说明：  使用Matlab GUI界面编写的图像锐化程序，实现的功能包括：图像的打开、保存、使用“sobel算子”、“prewitt算子”、“roberts算子”、“log算子”、“canny算子”、“zero-cross算子”、“laplacian算子”对图像进行锐化等。
(Written in Matlab GUI interface using image sharpening procedures, functions include: the image open, save, use the " sobel operator" , " prewitt operator" , " roberts operator" , " log operator" , " canny operator child " ," zero-cross operator " ," laplacian operator " for image sharpening.)
