改程序主要功能是抠图，使用键盘鼠标操作，实现对图像的切割及边缘的检测。-The main function of the change program matting, use the keyboard and mouse operations, cutting and edge detection image.

数字图像中尖端点检测，采用了Harris算法，然后运用susan算法思想进行改进，使用时后面if程序的一些条件要适当改一下-Digital image edge detection, using the Harris algorithm, and then use thought susan algorithm is improved when you use the latter procedure if a number of conditions to change what should
