Paper Abstract

An optoelectronic correlator with variable discrimination capability is applied to the recognition of polychromatic patterns. Dual non-linear correlation and RGB multichannel processing are used to solve four different situations: a recognition system with high discrimination for both shape and color; high discrimination for shape and tolerance to color variations; the vice versa, tolerance to shape variations and high discrimination for color; and finally, tolerance to shape and color variations simultaneously.
