Abstract

The joint transform correlation can be optimized by subtracting the constant terms (Fourier transform power spectra) in the filter plane. Computer simulations for three approaches to optimization have been performed and have shown that the contrast of joint transform power spectrum can be maximized to produce optimal correlation signal.
