Paper Abstract

We define one kind of new correlation, i.e. random phase correlation, which based on the Random Fourier Transform (RFT). An optical pattern recognition system, random phase filtering, is given according to random phase correlation. Furthermore its electro-optical setup is given for the application in image recognition. By the numerical simulation on computer, when the, we have found the proposed random phase filter can recognize the small change of object image and has higher recognition capability comparing of other three conventional correlators, the classical marched filter, the phase-only filter and the pure phase correlator.
