采用了Harrtraining和离子滤波算法实现了拥挤人群人头计数，非常有用。VC++和Opencv开发，采用Oepncv中的Harrtraining训练一个分类器即可运行-Human detection and tracking in high density crowds is an unsolved problem. Standard preprocessing techniques such as background modeling fail when most of the

在opencv环境下开发的监视器画面上人体运动跟踪-Human motion tracking opencv environment developed under the monitor screen

opencv 实现人体运动跟踪，精度中等，有一定的参考价值。-opencv schieve human motion tracking, accuracy is only moderate, there is some reference value.
