运动目标识别与跟踪程序，具有相当不错的执行能力-There are many approaches for motion detection in a continuous video stream. All of them are based on comparing of the current video frame with one from the previous frames or with something that we ll call background. In this

使用帧差法，实现运动物体的检测.这是视频监控系统的一个基本要求,也是进一步进行目标分析的基础 。-a motion detection and background updating method was developed based on the coterminous frame differencing.
