Abstract
We present a method to detect patterns in defocused scenes by means of a joint transform correlator. We describe analytically the correlatio n plane, and we also introduce an original procedure to recognize the target by postprocessing the correlation plane. The performance of the methodology when the defocused images are corrupted by additive noise is also considered. (C) 1997 Optical Society of America.
