Paper Abstract

We report a new experimental solution for implementing joint transform correlator (JTC) by subtracting modified Fourier spectrum described in [1], in which the authors used an additional contrast-reversed reference to enhance the expected correlation peaks for binary image processing. In our new solution, there is only a phase difference between the two reference images, and the amplitude of them, however, remain the same. Besides, our solution is generally available for the optical processing with binary images as well as with images of multiple gray levels.
