In order to enhance the speed of image processing , the optic wavelet transform is applied to design of vision system based on the method of photoelectric hybrid implementation. Using the theory of optical information processing of 4f correlator, a library of wavelet function filters on the spatial light modulator with electro-address is constructed. It is achieved by computer programming in the spatial frequency domain, so the features of object can be extracted and recognized. The research results show the optic wavelet transform based vision system is reasonable and feasible. Optical information based image feature extraction will enhance the speed of vision information processing.
