetic examples are given throughout, with particular emphasis on image coding applications. Novel theory is derived in the context of the affine camera, a generalisation of the familiar scaled orthographic model. Analysis proceeds by tracking 'corner features' through successive frames and grouping the resulting trajectories into rigid objects using new clustering and outlier rejection techniques. The three-dimensional motion parameters are then compu

Ahmad Fardid (1910–94), the 'anti-Western' philosopher known to many as the Iranian Heidegger, became the self-proclaimed philosophical spokesperson for the Islamic Republic, famously coining the term 'Westoxication'. Using new materials about Fardid's intellectual biography and interviews with thirteen individuals, Ali Mirsepassi pieces together the striking story of Fardid's life and intellectual legacy. Each interview in turn sheds light on Iran's twentieth-century intellectual and political self-construction and highlights Fardid's important role and influence in the creation of Iranian modernity. The Fardid phenomenon was unique to the Iranian story, and yet contributed to a broader twentieth-century Heideggerian tradition that marked the political destiny of other countries under a similar ideological sway. Through these accounts, Mirsepassi cuts to the nerve of how deadly political 'authenticity movements' take hold of modern societies and spread their ideology. Combining a soci

Surveys are used extensively in psychology, sociology and business, as well as many other areas, but they are becoming increasingly difficult to conduct. Some segments of the population are hard to sample, some are hard to find, others are hard to persuade to participate in surveys, and still others are hard to interview. This book offers the first systematic look at the populations and settings that make surveys hard to conduct and at the methods researchers use to meet these challenges. It covers a wide range of populations (immigrants, persons with intellectual difficulties, and political extremists) and settings (war zones, homeless shelters) that offer special problems or present unusual challenges for surveys. The team of international contributors also addresses sampling strategies including methods such as respondent-driven sampling and examines data collection strategies including advertising and other methods for engaging otherwise difficult populations.

Numerical relativity has emerged as the key tool to model gravitational waves - recently detected for the first time - that are emitted when black holes or neutron stars collide. This book provides a pedagogical, accessible, and concise introduction to the subject. Relying heavily on analogies with Newtonian gravity, scalar fields and electromagnetic fields, it introduces key concepts of numerical relativity in a context familiar to readers without prior expertise in general relativity. Readers can explore these concepts by working through numerous exercises, and can see them 'in action' by experimenting with the accompanying Python sample codes, and so develop familiarity with many techniques commonly employed by publicly available numerical relativity codes. This is an attractive, student-friendly resource for short courses on numerical relativity, as well as providing supplementary reading for courses on general relativity and computational physics.

Just as the Bolshevik revolution defined the early politics of the 20th century, the transition from communist rule is the landmark event of its final years. In this important 1999 textbook, based on a wealth of references including interview and survey material, Stephen White offers a full, discriminating account of the dramatic process of change in what is still the world's largest country. After an early chapter examining the Gorbachev legacy, the book analyses the electoral process, the powerful presidency, and the intractable problem of economic reform. Later chapters cover social divisions, public opinion, and foreign policy, and a final chapter places the Russian experience within the wider context of democratisation. Clearly written, with numerous figures and illustrations, this book takes up Russia's story from the author's best-selling After Gorbachev to provide an unrivalled analysis of the politics of change in what is now the world's largest postcommunist society.
