光流法之一：codebook BGS代码，参考论文Real-time foreground–background segmentation using codebook model （Kyungnam Kima,, Thanarat H. Chalidabhongseb, David Harwooda, Larry Davis），进行了简化。

实验效果：似乎噪声点太多了。-One of the optical flow method: the BGS codebook code, reference papers Real-time foreground-background a segmentation a using codebook the model (Kyungnam Kima, Thanarat of H. Chalidabhongseb David Harwooda, Larry Davis), carried out to simplify.

Experimental results: it seems that the noise point too much.
