Paper Abstract

An optical WCHF-SDF (wavelet circular harmonic function synthetic discriminant function) filter is proposed. The proposed WCHF-SDF filter is synthesized by 2nd order harmonics of the four different wavelet transformed patterns by Haar wavelet function. This filter has full rotation and limited scale invariant properties. The scale invariant range can be increased by using more training patterns.
