| Abstract: | An optical wavelet transform for real-time image edge extraction system based on joint transform correlation ( JTC) was proposed in this paper. By taking advantage of the multiresolution characteristic of the wavelet function and by means of joint transform correlation, the Xcorr of the shrunk or zoomed wavelet generating function and image function by using Mexican-hat wavelet was implemented in real time. The experimental results are given. |
