摘要

A new approach towards solving the pattern recognition problems in hybrid optical-digital 4F correlators is suggested. The method is based on that during the realization of the recognition procedure in the optical-digital correlator instead of real amplitude or amplitude-phase objects incoming on its input there is proposed to use synthesized phase (SP) objects unambiguously related to it. SP-objects represent object-dependent phase distributions calculated with application of iterative Fourier-transform (IFT) algorithm. Replacement of real objects with SP-objects allows to unify the shape (form) of correlation signals and so to formalize the procedure of choice of recognition attributes for objects of arbitrary classes. The modified recognition procedure in optical-digital correlators is presented, the influence of noises and distortions in the structure of input object upon characteristics of cross-correlation signal of corresponding SP-objects is studied. Numerical simulation results are presented.
