Book Description
The automation of visual inspection is becoming more and more important in modern industry as a consistent, reliable means of judging the quality of raw materials and manufactured goods . The Machine Vision Handbook equips the reader with the practical details required to engineer integrated mechanical-optical-electronic-software systems. Machine vision is first set in the context of basic information on light, natural vision, colour sensing and optics. The physical apparatus required for mechanized image capture – lenses, cameras, scanners and light sources – are discussed followed by detailed treatment of various image-processing methods including an introduction to the QT image processing system. QT is unique to this book, and provides an example of a practical machine vision system along with extensive libraries of useful commands, functions and images which can be implemented by the reader. The main text of the book is completed by studies of a wide variety of applications of machine vision in inspecting and handling different types of object.

Book Description
A radically new perspective on human vision is emerging. Groundbreaking research by evolutionary scientist and neurobiologist Mark Changizi is driving a revolution in our understanding of human vision. In asking why we see the way we do, Changizi overturns existing beliefs and provides new answers to age-old questions. Why do our eyes face forward? While binocular vision was helpful to our primate ancestors, its importance for 3-D vision is exaggerated. Squirrels jump from branch to branch just fine with sideways-facing eyes and many athletes, including Hockey Hall of Famer Frank McGee, play with only one eye. HINT: We evolved in a highly leafy environment. Why do we see in color, when most other mammals do not? Its not because it helped our ancestors find ripe fruit. Our color vision has evolved to be extremely sensitive to specific sets of color changes. HINT: Primates with color vision, like us, are the only ones who have areas of bare skin. Why do we see optical illusions? Its not the result of glitches in our visual system. Optical illusions can be traced back to the same specific property of vision. HINT: We are able to catch a ball coming at us much more effectively than we should given the speed at which our brains process visual input. Why do we absorb information so readily by reading? Its not because weve evolved to read; evolutionarily, reading and writing are recent developments. HINT: Language is designed to exploit skills weve refined over tens of millions of years. In The Vision Revolution, Changizi details the conclusions of his innovative fieldwork and their mind-blowing implications for our understanding not just of human vision, but of the way we interact with the world in which we live.

Book Description
An engaging introduction to the science of vision that offers a coherent account of vision based on general information processing principles In this accessible and engaging introduction to modern vision science, James Stone uses visual illusions to explore how the brain sees the world. Understanding vision, Stone argues, is not simply a question of knowing which neurons respond to particular visual features, but also requires a computational theory of vision. Stone draws together results from David Marr's computational framework, Barlow's efficient coding hypothesis, Bayesian inference, Shannon's information theory, and signal processing to construct a coherent account of vision that explains not only how the brain is fooled by particular visual illusions, but also why any biological or computer vision system should also be fooled by these illusions. This short text includes chapters on the eye and its evolution, how and why visual neurons from different species encode the retinal image in the same way, how information theory explains color aftereffects, how different visual cues provide depth information, how the imperfect visual information received by the eye and brain can be rescued by Bayesian inference, how different brain regions process visual information, and the bizarre perceptual consequences that result from damage to these brain regions. The tutorial style emphasizes key conceptual insights, rather than mathematical details, making the book accessible to the nonscientist and suitable for undergraduate or postgraduate study.

Book Description
Available again, an influential book that offers a framework for understanding visual perception and considers fundamental questions about the brain and its functions. David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood. Researchers from a range of brain and cognitive sciences have long valued Marr's creativity, intellectual power, and ability to integrate insights and data from neuroscience, psychology, and computation. This MIT Press edition makes Marr's influential work available to a new generation of students and scientists. In Marr's framework, the process of vision constructs a set of representations, starting from a description of the input image and culminating with a description of three-dimensional objects in the surrounding environment. A central theme, and one that has had far-reaching influence in both neuroscience and cognitive science, is the notion of different levels of analysis—in Marr's framework, the computational level, the algorithmic level, and the hardware implementation level. Now, thirty years later, the main problems that occupied Marr remain fundamental open problems in the study of perception. Vision provides inspiration for the continuing efforts to integrate knowledge from cognition and computation to understand vision and the brain.

Book Description
This book considers computer vision to be an integral part of the artificial intelligence system. The core of the book is an analysis of possible approaches to the creation of artificial vision systems, which simulate human visual perception. Much attention is paid to the latest achievements in visual psychology and physiology, the description of the functional and structural organization of the human perception mechanism, the peculiarities of artistic perception and the expression of reality. Computer vision models based on these data are investigated. They include the processes of external data analysis, internal environmental model synthesis, and the generating of behavioristic responses based on external and internal models comparison. Computer vision system evolution resulting from environmental effects is also considered. A unique feature of this book is the authors' use of black and white, and colour prints of traditional and contemporary Russian art to illustrate their principal theses. In doing so, they introduce the reader to a particularly Russian view of the world.

Book Description
Why do we need two eyes? Why are all cats grey at night and appear to move faster the day? Why is the sky blue and the setting sun red? This book explains the multifaceted nature of perception, and discusses the mysteries of vision. It provides readers with experiments to help them discover optical illusions and the features of their own perception. Illusions of Seeing begins with a discussion on the essence of light and its perception to the human eye. It presents a comprehensive overview of the basic laws of human perception as well as the fundamentals of good gestalt. Subsequent chapters discuss geometric-optical illusions; the perception of form, brightness, and translucency and their interaction with each other; ambiguous perception, color vision, spatial vision. The book ends with a discussion of the perception of motion and its interaction with color, form, and spatial depth with a full chapter devoted to illusions in our everyday life. Consider this your travel guide in the marvelous world of sight, to experience a completely individual way to understand and improve your own perception. Illusions of Seeing will be of interest to psychologists, physicists, biologists, and undergraduate and graduate students within the field of cognitive psychology.

Book Description
This book, first published in 1979, is 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.
