Paper Abstract

A wavelet feature based generalized fringe adjusted joint transform correlator (FAJTC) has been proposed to improve the performance of FAJTC in the presence of noise in the object scene. A simple technique has been combined with the above approach for eliminating the zero-order and intra- class correlation signals from correlation output.
