说明：  组稀疏表示，可用于信号的稀疏表示，内有多个demo(GroupSparseBox_V2, it can be usef in singal sparse model)

基本图像处理用C++的实现。包括平移旋转翻转边缘提取canny算子等(The basic image processing with C + +.)

说明：  扩散映射置乱与超混沌系统组合图像加密算法 扩散映射置乱与超混沌系统组合图像加密算法(Combi ned i mage encryption a lgor ithm ba sed on di ffusi on mapped disorder and hyperchaoti c system s)

说明：  IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)

自己编写的粒子群优化算法,以计算一个函数的值作为测试,达到了良好的精度(The particle swarm optimization algorithm written by ourselves is designed to calculate the value of a function as a test, and good precision is achieved.)

直方图均衡化，局部直方图均衡化，直方图匹配，中值滤波，(histgram equalization,histogram matching)

这是一个可以计算图片分形维数的软件，可用于图片分形维数计算(Fractal dimension of a picture can be calculated a small software)

说明：  一种彩色图像的边缘检测算法，检测效果非常好，它是对Canny算法的改进，定位好，相应标准高，检测率高，误检率低(a kind of edge detection algorithm.The algoritlun employs amultpassprocessing approach that re}novesnoisefrom theRGB componentswith apre-filter, with the color edge detector then based on an extended gray scale edge gradient tern plate detector.)

将灰度图像装换成rgb图像的Matlab实现(transfer the gray image to rgb one)
