Apparent surface color is more than color appearance

Abstract

New picture storage and display technologies have drawn increasing attention to a very old (and difficult) scientific problem, human perception of complex visual patterns. One strategy, 'color appearance' research, involves application of sensory concepts (e.g., contrast and adaptation) and experimental methods (e.g., complete color matching) to slightly more complex stimuli than the simple disk-of-light-in-a-dark- surround of traditional color sensation research. Recent progress in the field of image analysis indicates that the color appearance approach cannot capture the processes responsible for visual analysis of images of real scenes. Perceptual competence in image analysis requires use of spatial structure that is not exploited by the quasi-local analyses of sensory adaptation and contrast. These distinctions are easily illustrated with simple demonstrations. The concepts of image analysis have inspired a number of recent quantitative studies of human surface color perception. Work along these lines should develop a knowledge base useful in practical problems of human image manipulation
