本文提出了一种系统，能够跟踪多个人脸在不同的姿态（倾斜和旋转）可靠的实时。该系统由两个交互式模块组成。第一模块执行受旋转影响的面部的检测。第二种是基于在线学习的人脸跟踪。在系统中嵌入了两个模块之间的切换机制，以自动决定可靠跟踪的最佳策略。当检测和跟踪模块中的一个模块没有给出结果或给出不可靠的结果时，该机制能够实现检测和跟踪模块之间的平滑过渡。实验结果表明，该系统能够在复杂背景下对多个人脸进行可靠的实时跟踪，包括离面旋转、最大倾斜90度、快速非线性运动、部分遮挡、大尺度变化以及摄像机运动等
This paper presents a system that is able to track multiple faces under varying pose (tilted and rotated) reliably in real-time. The system consists of two interactive modules. The first module performs detection of face subject to rotations. The second does online learning based face tracking. A mechanism of switching between the two modules is embedded into the system to automatically decide the best strategy for reliable tracking. The mechanism enables smooth transit between the detection and tracking module when one of them gives no results or unreliable results. Results demonstrate that the system can make reliable real-time tracking of multiple faces in complex background under out-of-plane rotation, up to 90 degree tilting, fast nonlinear motion, partial occlusion, large scale changes, and camera motion
