Paper Abstract

The optical wavelet circular harmonic function minimum average correlation energy (WCHF- MACE) filter is proposed. The proposed WCHF-MACE filter uses the wavelet transformed image by Mexican-hat wavelet function for circular harmonic function and the multiple harmonic components of circular harmonic function are used for MACE filter synthesis. The proposed filter has good discrimination compared with the conventional circular harmonic function filter and conventional circular harmonic MACE filter about the limited rotated images. And the filter is made of the type of optical wavelet matched filter (WMF), so that the proposed filter can use the conventional 4f correlator.
