Originated from a small workshop on the question of how image motion is processed under natural conditions that was held in 1997 at the Institute of Advanced Studies of the Australian National University in Canberra."--Pref.
In six parts, this book considers the extent to which computational, neural, and ecological constraints have shaped the mechanisms underlying motion vision: - Early Motion Vision - Motion Signals for Local and Global Analysis - Optical Flow Patterns - Motion Vision in Action - Neural Coding of Motion - Motion in Natural Environments Each topic is introduced by a keynote chapter which is accompanied by several companion articles. Written by an international group of experts in neurobiology, psychophysics, animal behaviour, machine vision, and robotics, the book is designed to explore as comprehensively as possible the present state of knowledge concerning the principal factors that have guided the evolution of motion vision.
This comprehensive book deals with motion estimation for autonomous systems from a biological, algorithmic and digital perspective. An algorithm, which is based on the optical flow constraint equation, is described in detail.
Dynamic Neural Field Theory for Motion Perception provides a new theoretical framework that permits a systematic analysis of the dynamic properties of motion perception. This framework uses dynamic neural fields as a key mathematical concept. The author demonstrates how neural fields can be applied for the analysis of perceptual phenomena and its underlying neural processes. Also, similar principles form a basis for the design of computer vision systems as well as the design of artificially behaving systems. The book discusses in detail the application of this theoretical approach to motion perception and will be of great interest to researchers in vision science, psychophysics, and biological visual systems.
International Series of Monographs in Experimental Psychology, Volume 16: Aspects of Motion Perception details the fundamental concepts of the visual system perception of motion. The text first details the various findings about illusory and veridical motions along with the theories conceptualized from those findings. Next, the selection covers the research that studies the reliability and validity of the theories about motion perception. The book also discusses the importance of two-component model of motion perception. The last chapter covers the characteristics of the status of perceptual experiences. The book will be of great use to behavioral scientists and biologists. Ophthalmologists will also benefit from the text.
Complex and crucially important, the senses collect the massive amount of information we need to navigate daily life, and serve as a filter between our inner selves and the larger world. But the science of how the senses work has been little understood—until now. New research is rapidly uncovering fascinating insights into how the brain processes sensory information. It’s not simply a matter of the brain controlling the senses; the senses actually stimulate brain development. For example, the brain’s sound-processing centers mature properly only when sound impulses trigger them to do so—which is why cochlear implants are best used before the age of three. Brain Sense reveals this and a wealth of findings on how the brain and senses interact, as it examines each of the five major senses: touch, smell, taste, vision, and hearing. With eloquent writing and gripping stories, the author deploys a rare gift for explaining complex scientific ideas in a way that is clear and comprehensible. She introduces the scientists at the forefront of “brain sense” studies—neurologists, brain mappers, biochemists, physicians, cognitive psychologists, and others—as well as real-life people who are contributing to the research and benefiting from its practical applications, such as haptic devices to assist people who have lost limbs or rehabilitative software for those who have suffered impairments to their motion vision. You’ll find new research that explains: • Why placebos work by changing the way the brain processes pain • How humans respond to pheromones in the same manner as other animals • How taste is highly influenced by expectations of taste • Why color significantly aids the ability to remember an object • How the capacity for language is already at work in newborn babies • What happens in the brain to produce sensory experiences such as déjà vu and phantom limb pain • And much more Expansive and enlightening, Brain Sense shows us that the brain is both flexible and variable, and the reality that we construct based on inputs gathered from the senses differs from person to person. It sheds a much-needed light on the elusive workings of the extraordinary human brain.
From August 24-29, 1980 the international "Symposium on the Study of Motion Perception; Recent Developments and Applications", sponsored by NATO and organized by the editors of this book, was held in Veldhoven, the Netherlands. The meeting was attended by about eighty scholars, including psychologists, neurologists, physicists and other scientists, from fourteen different countries. During the symposium some fifty research papers were presented and a series of tutorial review papers were read and discussed. The research presentations have been published in a special issue of the international journal of psychonomics "Acta Psychologica" (Vol. 48, 1981). The present book is a compilation of the tutorial papers. The tutorials were arranged around early versions of the chapters now appearing in this book. The long discussions at the Veldhoven tutorial sessions resulted in extensive revisions of the texts prior to this publication. Unfortunately this led to a delay in publication, but we feel that this was justified by a greater depth of understanding which, in our opinion, has significantly increased the quality of the book. As they now stand, the chapters cover most of the issues relevant to the study of motion perception. Also they clearly reflect the intensive exchange of knowledge that took place during the symposium. As such we think that this book can be used both as an advanced text for students and scientists alike and as a comprehensive reference source.
This book on autonomous road-following vehicles brings together twenty years of innovation in the field. The book uniquely details an approach to real-time machine vision for the understanding of dynamic scenes, viewed from a moving platform that begins with spatio-temporal representations of motion for hypothesized objects whose parameters are adjusted by well-known prediction error feedback and recursive estimation techniques.
Motion processing is an essential piece of the complex brain machinery that allows us to reconstruct the 3D layout of objects in the environment, to break camouflage, to perform scene segmentation, to estimate the ego movement, and to control our action. Although motion perception and its neural basis have been a topic of intensive research and modeling the last two decades, recent experimental evidences have stressed the dynamical aspects of motion integration and segmentation. This book presents the most recent approaches that have changed our view of biological motion processing. These new experimental evidences call for new models emphasizing the collective dynamics of large population of neurons rather than the properties of separate individual filters. Chapters will stress how the dynamics of motion processing can be used as a general approach to understand the brain dynamics itself.
