Paper Abstract

Optical pattern recognition has always offered the advantages of high speed and parallel processing with the basic linear system operations of Fourier transformation and correlation being its hallmark. Recent years have considerably broadened this repertoire of operations to include optically-generated features, distortion-invariant correlators, space-variant processors, optically-produced local operators, increased use of digital post-processing al-gorithms, more extensive tests on large multi-class image databases, various real-time architectures, etc.
