Shimon Ullman focuses on the processes of high-level vision that deal with the interpretation and use of what is seen in the image. In this book, Shimon Ullman focuses on the processes of high-level vision that deal with the interpretation and use of what is seen in the image. In particular, he examines two major problems. The first, object recognition and classification, involves recognizing objects despite large variations in appearance caused by changes in viewing position, illumination, occlusion, and object shape. The second, visual cognition, involves the extraction of shape properties and spatial relations in the course of performing visual tasks such as object manipulation, planning movements in the environment, or interpreting graphical material such as diagrams, graphs and maps. The book first takes up object recognition and develops a novel approach to the recognition of three-dimensional objects. It then studies a number of related issues in high-level vision, including object classification, scene segmentation, and visual cognition. Using computational considerations discussed throughout the book, along with psychophysical and biological data, the final chapter proposes a model for the general flow of information in the visual cortex. Understanding vision is a key problem in the brain sciences, human cognition, and artificial intelligence. Because of the interdisciplinary nature of the theories developed in this work, High-Level Vision will be of interest to readers in all three of these fields.

With the growing strength of minority voices in recent decades has come much impassioned discussion of residential schools, the institutions where attendance by Native children was compulsory as recently as the 1960s. Former students have come forward in increasing numbers to describe the psychological and physical abuse they suffered in these schools, and many view the system as an experiment in cultural genocide. In this first comprehensive history of these institutions, J.R. Miller explores the motives of all three agents in the story. He looks at the separate experiences and agendas of the government officials who authorized the schools, the missionaries who taught in them, and the students who attended them. Starting with the foundations of residential schooling in seventeenth-century New France, Miller traces the modern version of the institution that was created in the 1880s, and, finally, describes the phasing-out of the schools in the 1960s. He looks at instruction, work and recreation, care and abuse, and the growing resistance to the system on the part of students and their families. Based on extensive interviews as well as archival research, Miller's history is particularly rich in Native accounts of the school system. This book is an absolute first in its comprehensive treatment of this subject. J.R. Miller has written a new chapter in the history of relations between indigenous and immigrant peoples in Canada. Co-winner of the 1996 Saskatchewan Book Award for nonfiction. Winner of the 1996 John Wesley Dafoe Foundation competition for Distinguished Writing by Canadians Named an 'Outstanding Book on the subject of human rights in North America' by the Gustavus Myer Center for the Study of Human Rights in North America.

Artificial Vision is a rapidly growing discipline, aiming to build computational models of the visual functionalities in humans, as well as machines that emulate them. Visual communication in itself involves a numberof challenging topics with a dramatic impact on contemporary culture where human-computer interaction and human dialogue play a more and more significant role. This state-of-the-art book brings together carefully selected review articles from world renowned researchers at the forefront of this exciting area. The contributions cover topics including image processing, computational geometry, optics, pattern recognition, and computer science. The book is divided into three sections. Part I covers active vision; Part II deals with the integration of visual with cognitive capabilities; and Part III concerns visual communication. Artificial Vision will be essential reading for students and researchers in image processing, vision, and computer science who want to grasp the current concepts and future directions of this challenging field. This state-of-the-art book brings together selected review articles and accounts of current projects from world-renowned researchers at the forefront of this exciting area. The contributions cover topics such as: - Psychology of perception - Image processing - Computational geometry - Visual knowledge representation and languages It is this truly multi-disciplinary approach that has produced successful theories and applications for the subject.

The Lord's Resistance Army is Africa's most persistent and notorious 'terrorist' group. Led by the mysterious Joseph Kony, it has committed a series of horrific human rights abuses, including massacres and mutilations. Since the mid 1980s, it has abducted tens of thousands of people, including large numbers of children forced to train as fighters. The IC in 2005 issued warrants for Kony and his top commanders, and the United States is backing a military campaign against the group. But the LRA survives, continuing to inspire both fascination and fear. Authoritative but provocative, The Lord's Resistance Army provides the most comprehensive analysis of the group available. From the roots of the violence to the oppressive responses of the Ugandan government and the failures of the international community, this collection looks at this most brutal of conflicts in fascinating depth, and includes a remarkable first-hand interview with Kony himself.

Computing is quickly making much of geometry intriguing not only for philosophers and mathematicians, but also for scientists and engineers. What is the core set of topics that a practitioner needs to study before embarking on the design and implementation of a geometric system in a specialized discipline? This book attempts to find the answer. Every programmer tackling a geometric computing problem encounters design decisions that need to be solved. This book reviews the geometric theory then applies it in an attempt to find that elusive "right" design.

Many approaches have been proposed to solve the problem of finding the optic flow field of an image sequence. Three major classes of optic flow computation techniques can discriminated (see for a good overview Beauchemin and Barron IBeauchemin19951): gradient based (or differential) methods; phase based (or frequency domain) methods; correlation based (or area) methods; feature point (or sparse data) tracking methods; In this chapter we compute the optic flow as a dense optic flow field with a multi scale differential method. The method, originally proposed by Florack and Nielsen [Florack1998a] is known as the Multiscale Optic Flow Constrain Equation (MOFCE). This is a scale space version of the well known computer vision implementation of the optic flow constraint equation, as originally proposed by Horn and Schunck [Horn1981]. This scale space variation, as usual, consists of the introduction of the aperture of the observation in the process. The application to stereo has been described by Maas et al. [Maas 1995a, Maas 1996a]. Of course, difficulties arise when structure emerges or disappears, such as with occlusion, cloud formation etc. Then knowledge is needed about the processes and objects involved. In this chapter we focus on the scale space approach to the local measurement of optic flow, as we may expect the visual front end to do. 17. 2 Motion detection with pairs of receptive fields As a biologically motivated start, we begin with discussing some neurophysiological findings in the visual system with respect to motion detection.
