Holographic filter based on Linear Phase Coefficient Composite Filter for image recognition using 4-F correlator

Distortion invariant correlation filters application allows correlation image recognition robust to distortions of target objects such as rotation and scaling etc. One of the most perspective is Linear Phase Coefficient Composite Filter (LPCCF) which can be realized in coherent 4-F correlator as computer generated holographic filter. Given paper introduces different aspects of LPCCF realization in 4-F correlator.
