图象平滑锐化，清华学生写的。值得一看，他代码的行文都非常的清晰，不愧是重点大学的学生啊-smoothing image sharpening, Tsinghua students wrote it. An eye-catcher, he reads the code are very clear, and is indeed the focus of university students ah. .

本文主要讨论获得图片后如何提取其边界信息，首先利用图像灰度均匀化解决了对比度不清晰的问题，然后利用高斯滤波法对图片进行滤波去噪，进而利用Canny算法实现边缘检测提取边界，该方法与Matlab自带的求边界方法有明显的提高，为利用Matlab程序求图像分形维数提供了更精确的前提。-This article focuses on how to get the image to extract the boundary information, the first to use to the gray
