对图像进行细化，本实验的细化对象是一组指纹二值图。(Image refinement, the refinement of the experimental object is a set of fingerprint binary image.)

图像灰度化处理、图像柔和处理、图像锐化处理(Grayscale image processing, image gentle processing, image sharpening)

脆弱水印的matlab实现 脆弱水印的matlab实现(Fragile watermarking matlab implementation)

纯contourlet变换，已对工具包进行了修改，使之在分解重构时能显示子带系数。(Pure contourlet transformation toolkit has been modified so that when displayed in the decomposition and reconstruction sub-band coefficients.)

用matlab实验的进行均值滤波的改进函数(Experiments carried out using matlab mean filter to improve the function of)

Split Bregman算法 各向同性，各向异性 图像去噪(Split Bregman algorithm TV model image denoising)

说明：  布谷鸟搜索（Cuckoo Search，缩写 CS），也叫杜鹃搜索，是由剑桥大学杨新社（音译自：Xin-She Yang）教授和S.戴布（S.Deb）于2009年提出的一种新兴启发算法。(Cuckoo search, also known as cuckoo search, is a new heuristic algorithm proposed by Professor Xin She Yang of Cambridge University and S. DEB in 2009.)

基于压缩感知的图像加密算法，稀疏基用的是小波，重构用的是OMP(Compressed sensing image encryption algorithm)

snake算法演示程序，相当不错的一个matlab程序(snake algorithm demo program, a pretty good program matlab)

小波域稀疏表示，正交匹配追踪算法压缩感知重建(wavelet transform Compressive sensing)
