Abstract

The fringe-adjusted joint transform correlator (JTC) technique has been found to yield substantially better correlation performance than alternate JTC techniques. Since the fringe-adjusted JTC (FJTC) is sensitive to scale and rotation variations, a synthetic discriminant function (SDF) based FJTC was proposed to realize scale and rotation invariant pattern recognition system via computer simulation. In this paper, optoelectronic implementation of the scale and rotation invariant pattern recognition using SDF based FJTC has been tested for both binary and gray level images. The experimental results obtained are in close agreement with the simulation results obtained earlier.
