Paper Abstract

A new algorithm of opto-'electronic hybrid pattern recognition, which is based on the theory of sequency spectrum analysis, is presented. In this method, a series of variable blackS-white ratio gratings realized with an array CCD is employed as spatial filters with which the recognized pattern is filtered. The algorthm is implemented on a hybrid system of opto-electronics and computer, and also the hybrid algorithm of Fast Walsh Transform is realized.
