摘要

摘要

En 中文
A voting scheme for the construction of composite filter for distortion-invariant optical pattern recognition is addressed. The motivation is the limited modulation capability of the spatial light modulator (SLM) which is incorporated as a design constraint in the form of majority-granted nonlinearity. The technique is simple, and less computationally extensive nevertheless resulting in a robust enough SLM-realizable distortion-invariant correlator. Simulation results are presented for rotation invariant character recognition, which shows better correlation discrimination and robust recognition for threshold detectors.
