Paper Abstract

Conventional methods of optical pattern recognition suffer from the requirement of high resolution recording materials and distortion sensitivity. In some recent publications1-3 a new, general procedure was introduced that may be employed for generating spatial filters with reduced resolution requirements. Partial- and complete rotation-invariance was demonstrated in computer simulations with phase- and bipolar amplitude-filters, respectively.
