RS攻击M程序,用于检测图像是否经过LSB密写(RS attack M procedures for detecting whether the image after LSB steganalysis)

说明：  基于python-opencv的图像匹配代码，包含了SIFT、SURF、AKAZE、ORB方法。43-48行修改图像路径，74-81修改匹配方法。(dev: python3.6+opencv_python==3.4.2+opencv-contrib-python==3.4.2)

包括基于SIFTGPU的sift特征提取，sift匹配，基于ransac误匹配点剔除等(SIFTGPU based sift feature extraction, sift matching, mismatching points based ransac removed, etc.)

自适应滤波器LMS算法包括SIMULINK模型及S函数的编写(LMS adaptive filter algorithm, including the preparation of the SIMULINK model and S function)

基于基元共生矩阵的纹理特征提取。通过5个基本的方格来检测图像并生成图像的基元共生矩阵，并从矩阵中提取其纹理特征信息。(Texton occurrence matrix based texture feature extraction)

图像边缘检测，实现了几种边缘检测算法，像Roberts，Sobel，Prewitt，Canny等(Edge detection, edge detection algorithm to achieve several, such as Roberts, Sobel, Prewitt, Canny, etc.)

说明：  国外一个博士写的图像复原的源码 ，基于自适应的正则化的全变分图像复原，源码内有作者的主页，相应文章可以下载。代码测试，可用，效果不错 ，做这方面的同志可以下来看看 (Dr. written by a foreign source image restoration based on adaptive regularization total variation image restoration, source inside of the home page, the corresponding articles can be downloaded. Code test, available, good results, so this could be down to see Comrade)
