title: Optimal X(2) filtering method and application to targets and backgrounds with random correlated gray levels.
abstract: We describe a pattern recognition processor based on a new optimal x(2) filtering method that is designed to localize a target with unknown gray levels appearing on a random background. This processor consists of preprocessing of the analyzed image followed by correlations with binary masks.
