数字水印算法实现（matlab程序包），包含有DCT水印嵌入算法，DWT水印嵌入算法，以及水印攻击和性能测试程序。参考价值极大(digital watermarking algorithm (Matlab package), including a watermark embedded DCT algorithm, DWT algorithm embedded watermark, watermark and attack and performance testing procedures. Great value)

这是一些关于特征配准和融合的一些文章，对做这一方面的应该有所借鉴(which is a characteristic of fusion and registration of some articles, so in this respect there should be some reference)

说明：  基于YCbCr椭圆模型，使用肤色进行人脸检测(use the skin color to detect human-face base on YCbCr modal)

OpenGL高级编程与可视化系统开发（高级编程篇）的随书源码-4，学习OpenGL的好东西-OpenGL Programming and Advanced Visualization System (Advanced Programming Part 1) the source-4 with books, learning the good stuff OpenGL (OpenGL high-level programming and visualization systems development (high-level programming chapter)-4 of the source with the book, learning OpenGL good things-OpenGL Programming and Advanced Visualization System (Advanced Programming Part 1) the source-4 with books, learning the good stuff OpenGL)

用于pivlab处理得到的流场数据画图，具体使用见注释(Flow field data plots for piv processing)

说明：  EM算法实现,是matlab主站上获得的可靠程序。(EM algorithm，which is from the matlab net about image processing.)

对可见光图片的人脸活体判断，内有C++和matlab实现，具体说明详见readme(For the visible light picture of the human face to determine, there are C++ and matlab implementation, specific instructions see readme)

图形验证码识别引擎 V1.1 可以识别数字(Graphics Recognition Engine Code V1.1)

利用matlab的DCT2函数，对图像做变换并压缩。并用8*8对图像分块，对每一块计算均方值作为阈值。(DCT2 use the matlab function, and transform the image so compressed. And 8* 8 image block, a calculation of each mean square value as a threshold.)
