其余混沌的数字图像置乱。该算法利用混沌对初值的敏感性，算法是想简单。(The rest of Chaos Digital Image Scrambling. The algorithm using the sensitivity of chaos to the initial value, the algorithm is to simple.)

ROF模型的matlab代码，两个文件：main.m和ROFdenoise.m文件，前者调用后一个文件，后一个文件为rof去噪算法代码。(Matlab code of the ROF model, the two files: the s main.m and ROFdenoise.m file call the former a file after a file rof denoising algorithm code. )

正太分布的贝叶斯参数估计，写的很详细，很有用(This code is based on the Bayesian threshold segmentation, very useful)

此程序主要是检测黄色区域（用于人脸识别） 所用摄像头为USB320X240RGB的 原理： 先利用颜色找出符合条件的大面积黄 再利用模板闭运算补充连通与 再利用XY轴上连同域的寻找 标出人脸(The procedure is to detect the yellow area (for recognition) camera for USB320X240RGB used the principle: first, to identify qualified by the color yellow and then use a large area of the template to add connectivity and re-closing operation axis together with the domain using the search XY Face marked)

这是经典的复杂网络的小世界模型和均匀网络模型，你可以画出度分布图。(this is a cassic complex network of small-world model aniform model, distribution of degrees can be drawn.)
