该程序功能是实现对道路流动车辆统计。小模块功能有以下几个：1，对视频解帧并显示。2，对该视频训练背景图片。 3，利用背景图片用减背景法对测试视频进行前景提取，并进行阈值处理，图像分割，找出流动车的连通域。 4，对车辆进行统计。程序包内含有界面说明，以及程序使用的步骤和相关注意事项(The program function is to achieve movement of vehicles on the road statistics. A small module function has the following: 1 solution for video frames and displayed. 2, the video training background image. 3, using the background image used by the background method of testing the prospects for video extraction, and conduct threshold processing, image segmentation, to identify mobile car-connected domain. 4, vehicle statistics. Interface package contains instructions and procedures related to the use of the steps and considerations)

实现了一个小球自由落体碰撞地面并弹跳的过程，设置了一个碰撞衰减系数c,可以自己调整衰减速度。(The process of collision and bounce of a small sphere falling freely on the ground is realized. A collision attenuation coefficient C is set to adjust the attenuation speed by itself.)

可用于matlab 人脸检测，准确率较高。(It can be used in matlab face detection, with higher accuracy.)
