摘要： 介绍了两种矩的理论,然后根据建立的四参数边缘模型,分别利用两种矩的性质推导出边缘参数与矩之间的关系,利用矩得到图像边缘参数,最后由边缘参数确定图像边缘.两种矩方法得到的边缘的边缘定位精度都已达到亚像素级.

关键词: 空间矩, 边缘检测, 亚像素, Zernike矩, 边缘定位

Abstract: The theories of spatial moment and Zernike moment are presented. An edge model with four parameters has been built and the relations between edge parameters and the two moments are analyzed respectively. The values of edge parameters are calculated to get the edge image. The method can locate edges to sub-pixel.

Key words: sub-pixel, edge location, spatial moment, Zernike moment, edge detection
