Features

  • Ties together image generation and the resulting perceptual phenomena
  • Includes topics seldom seen in introductory perception texts, such as the perception of material properties, illumination, the perception of pictorial space, image statistics, perception and action, and spatial cognition
  • Emphasizes visual performance, with coverage of biological mechanisms in specific situations to aid in the understanding of practical issues
  • Each chapter includes a section on Issues specific to computer graphics and ends with Suggestions for further reading

Summary

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 provides a more direct tie between image generation and the resulting perceptual phenomena. It covers such topics as the perception of material properties, illumination, the perception of pictorial space, image statistics, perception and action, and spatial cognition.

Editorial Reviews

This is a fabulous book written by the right people, and if I had to pick only three books for my desk, this would be one of them.
—Peter Shirley, author of Fundamentals of Computer Graphics

This is the first book on perception to build on the need to understand how images are formed in order to understand how they are perceived and used. The discussions of applications to computer graphics are the icing on the cake of a broad and often deep treatment of the ever-growing science of human visual perception.
—Daniel Kersten, Department of Psychology, University of Minnesota

Finally, here is a book that offers a thorough introduction to visual perception specifically geared toward the graphics practitioner. It should be required reading for anyone serious about computer graphics.
—Alexei A. Efros, School of Computer Science, Carnegie Mellon University

It matches basic vision texts in coverage and adds the unique point of view of production: how would you create this scene? It is an excellent resource and new source of ideas about how vision works and how computer graphics can best take advantage of the properties of the human visual system.
—Patrick Cavanagh, Université Paris Descartes and Harvard University
