Extension of the joint transform correlator (JTC) operation to include complex reference image has been presented. Such amplitude and phase reference images are common when using a single harmonic (circular, radial, logarithmic, etc.) in correlation setups or when implementing composite filters. The analysis of an aspect view (tilt) invariant pattern recognition system, using logarithmic harmonics decomposition, JTC principles and composite filter techniques, is described followed by experimental results that can be obtained in real time.
