Abstract
One of the most important problems in optical pattern recognition by c orrelation is the a appearance of sidelobes in the correlation plane, which causes false alarms. We present a method that eliminate sidelobe s of up to a given height if certain conditions are satisfied. The met hod can be applied to any generalized synthetic discriminant function filter and is capable of rejecting lateral peaks that are even higher than the central correlation. Satisfactory results were obtained in bo th computer simulations and optical implementation.
