A study of moment invariants based on pattern recognition

Using moment invariants algorithm extract the eigenvector for the characteristics of the human ear. The algorithm is not subject to restrict on translation, rotation and the ratio of changes. Canny algorithm used for edge detection of human ear base on moment invariants. Experiment show that Canny algorithm can not miss the real edge and put the non-edge points as the edge point detection. It detects the edge points as possible in the actual center of the edge and Canny algorithm also inhibit the false edge response.
