实现AVI视频的读取和背景检测，实现运动物体的实时跟踪,get frame from avi

实现对视频一帧帧播放，并实现背景相减，帧间相差法等，并实现运动目标的跟踪。-To achieve a frame of video playback, and to achieve background subtraction, inter-frame difference method, etc., and tracking moving objects.

进行多运动物体跟踪，可以识别多个物体并进行跟踪-Multi-moving objects tracking, multiple objects can be identified and tracked

视频中运动物体的跟踪，可用vs2010+opencv1.0运行。（注意opencv在vs中的配置，注意配清楚，才可正常运行代码）-Tracking moving objects in video, available vs2010+ opencv1.0 run. (Note that in vs opencv configuration, with attention to clear, before running the code)
