最基本的背景差分（background subtract）方法：frame difference。-the basic background subtract method: frame difference.

用MATLAB进行图像处理。meanshift的方法进行图像的差分，以消除背景变化的问题-Image processing using MATLAB. meanshift the differential image, to eliminate the problem of the background changes

用C++进行图像处理。meanshift的方法进行图像的差分，以消除背景变化的问题-Image using C++. meanshift the differential image, to eliminate the problem of the background changes
