CONTROLLED-INTENSITY DETECTION PEAKS IN A BINARY JOINT TRANSFORM CORRELATOR

In multiobject pattern recognition the height of the correlation peaks should be controlled when the power spectrum of a joint transform cor relator is binarized. In this paper a method to predetermine the value of detection peaks is demonstrated. The technique is based on a frequ ency-variant threshold in order to remove the intraclass terms and on a suitable factor to normalize the binary joint power spectrum. Digita l simulations and experimental hybrid implementation of this method we re carried out.
