摘要 开发了基于两个不同尺寸模板Zernike矩的新边缘检测算子.首先利用小模板3*3尺寸的像素级Zernike矩算子快速检测出所有可能边缘点;然后利用大模板7*7尺寸的亚像素级Zernike矩算子重新精确定位边缘.检验结果表明,本方法定位精度为亚像素级,且算法运行时间为0.14s.新算子具有运算速度快、定位精度高的优点. A new edge detection operator using two Zernike moments with different mask sizes is developed. Firstly, all probable edge points were detected quickly with using Zernike moments operator with mask size of 3 ＊ 3. Then a Zemike moments operator with mask size of 7 ＊ 7 was used to relocate the edge with subpixel accuracy. Testing result shows that the location accuracy of proposed method is closed to subpixel level, and the running time is 0. 14 s. Thus the proposed edge operator has advantages of both short running time and high location accuracy.
