Performance of the optical wavelet matched filter

Optical wavelet matched filter performs the wavelet transforms for edge enhancement and correlations between the wavelet transform coefficients in a single step for shift invariant pattern recognition. The performance of the wavelet matched filter depends on the scale factor s. A systematic study and comparison on the light efficiency, discrimination capability and robustness to noise is made for the wavelet matched filter, the matched spatial filter and the phase-only matched filter.© (1993) COPYRIGHT SPIE--The International Society for Optical Engineering.
