Paper Abstract

We demonstrate optical two-dimensional wavelet transform in an optical correlator and introduce optical wavelet matched filters that perform the shift invariant wavelet transform for feature enhancement and also the matching with library of templates for pattern recognition with improved discrimination capability and signal-to-noise ratio. Experimental results are shown.
