这是SPAMS的原始代码，是稀疏表示的重要工具箱~(This is SPAMS original code, is an important toolbox sparse representation)

根据超限像素平滑定义用 Matlab 自编写超限像素平滑法滤波(Super pixel smooth)

基于变换域的可逆数字水印系统的设计，是本人的毕业设计，基于整数小波变换的嵌入，加上gui界面，记得自己把自己想用的载体图像放到文件夹中。(Design reversible transform domain watermarking system based on my graduation project is based on integer wavelet transform embedded, plus gui interface, the carrier image into your own folder.)

说明：  最简单的进行两图像的加减和异或，同或，运算。(The simplest operation is to add and subtract two images, and to add and subtract two images.)

说明：  使用pca方法对图像进行特征提取，对训练集的20个人的共一百张人脸进行训练，使用adaboost算法生成强分类器，可以对测试集的人脸图片进行识别，且识别率较高(The PCA method is used to extract the features of the image, and the training is carried out for a total of 100 faces of 20 people in the training set. The AdaBoost algorithm is used to generate a strong classifier, which can recognize the face images in the test set with a high recognition rate)

说明：  滤波是将信号中特定波段频率滤除的操作，是抑制和防止干扰的一项重要措施，滤波分为经典滤波和现代滤波。(Filtering is the operation of filtering out the specific band frequency of the signal, which is an important measure to suppress and prevent interference. Filtering is divided into classical filtering and modern filtering.)

说明：  基于sift特征提取的图像配准的几个案例(Several cases of image registration based on SIFT feature extraction)

使用IDL编程来实现打开BMP，TIFF，IMG，JPEG，PNG和其他图像，实现缩放，缩放，平移，图像增强，平滑，边缘检测(Using IDL programming bmp, tiff, img, jpeg, png and other images to achieve open and zoom in, zoom, pan, image enhancement, smoothing, edge detection)

本实验要求编写一个计算压缩-解压缩图像的均方根误差、均方信噪比的程序。该程序是一个通用程序。编写程序产生图示的结果。使用上面的保真度准则程序计算可视信息的损失特性。(Prepared in this experiment, a calculation of compression- decompression of the root-mean-square error of image, mean square signal to noise ratio of the procedure. The procedure is a common procedure. Picture shows the preparation of the results of procedures. The use of the above criteria for the fidelity of calculated loss characteristics of visual information.)

计算两幅图像之间的交叉熵，自己编的比较简单和大家分享。(Calculate the cross-entropy between the two images, their own series is relatively simple and to share.)
