Abstract

Optical correlation schemes based on circular or radial harmonics have been recently suggested for performing pattern recognition in the presence of rotated or scaled versions of the object. Those schemes, however, are based on using a single harmonic at one time. In this paper we present two approaches that overcome this restriction.
