采用opencv 高斯处理视频并跟踪运动做前景背景分割(Gauss processes video and tracks motion to do foreground and background segmentation.)

帧间差分法分割目标物，分割效果良好，内附测试视频，已经调试成功，可以使用。(The inter frame difference method is used to segment objects, and the segmentation results are good. The test video is attached, which has been successfully debugged and can be used.)

一个完整的车牌识别系统闭应包括车辆检测、图像采集、图像预处理、车牌定位、字符分割、字符识别等单元。当车辆到达触发图像采集单元时，系统采集当前的视频图像。车辆识别单元对图像进行处理，定位出牌照位置，再将车牌中的字符分割出来进行识别，然后组成车牌号码输出。(A complete license plate recognition system should include vehicle detection, image acquisition, image preprocessing, licen
