Abstract

We review recent work on rotation invariant pattern recognition. We briefly review results involving Circular harmonic filters, then describe some of our more recent research in this area. A pattern classification system that achieves rotation invariance by means of an optical rectangular-to-polar coordinate transformation is described, as well as a system using circular sampling. Experimental results using optical systems are presented for all those methods.
