Paper Abstract

Invariant correlation filters application allows to achieve correlation peak invariance in the presence of distortions of input object in comparison with reference object. One of the most perspective correlation filters are Linear Phase Coefficient Composite Filters (LPCC filter). These filters provide good recognition results in the case of geometrically distorted contoured binary input objects. LPCC filter realization in 4-f correlator demands formation of corresponding impulse response of the optical system. The results of synthesis and realization of LPCC filters as holographic diffraction elements are presented in the paper.
