这是关于遥感图像的地物边界提取与填充，是在matlab中实现的，减少了很多繁琐的代码，简单实用-extraction of Feature in digital image on matlab .This is a mathod for the Remote sensing image processing which is very useful.With this method we can Reduce a lot of tedious code.

p_m模型，各向异性扩散函数的matlab程序，用于对图像进行去噪及边界提取-p_m model, anisotropic diffusion function matlab program for image denoising and edge detection

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
