Based on the Zernike moments, a high-speed Zernike moments edge operator based on 9×9 masks is developed.Firstly, the calculation steps of Zernike moments masks are derived,and then two 9×9 masks of the new edge operator are given.Two different images are chosen for the new operator testing:one is the original artificial binary image, and the other is the fuzzy image after 5 times of smoothing.The results show that the new operator has strong edge refining ability, and the edge detecting accurac...
