DIGITAL COMPUTER SIMULATION OF VISUAL INFORMATION PROCESSING IN THE HUMAN BRAIN.

Abstract

A visual information processing system, based on selected aspects of human physiology, is simulated on the IBM 7094 digital computer through the use of over 50 test patterns. Monochromatic test patterns, represented by up to 2500 resolvable elements within a 50x50 array, are used to simulate static, foveal, monocular vision. Patterns are compared after scaling, rotation, and translation. The technique used for comparison which resembles the well known cross-correlation technique, is based upon the absolute-magnitude-of-the-difference of two functions; an algorithm is used for scaling and rotation. Similar and identical patterns are identified by means of empirically derived discrimination thresholds. (Author)
