for edge detection(linear detection as road) in radar images we can use the morphology technique. here i am coding fo morphology process to detect the linear feature of an image.

人机交互小功能，画曲线，改变颜色，生成矩阵，随机与固定的，退出，改变线型(Human-Computer Interaction small features, drawing curves, changing the color, generating matrix, random and fixed, from the change of linear)

说明：  基于非负矩阵分解（NMF）的人脸特征提取算法，NMF基本思想是找到一个线性子空间W，使的构成子空间的基本图像的像素点都是正值，而且人脸图像在子空间上的投影系数也是正数(Non-negative Matrix Factorization (NMF) of facial feature extraction algorithm, NMF basic idea is to find a linear sub-space W, so that the composition of sub-space of the basic image pixels are positive, and face image in the sub-space projection coefficient is positive)

DSGE模型程序，用于校准分析，希望大家能够喜欢。(DSGE for calibration)

Block-interleaver/deinterleaver according to the IEEE 802.11-2007 Defined by two step-permutation : The first permutation ensures that adjacent coded bits are mapped onto nonadjacent sub-carriers. The second ensures that adjacent coded bits are mapped alternately onto less and more significant bits of the constellation and, thereby, long runs of low reliability (LSB) bits are avoided. Tested and works well

使用有限元方法求解漫射方程,其中所需要的三维有限元网格来自netgen软件。压缩包中包含了网格数据文件和源代码。代码运行之前首先要注意修改源代码中的网格文件的存放路径。(solve the diffusion equation with finite method,the mesh which is used in it is generated by netgen。A matlab source code and a mesh file is include in it. The mesh file path should be set before running the sourcecode.)
