Abstract:Faced object morphological correlation based on JTC computer simulation is presented.Two kinds of modified morphological correlation algorithm that are based on bit-representation decomposition are presented.The gray-scale image is decomposed into a set of binary slices in the bit-representation decomposition.In the first algorithm,the edge of each pair of slices is detected.In the second algorithm,the joint power spectrum of each pair is binarized or the summation of the joint power spectrum of these pairs is binarized.Modified two dimention correlation peak and spectrum image is gived.Computer-simulation results indicate that the modified algorithm can improve the discrimination capabilities with respect to the high similarity gray-scale images.关键词:联合变换相关器;数学形态学;光学模式识别Key words:joint transform correlator;mathematical morphology;optical pattern recognition
