矫正桶形畸变，只是用了坐标变化，目前在研究张正友的算法，日后会上传的(correct the distortion of picture)

著名的LUCAS KANADE算法，用于图像匹配，跟踪，识别(LUCAS KANADE well-known algorithm for image matching, tracking, identification)

图论分割算法之一“Nystrom Ncut”MatLAB源程序。(MatLAB codeof “Nystrom Ncut”.)

Image Mosaicing interesting application in computer vision

Canny进行边缘检测，得到图像的边缘，然后sobel算子对图像边缘进行卷积，然后用Hough变换进行直线提取。(Canny edge detection to obtain the edge image, and then sobel edge operator for convolution, and then use the Hough transform for straight line extraction.)

使用边缘跟踪，种子填充等算法提取图像边界，然后使用并行的方法来计算图像的距离图。(using edge tracking and seed filling algorithm to detect the edges of images, then use the parallel approach to the calculation of the distance between the image map.)

说明：  人脸认证流程，计算人脸认证算法的FAR,FRR(Face verification process, the face authentication algorithm calculated the FAR, FRR)

基于SUFT的特征提取与匹配，内涵详细的文档说明，很好的实现了特征提取与匹配，该方法较基本的SIFT有很大的提高(Extraction and matching of features based on SUFT, detailed content of the documentation, very good realization of the feature extraction and matching, SIFT the method is basic is greatly improved)

em算法求解混合高斯模型，适合图像处理中，对象分割(em algorithm Gaussian mixture model suitable for image processing, object segmentation)

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.)
