This book provides an introduction to human visual perception suitable for readers studying or working in the fields of computer graphics and visualization, cognitive science, and visual neuroscience. It focuses on how computer graphics images are generated, rather than solely on the organization of the visual system itself; therefore, the text pro

This book presents theories and techniques for perception of textures by computer. Texture is a homogeneous visual pattern that we perceive in surfaces of objects such as textiles, tree barks or stones. Texture analysis is one of the first important steps in computer vision since texture provides important cues to recognize real-world objects. A major part of the book is devoted to two-dimensional analysis of texture patterns by extracting statistical and structural features. It also deals with the shape-from-texture problem which addresses recovery of the three-dimensional surface shapes based on the geometry of projection of the surface texture to the image plane. Perception is still largely mysterious. Realizing a computer vision system that can work in the real world requires more research and ex periment. Capability of textural perception is a key component. We hope this book will contribute to the advancement of computer vision toward robust, useful systems. vVe would like to express our appreciation to Professor Takeo Kanade at Carnegie Mellon University for his encouragement and help in writing this book; to the members of Computer Vision Section at Electrotechni cal Laboratory for providing an excellent research environment; and to Carl W. Harris at Kluwer Academic Publishers for his help in preparing the manuscript.

The visual analysis of surface shape from texture and surface contour is treated within a computational framework. The aim of this study is to determine valid constraints that are sufficient to allow surface orientation and distance (up to a multiplicative constant) to be computed from the image of surface texture and of surface contours. The report is in three parts. Part I consists of a review of major theories of surface perception, a discussion of vision as computation and of the nature in which three-dimensional information is manifest in the image, and a study of the representation of local surface orientation. Part II reconisiders the familiar 'texture gradient'. Part III examines our preception of surface contours. It is shown that surface contours are strong sources of information about local surface shape.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do. The basic assumption is that vision depends on the eye which is connected to the brain. The author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision -- and what this book is about.

The visual perception of texture is introduced as a research problem important, in itself, but important also as an entrance into the broader and little understood area of complex pattern perception. Definitions of texture, both from a substantive and an abstract standpoint, are presented and followed by discussions of: (1) the information carried in textures and (2) the possible functions of texture perception in visually controlled behavior. Then a review of laboratory and field studies is presented, followed by a discussion of directions for future research. A functional theory of pattern perception is assumed, in which the processing of substantive information in optical patterns is emphasized. The application of man's natural visual capacities is proposed for scientific imagery analysis. Techniques are suggested for presenting the imagery in an ecologically relevant context of substantive analysis and description. (Author).
