Abstract

Often one is confronted with recognizing objects of given shape but arbitrary orientation. Matched filters then fail to work. To overcome this obstacle circularly symmetric filters have been designed. The basic principle of such orientation independent filters (OIF) can be interpreted as a phase compensation filter approach. They turn out to be highly sensitive to any shape variations. These filters are easy to produce for many applications.
