基于背景差分法和帧间差分法的目标跟踪 应用了二维滤波，效果较好-Based on background difference and frame difference method applied to two-dimensional target tracking filter, better

通过多摄像头实现物体的跟踪，通过一个摄像头进行背景差分的人物识别，然后另外的一个摄像头进行投影。-Through a multi-camera tracking objects through a camera the background differential character recognition, and then a camera projection.

基于MATLAB下的背景差分算法，通过第一帧和中间帧以及最后帧得出背景。-Based on the background subtraction algorithm under the matlab programming language, through the first frame and the middle frame and the last frame background.
