Abstract

We investigate a binary encoding technique to represent grayscale nonlinear joint transform correlators. We show that the joint power spectrum can be binary encoded to represent gray-scale nonlinear joint transform correlators. The threshold function is computed analytically in terms of the power spectra of the input signal and the reference signal. Computer simulations of the correlation tests for various degrees of nonlinear transformation of the joint power spectrum are presented.
