在整个实现过程中，背景建模是核心，采用基于高斯混合模型的背景建摸方法。-Throughout the implementation process, background modeling is the core, built on the background of GMM touch method.

运用高斯混合模型，识别车辆，分割车辆，检测车流量，运算很快，效果不错-Using the gaussian mixture model, identification of vehicles, vehicle segmentation, detection and traffic operation soon, effect is good
