matlab图像处理函数集，系统总结matlab在图像处理中的图像输入、处理（滤波、增强）、分析（边缘检测）、输出等方面的内容(matlabmatlab)

这是一个基于超像素算法的分割小软件，可以用于图像的分割，但是没有语义。使用者如果用于商用，要联系软件中的作者(This is a small software based on super-pixel algorithm, which can be used for image segmentation, but without semantics. Users for commercial use should contact the authors in the software.)

本例程通过matlab编写，显示一个GUI。在GUI中将输入到程序中的数据进行绘图。本例程能够实时进行绘图，并且可以将数据进行显示。同时还可以将输入到程序中的数据进行保存。在GUI中设置有控制开关，能够通过点击开关，将数据保存在不同的文本中便于后续处理使用。(This routine is written by matlab and displays a GUI. The data input into the program is drawn in the GUI. This routine can be plotted in real time and data can be displayed. At the same time, the data input into the program can also be saved. A control switch is set in the GUI, and the data can be saved in different texts by clicking the switch to facilitate subsequent processing.)

使用盲数字水印实现DWT ，数字水印的嵌入和提取，小波变换(Using blind digital watermarking to implement DWT)

海杂波背景下的分形特征，目标检测，赫斯特指数(HEST = wfbmesti(X) returns a row vector HEST which contains three estimates of the fractal index H of the signal X supposed to come from a fractional Brownian motion of parameter H.)

实现对一幅灰度和彩色图像作的离散余弦变换,选择适当的DCT系数阈值对其进行DCT反变换.(The realization of a piece of gray and color images for the discrete cosine transform, select the appropriate thresholds for DCT coefficients of its inverse transform DCT.)

图像经过双随机处理和分数阶傅里叶变换，可以达到加密解密的功能，且对密钥敏感性较强。(The image undergoes double random processing and fractional Fourier transform, which can achieve the function of encryption and decryption, and has strong sensitivity to the key.)

稀疏低秩去噪的MATLAB代码，包括OMP算法与KSVD算法(Sparse low rank denoising MATLAB codes, including OMP algorithm and KSVD algorithm)

说明：  CS的一些重构算法包括OMP，somp,romp,SAMP，CoSaMp，GPSR等等其中还包括了小波变换，dct变换等等(compressive sensing)
