混合高斯分布EM算法，可以算混合高斯分布的三个参数。混合高斯分布更接近系数分布。(mixed Gaussian distribution EM algorithm can calculate mixed Gaussian distribution of the three parameters. Mixed closer to the Gaussian distribution coefficient.)

对比CPU和GPU加速，pcl::cuda的使用教程，利用随机采样一致(RANSAC)去除地平面等例子。(Compare CPU and GPU acceleration, pcl::cuda tutorial, using random sampling consistency (RANSAC) to remove ground plane and other examples.)

This DataEntryFilter filters data entries based on whether their names match a given StringMatcher.

meanshift图像分割 1.mean shift 的迭代过程只做了一次（为了简单） 2.对图像中的某一点进行平移时，只考虑了距离它小于2*hr的点，而不是图像中所有的 点。 3.实验过程中只用到了gauss核，虽然提供了method的选择，但在进行值域加权时只用 到gauss核，如果需要请自己改正。(meanshift segmentation)

基于相位和Lucas Kanade方法的光流计算matlab源程序。(Based on the phase and Lucas Kanade optical flow calculation methods matlab source.)

实现了三种图像匹配算法 1：归一化互相关匹配算法 2：基于Hausdorff距离的图像匹配算法 3：图像不变矩匹配算法(Implements three image matching algorithm 1: normalized cross correlation matching algorithm 2: image matching algorithm based on Hausdorff distance 3: The image matching algorithm invariant moments)

关于脆弱性水印的，是一个挺不错的。希望能帮助到有需要的同学(on vulnerability watermark is a quite good. Intend to help the needy students)

一种基于关键点的复制粘贴检测算法，可以完成两幅图像的关键点匹配，也可以检测到一副图像是否经过复制粘贴后放大缩小、旋转等篡改操作(Key matching a replicon paste detection algorithm based on key points, you can complete two images, it can also detect whether an image after copying and pasting zoom, rotate, etc. tampering operation)

实现一个信号的WVD变换，针对的信号是非平稳的随机信号(To achieve a WVD transformation of a signal, the signal is a non-stationary random signal.)

图像分割源码，是一种基于图论的方法做的。分割的质量超好，不信的话下载下来看，你就清楚了！(Image segmentation source code, is a method based on graph theory to do. Segmentation quality is super good, do not believe it download the next run, you will be clear!)
