Perceptual constancy

"Perceptual Constancy examines a group of long-standing problems in the field of perception and provides a review of the fundamentals of the problems and their solutions. Experts in several different fields - including computational vision, physiology, neuro-psychology, psychophysics, and comparative psychology - present their approaches to one of the fundamental problems of perception: How does the brain extract a stable world from an ever-changing retinal input? How do we achieve color constancy despite changes in the wavelength content of daylight? How do we recognize objects from different viewpoints? And how do we know the sizes of those objects?"--BOOK JACKET.
