说明：  图像四叉树分解，对于图像灰度值进行四叉树分解，并覆盖原图显示(Image quadtree decomposition)

说明：  opencv入门程序，使用opencv模式读取图像并显示，在vs环境下调用matlab进行图像读取和显示(opencv entry procedures, read the image using opencv mode and display, in the vs environment, call matlab to read and display the image)

数字隐写，将txt文档藏进图片中，并能够从图片中解出隐藏的文本。(Digital steganography )

使用 RANSAC 算法计算仿射变换矩阵(RANSAC algorithm using an affine transformation matrix)

累加颜色直方图法图像检索,包含基本程序、图片库以及WORD说明文档(Cumulative color histogram image retrieval, including basic procedures, photo gallery and documentation WORD)

说明：  基于opencv平台编写的单目相机标定程序，使用的张正友的方法，只要准备十二张单目相机拍摄的棋盘格的图片就可以标定出单目相机的焦距等参数，建立单目相机坐标系。可以用于机器视觉测量中，也可以用于双面相机标定的前一步，精度很高。(Based on the monocular camera calibration program compiled by the OpenCV platform, the method of Zhang Zhengyou is used to calibrate the focal length and other parameters of the monocular camera and establish a monocular camera coordinate system as long as 12 pieces of chessboard pictures taken by the monocular camera are prepared. It can be used in machine vision measurement, and it can also be used in the previous step of the calibration of the double-sided camera, with high precision.)

应用于图像压缩的SPIHT算法代码，此代码的步骤很清晰，我自己加了很多注释，特别好理解。(SPIHT code which is used in image compression,with many notes of my own so really easy to understand.)

一些图像处理中的增强算法，一些些一些些一些些(Some of the enhanced image processing algorithms, some more some more)

基于matlab的ssim图像质量评价，验证还可以(Image quality evaluation)

david lowe 的matlab程序，用于图像特征点的匹配。(david lowe)
