Abstract

In this paper, the lnr-(theta) coordinate transform method is used in the joint transform correlator (JTC) so that the rotation and scale variant pattern can be recognized. The distortion invariant JTC is implemented in real time by using the LCLVs. Initial experimental results are given in this paper.
