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

VC6.0+opencv环境下运动检测的实例，使用了帧差法、GMM方法等，可以对比不同建模方法的效果-VC6.0+ opencv environment, motion detection example, using the frame difference method, GMM methods, you can compare the effect of different modeling methods

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.
