说明：  C++编写的进行图像边缘检测处理的基本算法程序，一共有四种算法可以选择，可以自定义图像大小和处理模式，略加修改后也可以应用在Windows窗口模式下。
(prepared by the image edge detection algorithm to deal with the basic procedures, a total of four algorithms to choose from, You can define the size and image processing mode, slightly modified later can be used in the Windows mode.)
