Abstract :
In this paper, an improved method for detecting edge points is presented. We expatiated on the principle of Zernike moments and the method of sub pixel edge detection Based on Zernike moments. With deducing of the rotated Zernike moments, a new way to acquire the perpendicular distance from the center of the circular to the edge (l) is introduced in the criterion for detection of the edge points. Experimental results show that the improved sub pixel edge detection algorithm can detect the edge effectively and precisely. It has higher precision, integrality of detection and stronger robustness to noise. Besides, it also provides a valuable and promising reference for practical use of edge detection techniques.
