Paper Abstract

We propose optical multichannel N4 correlator for implementation of the wavelet transform of two dimensional function, that yields four dimensional wavelet transform coefficients. We propose also the optical wavelet matched filter for two dimension pattern recognition. Advantage of this new band-pass matched filter is we can select image features to be enhanced by choosing the wavelet functions before the matched filtering. Experimental results are shown.
