说明：   本文介绍一个实时视频对象计数系统的设计原理和实现方法[’]。这个系统目前已经应用十毛主席纪念堂，对每日瞻仰人数进行实时的统计，为纪念堂提供基本的统计数据。
( An image processing system was <levelope<1 to recognize au<l trace video objects to automatically count people. This paper describes the system design principles including the color model transparency, the physical models of the object motion, multi}>bject tracing, counting algorithms, au<l reasonable simplifications. The system detects au<l counts moving objects in a specific area. The counting system error is less than 3％. )
