对图像进行压缩，算术编码实现程序和仿真图象，给出基于 DCT 的图像压缩的 matlab 仿真结果(Image compression, arithmetic coding implementation program and simulation image, the image compression based on DCT matlab simulation results)

内容认证半脆弱水印算法的研究与实现,本程序实现图像的半脆弱水印，是基于DCT的算法，特别适合研究半脆弱水印的同志(Content authentication semi-fragile watermarking algorithm for Research and Implementation of, the procedures for the realization of the semi-fragile watermarking images is based on the DCT algorithm, especially appropriate to study the semi-fragile watermarking comrades)

两幅图像匹配，可以实现图片的缩放，旋转，灰度变换，压缩包内含有图片文件(picture matching)

通过使用LLE PCA两种方法相结合的思路，提高人脸识别的分别率(LLE PCA by using the idea of combining two methods to improve face recognition rate difference)

说明：  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.)

实图像的纹理特征提取，提取出的效果比较好，希望能够绑到有用的同学和人员(Real image texture feature extraction, the effect is better, hoping to be tied to useful classmates and personnel.)

此程序是应用于图形图像处理，基于matlab软件的二维高斯滤波算法实现。(This program is applied to graphics and image processing, based on MATLAB software two-dimensional Gauss filtering algorithm.)

用加密代码将文字隐藏在图片中，用解密代码将文字提取。c++(The text is hidden in the picture with encrypted code, and the text is extracted with decryption code.)

计算一幅图像的熵，matlab编程文件，任意读取一幅图像，计算信息熵(Calculate the entropy of an image)

说明：  NPCR and UNCI of image
