用于分别从四个方向提取图形图像的纹理特征(For texture feature graphic images were extracted four directions)

基于matlab的图像加密，直接运行就行(Image encryption based on matlab)

this is a program for image compression

java 图形算法实现源代码，有坐标放大缩小。(java graphics algorithm source code, coordinates Zooming.)

递归与分治演算Gray码，Gray码是一个长度为2N的序列(Recursive partition calculus with the Gray code, Gray code is a sequence of length 2N)

傅里叶描述子用来描述和识别图像中有边缘的物体形状，本程序基于MATLAB，测试可用(Fourier descriptor is to analyze and identify the important objects in the shape of one of the methods. The use of polygon-based curve near Continuous Fourier transform method like Fourier descriptors, and through the main direction of the shape to eliminate the border from Phase of the influence of starting point, define a new rotation, translation and scale invariance of the normalized Fourier Ye descriptor.)

基于Hilbert变换的相位差测量法分析及改进 (Based on the analysis phase measurement and improvement of the Hilbert transform)

IDL实现modis数据的辐射校正 修改文件路径即可用(IDL achieve modis radition correction Modify the file path can be used)

用vibe算法提取动态背景的前景信息，背景为白色(Vibe algorithm is used to extract foreground information of the dynamic background, the background is white)

图像拼接算法中尺度不变特征转换（sift）源码。经过本人测试修改完全可用，对matlab还不怎么熟练的新手有很大帮助。(Image mosaic algorithm scale invariant feature transform (sift) source. After I test change is totally available, not on how skilled novice matlab great help.)
