Abstract

Design of matched filters containing a single radial harmonic of an object are shown to provide shift and scale invariant correlations. The theory of the expansion, using Mellin radial harmonics, is analyzed and tested experimentally for some binary optical targets. Cross-correlation pattern recognition in the presence of scale and shift invariances has been successfully demonstrated. Two approaches for improving t he correlation peak are presented.
