Abstract
The joint-transform correlator operation has been extended to include complex reference images. Such amplitude and phase images are common when single harmonic images (circular, radial, logarithmic, etc.) are used in correlation setups. The analysis of a rotation-invariant pattern-recognition system using joint-transform correlator principles is described, followed by experimental results that can be obtained in real time.
