一些源程序和一些电子课件，还有数字信号处理试验，很不错~！(Some source code and a number of electronic courseware, as well as digital signal processing test, very good ~!)

经典的em算法即期望最大化算法，可用于高斯混合GMM模型和聚类算法，(Classic em algorithm that expectation maximization algorithm can be used for Gaussian mixture models and GMM clustering algorithm,)

emd工具箱，用经验模态分解时一定要安装的工具箱，解压后添加进toolbox里，setpath后，记得更新工具箱，就可以使用了，我是用来分解信号进行信号处理的(emd toolbox with a time of empirical mode decomposition must install kit, unpacked add toolbox, the post setpath, remember to update the toolbox, you can use, and I was used to decompose the signal for signal processing)

he files in this package comprise the Matlab implementation of a foreground segmentation algorithm based upon graph cuts, described in: Better Foreground Segmentation Through Graph Cuts, N. Howe & A. Deschamps. Tech report, http://arxiv.org/abs/cs.CV/0401017. The file extractForeground.m contains a sample function that will perform a complete foreground segmentation for static camera video. It uses a number of parameters, which are described in the documentation. An attempt was made to choose sensible default values, but they may need to be adjusted for some videos. More generally, the implementation in extractForeground.m is only a suggestion of how the graph-based segmentation might be used. The same approach can be applied with other (perhaps time-adaptive) background models. The key step is at line 113 of the code, once the deviation array has been created. The graph-cut segmentation can be applied similarly to a deviation matrix computed in any other way.
