N2 - Optical correlation schemes based on a matched filter containing a single Mellin radial or logarithmic harmonic of an object can be used to provide 2-D or 1-D scale invariant pattern recognition. The performance of these harmonic filters, as well as the performance of the conventional matched filter, was investigated. The response of the filters to various distortion parameters was studied along with a quantitative comparison between the various filters, using several performance criteria. In addition, the noise response of the above filters is analyzed. The noise considered was an additive white noise to the input plane, characterized by a single parameter σ, varied between 0 to 3 times the maximum input intensity. The analysis and results apply also to the joint transform correlator configuration.
