This is an attempt to apply the concepts and techniques of information theory to the problems of visual perception. The informational concept of redundancy comes in for a good deal of attention with regard to the understanding of phenomena of visual perception, and a demonstration of its nature in this area is presented. The analysis employed by the author also permits him to present informational and statistical descriptions of a good many classical concepts from the area of vision, including the historically most important Gestalt perceptual principles.
