说明：  目前运动目标检测与跟踪的各种算法，对算法进行分析比较，提出了改进后运动检测和运动跟踪算法，在VC++6.0平台采用OpenCV视觉库开发，实现了视频运动目标检测与跟踪系统。
(At present, the algorithms of moving target detection and tracking are analyzed and compared, and the improved motion detection and tracking algorithm are proposed. The OpenCV vision library is developed on the VC++6.0 platform, and the video moving target detection and tracking system is realized.)
