提出了一种大容量的可逆信息隐藏算法的详细实现方案。利用图像直方图中的多个零点或者最小点, 通 过修改图像像素的灰度值来隐藏信息, 并通过统计分析给出常用的信息隐藏的模型和算法。(Presents a large reversible capacity detailed information hiding algorithm implementations. Using the image histogram, or the minimum number of zero points, by modifying the image pixel gray value to hide the information, and is given by commonly used statistical analysis model and algorithm for information hiding.)

文件为图形的显示函数，如单个像素的显示，直线的显示，字符的显示(File for the graphic display function, such as a single-pixel display, a straight line display, character display)

模式识别的Sobel和Kirsch边缘检测程序(Sobel and Kirsch edge detection algorithm of Pattern recognition)

说明：  用matlab 实现的图像滤波，，，，，，，，，，(Image filtering realized by MATLAB,,,,,,,,,,)

压缩感知图像融合算法，效果很好滴，可以借鉴学习哦(Compressed sensing image fusion algorithm, the effect is very good drops, you can learn from, oh)

是一个颜色空间转换的MATLAB程序，一共有两个程序一个从RGB到YCRCB，一个是从YCRCB到RGB的程序。(Is a color space conversion of the MATLAB program, a total of two procedures from RGB to YCRCB, one is from YCrCb to RGB procedures.)

说明：  多阈值分割 ，基于otsu生成阈值，有用的可以试试(Multi threshold segmentation, threshold generation based on Otsu, useful can try)

常用数字图像处理，图像变换等功能的实现，锐化平滑等算法(digital image processing)

C# 仿QQ管家UI以及功能源码，效果不错，值得收藏

人脸识别源代码，分为人脸检测，人脸识别等几部分(Face recognition source code, is divided into face detection, face recognition and other parts)
