高斯混合模型的最大期望迭代求解算法,可用于图像区域灰度分布估计(Expectation maximazation(EM) for Gaussian mixture model(GMM) )

RGB 颜色选择器，可以自由选择颜色，也可以用吸管吸取屏幕颜色色值，便于程序员们开发(RGB color picker, you can choose colors freely, or you can suck the color value of the screen with a straw, which is easy for programmers to develop)

说明：  采用walsh进行处理，所得图片效果比较理想(Processed by walsh, results from the ideal image)

旋转图像回归，图像拍照时有角度，此程序是将图像置平。(Rotating image regression )

说明：  次文件夹包含两个程序，可以对振动信号进行包络分析，适合信号处理入门的朋友(do envelope analysis on vibration signal)

根据国外文献算法中所写的MATLAB代码，实现肤色检测与轮廓提取。(According to foreign literature written in MATLAB code algorithm to achieve skin color detection and contour extraction.)

全套的DCT域数字水印源代码matlab(A full set of digital watermarking of DCT-domain source code matlab)

能够将图像坐标转化为世界坐标，根据图像像素修改参数(Can transform image coordinates into world coordinates, and modify parameters according to image pixels.)

立体视觉代码。主要过程包括：harris角点检测，zncc最优策略匹配，扩散得到更多特征对应，计算disparity和对应颜色值。另外提供了两幅图片以及对应的特征匹配的结果和disparity图像。(Three-dimensional visual codes. The main process includes: harris corner detection, zncc optimal strategy for matching, the proliferation of more features of the corresponding calculation of disparity and the corresponding color value. Also provides a picture and two corresponding feature matching results and disparity images.)
