Abstract:

Two methods for identifying the revolving image on the computer are put forward: the matched transform correlator and the joint transform correlator.Comparison of the analog data of the two algorithms shows that the joint transform correlator algorithm is better in recognizing the target object.And simulation experiments show that computer simulation recognition is superior to the real optical pattern recognition in succinctness and significance.

Key words: matched transform correlator;joint transform correlator;union power spectrum;duplicate conjugate;rotation angle in the plane
