Abstract

Circular harionic expansion of twodiiensional coiplex functions has proven to be a very useful tool for the design and experiiental realization of rotationally invariant pattern recognition correlation filters (1). Good practical results iay be obtained provided that the choice of the harionic order (nuiber of the ten of the expansion) and the polar coordinates origin taken are both optimized (2,3).
