Paper Abstract

An optical wavelet processor for image feature analysis has been proposed using a JTC geometry. Haar wavelets are used in this study. Computer simulation studies are carried out to illustrate the principe of the processor using standard binary and gray-scale test images. An encoding technique has been discussed for the optical realization of the processor.
