Application of the wavelet transform to pattern correlation recognition

Optical pattern recognition has extensive actual applications.The usually adopted technology is to detect the correlate intension between detection goal image and standard image.We combine effectively wavelet transform with the joint transform correlator(JTC),and have analyzed how to carry out correlation discrimination with wavelet transform,and dedicated the theoretical method and the structural block diagram that realizes image correlation identification.Finally the wavelet type,wavelet filter approach,wavelet filter perform and so on have been introduced.
