ResumoWe introduce optical wavelet matched filters that perform the wavelet transforms for edge enhancement and perform correlations between the wavelet coefficients for shift-invariant pattern recognition. These new bandpass matched filters show improved discrimination capability with respect to the conventional matched spatial filter and improved signal-to-noise ratio with respect to the phase-only matched filter.
