Abstract

Optical correlation has traditionally processed monochromatic gray-scale images. This paper develops a new encoding mechanism that uses the chromaticity of the input signal. It is then not only possible to detect different colored objects, but the system is also invariant to changes in the brightness of the lighting, including variations across the object.
