Discrimination of color images and its electro-optical realization are described. In the hybrid system for color image discrimination, a 3-D vector color image is transformed into a 2-D vector image by projection onto a color plane, which is defined as complex plane. In the optical processing, correlation between two images is performed by mateched spatial filtering in which the filter is synthesized by the projected complex image of the reference pattern. The correlation peak is interfered with a refrence beam in order to detect the phase of the correlation result, because the result of the color image correlation is obtained as complex value. In this paper, the method of color image correlation and a technique for the optical implementation of a colorimage correlation are discribed, and the experimental result using a liquid crystal spatial light modulator is also included.
