Paper Abstract

The composite wavelet-matched filter is a nonlinear combination of the wavelet-matched filters that yields correlation between the wavelet transforms of the input image and a combination of edge enhanced training images. The filter is designed with an iteration algorithm to ensure the desired output peak value for each training image. The filter is optically implemented with a phase mostly modulation liquid crystal television and a photographic amplitude modulation mask. This filter shows the best performance compared with the phase-only composite filter and the conventional composite filter. Experimental results are shown.
