LBG算法，初始码本随机给出，然后根据对训练矢量的划分，计算形心，更新码本。原代码中含有去空胞腔的程序。-LBG algorithm, given a random initial codebook, and then based on the division of the training vector, computing the centroid, update this code. Contains the original code to empty cell process.

这是好的LBG程序，对初学的人有相当大的帮助，一看就会懂很多。-this is good LBG programme, it is useful for you.
