此程序实现matlab GUI上的图像处理，包括图像加噪（高斯，椒盐等），以及图像均衡、二值，以及多种锐化方法，图像亮度调节，另外还有图像保存、对比功能。(This procedure on matlab GUI image processing, including image plus noise (Gaussian, salt and pepper, etc.), and a graphic equalizer, two values, as well as a variety of sharpening method, image brightness adjustment, in addition to save the image, the contrast function.)

抽取子图像: 通过一个随机混沌标签序列从原图像中抽取 对子图像加密:小波变换 ,在高频部分加密 重构原图，把加密好的子图像重新放回到原图像中 (from sub-images : a random chaotic sequence label from the original image from a tradition image encryption : wavelet transform, the high-frequency part of remodeling the maximum encryption, encrypted good son to re-up images back to the original image)

自己编写的数学形态学膨胀和腐蚀的matlab算法 适用于二值和灰度图象 (I have written mathematical morphology and corrosion expansion matlab algorithm for binary and gray-scale image)

压缩感知中利用增广拉格朗日方程解最小稀疏正则化的恢复算法(DAL solves the dual problem of (1) via the augmented Lagrangian method (see Bertsekas 82). It uses the analytic expression (and its derivatives) of the following soft-thresholding operation， which can be computed for L1 and grouped L1 (and many other) sparsity inducing regularizers. If you are interested in our algorithm please find more details in our technical report or in my talk at Optimization for Machine Learning Workshop (NIPS 2009).)

该资料中的程序实现的是图像压缩，供初学者学习。(The data of the program implementation is the image compression, for beginners to learn.)
