Abstract
A multiple circular harmonic (CH) expansion filter has been developed to rotation invariant pattern recognition with the joint transform correlator. By correctly choosing the number and orders of circular harmonic expansions of the object, the mostly similary patterns, which have the propability to get false detection when just single CH expansion is considered, can be discriminated.
