Abstract

A new class of composite filters is proposed. This class of filters can be used in optical correlator based recognition systems. It introduces a novel approach for rotation and scale invariant systems. Also it can be used to improve power throughput without sacrificing the signal-to-ratio in optical correlators based on complex matched filters.
