使用空间矩算法实现图像亚像素边缘检测，程序精度能达到0.1个像素级别-Spatial moment algorithm to image sub-pixel edge detection

本程序在Matlab环境下完成，用于边缘的亚像素定位，精度达到0.1-0.2个像素，内含源代码及说明-This program completed in the Matlab environment. It is used for sub-pixel edge positioning and the accuracy of the method is 0.1-0.2 pixels. Including the source code and descr iption.

传统的边缘检测算法只能定位到像素级，不能得到精确的结果，亚像素是对像素进一步细分，是结果更精确-Traditional edge detection algorithm can only target the pixel level, you can not get an accurate result, the pixel sub-pixel is further broken down, as a result of more accurate
