摘要 文章介绍了一个可以实时捕捉人体上半身运动的系统。该系统通过结合使用人脸检测、肤色检测和概率跟踪等技术,利用单个普通摄像头在一般的室内环境下跟踪人体的脸部和手臂关节位置。作为一个实时跟踪系统,该系统实现了跟踪的自动初始化以及自动从跟踪错误中恢复,并且在一定程度上处理光照变化、身体自遮挡等问题。该系统可以用于“虚拟现实”、“视频会议”、“基于摄像头的游戏”等一些领域中。 A real-time upper-body tracking system is introduced.In this system,several techniques,including facedetection,skin color segmentation,and probabilistic tracking probability tracking,are used to track a person's upper body's motion in usual indoor environments.This system can initialize the tracking and recover from failure automatically,and is robust to illumination change and body self-occlusion.This system can be applied to several fields such as "virtual reality", "video conference" , and "web-cam games".
