Abstract
We describe a pattern recognition processor based on a new optimal (2) (chi) filtering method that is designed to localize a target with unkn own gray levels appearing on a random background. This processor consi sts of preprocessing of the analyzed image followed by correlations wi th binary masks. (C) 1997 Optical Society of America.
