在MATLAB环境下进行对MPEG视频中图像的提取，对于视频技术爱好者有一定的参考价值(In the MATLAB environment with MPEG video on the extraction of image for video enthusiasts with some reference value)

The method works as follows. 1. For a data set with dimensionality, d, compute the variance of data in each dimension (column). 2. Find the column with maximum variance call it cvmax and sort it in any order. 3. Divide the data points of cvmax into K subsets, where K is the desired number of clusters. 4. Find the median of each subset. 5. Use the corresponding data points (vectors) for each median to initialize the cluster centers.
