The Interpretation of Visual Motion


Book Description

This book uses the methodology of artificial intelligence to investigate the phenomena of visual motion perception: how the visual system constructs descriptions of the environment in terms of objects, their three-dimensional shape, and their motion through space, on the basis of the changing image that reaches the eye. The author has analyzed the computations performed in the course of visual motion analysis. Workable schemes able to perform certain tasks performed by the visual system have been constructed and used as vehicles for investigating the problems faced by the visual system and its methods for solving them.Two major problems are treated: first, the correspondence problem, which concerns the identification of image elements that represent the same object at different times, thereby maintaining the perceptual identity of the object in motion or in change. The second problem is the three-dimensional interpretation of the changing image once a correspondence has been established.The author's computational approach to visual theory makes the work unique, and it should be of interest to psychologists working in visual perception and readers interested in cognitive studies in general, as well as computer scientists interested in machine vision, theoretical neurophysiologists, and philosophers of science.




Aspects of Motion Perception


Book Description

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.




An Introduction to the Visual System


Book Description

Building on the successful formula of the first edition, Martin Tovée offers a concise but detailed account of how the visual system is organised and functions to produce visual perception. He takes his readers from first principles; the structure and function of the eye and what happens when light enters, to how we see and process images, recognise patterns and faces, and through to the most recent discoveries in molecular genetics and brain imaging, and how they have uncovered a host of new advances in our understanding of how visual information is processed within the brain. Incorporating new material throughout, including almost 50 new images, every chapter has been updated to include the latest research, and culminates in helpful key points, which summarise the lessons learnt. This book is an invaluable course text for students within the fields of psychology, neuroscience, biology and physiology.




Foundations of Vision


Book Description

Designed for students, scientists and engineers interested in learning about the core ideas of vision science, this volume brings together the broad range of data and theory accumulated in this field.




Perception of Space and Motion


Book Description

During the past 25 years, the field of space and motion perception has rapidly advanced. Once thought to be distinct perceptual modes, space and motion are now thought to be closely linked. Perception of Space andMotion provides a comprehensive review of perception and vision research literature, including new developments in the use of sound and touch in perceiving space and motion. Other topics include the perception of structure from motion, spatial layout,and information obtained in static and dynamic stimulation.Spatial layoutStructure from motionInformation on static and dynamic stimulation (visual, acoustic, and haptic)




Seeing Motion


Book Description

Die avancierten Kunstschaffenden haben seit jeher innovativen Erfindungen aus dem Bereich der Naturwissenschaften zu den Themen Licht und Perspektive für ihre Darstellungen eingesetzt und dabei nachweislich sogenannte Sehapparate verwendet. Seit Anfang der zwanziger Jahre des 20. Jahrhunderts setzten sich Künstler wie Marcel Duchamp mit Scheinbewegungen auseinander. Aufbauend auf diesen frühen Ideen und künstlerischen Experimenten kam besonders die Scheinkontur durch die Beschäftigung mit Scheinräumlichkeit zu neuem Interesse, vor allem vonseiten der Vertreter der kinetischen Kunst und der Op-Art. Seeing Motion gibt einen Überblick entlang einer historischen Linie, die sich zwischen den Theorien der experimentellen visuellen Wahrnehmungsforschung (Hermann Helmholtz, Ernst Mach, Sigmund Exner, Wilhelm Stern, Vittorio Benussi, Max Wertheim, George Stratton, Ivo Kohler) bis hin zur apparativen Kunst (Alfons Schilling) sowie zur elektronisch-digitalen Kunst (Jeffrey Shaw, Peter Weibel) abzeichnet.







Alhacen's Theory of Visual Perception


Book Description

Sometime between 1028 and 1038, Ibn al-Haytham completed his monumental optical synthesis, Kitab al-Manazir ("Book of Optics"). By no later than 1200, and perhaps somewhat earlier, this treatise appeared in Latin under the title De aspectibus. In that form it was attributed to a certain "Alhacen." These differences in title and authorial designation are indicative of the profound differences between the two versions, Arabic and Latin, of the treatise. In many ways, in fact, they can be regarded not simply as different versions of the same work, but as different works in their own right. Accordingly, the Arab author, Ibn al-Haytham, and his Latin incarnation, Alhacen, represent two distinct, sometimes even conflicting, interpretive voices. And the same holds for their respective texts. To complicate matters, "Alhacen" does not represent a single interpretive voice. There were at least two translators at work on the Latin text, one of them adhering faithfully to the Arabic original, the other content with distilling, even paraphrasing, the Arabic original. Consequently, the Latin text presents not one, but at least two faces to the reader. This two-volume critical edition represents fourteen years of work on Dr. Smith's part. Awarded the 2001 J. F. Lewis Award.




Persistence and Change


Book Description

First published in 1985. This series of volumes is dedicated to furthering the development of psychology as a branch of ecological science. In its broadest sense, ecology is a multidisciplinary approach to the study of living systems, their environments. and the reciprocity that has evolved between the two. The purpose of this series is to form a useful collection, a resource, for people who wish to learn about ecological psychology and for those who wish to contribute to its development. The series will include original research, collected papers, reports of conferences and symposia, theoretical monographs, technical handbooks, and works from the many disciplines relevant to ecological psychology. This volume holds proceedings papers.




Modeling Psychophysical Data in R


Book Description

Many of the commonly used methods for modeling and fitting psychophysical data are special cases of statistical procedures of great power and generality, notably the Generalized Linear Model (GLM). This book illustrates how to fit data from a variety of psychophysical paradigms using modern statistical methods and the statistical language R. The paradigms include signal detection theory, psychometric function fitting, classification images and more. In two chapters, recently developed methods for scaling appearance, maximum likelihood difference scaling and maximum likelihood conjoint measurement are examined. The authors also consider the application of mixed-effects models to psychophysical data. R is an open-source programming language that is widely used by statisticians and is seeing enormous growth in its application to data in all fields. It is interactive, containing many powerful facilities for optimization, model evaluation, model selection, and graphical display of data. The reader who fits data in R can readily make use of these methods. The researcher who uses R to fit and model his data has access to most recently developed statistical methods. This book does not assume that the reader is familiar with R, and a little experience with any programming language is all that is needed to appreciate this book. There are large numbers of examples of R in the text and the source code for all examples is available in an R package MPDiR available through R. Kenneth Knoblauch is a researcher in the Department of Integrative Neurosciences in Inserm Unit 846, The Stem Cell and Brain Research Institute and associated with the University Claude Bernard, Lyon 1, in France. Laurence T. Maloney is Professor of Psychology and Neural Science at New York University. His research focusses on applications of mathematical models to perception, motor control and decision making.
