本文讨论了一种分布式蒙特卡罗（DMC）跟踪方法，实现了可穿戴式主动视觉系统的实时、准确的人脸跟踪。DMC是对客户机-服务器分布式体系结构的顺序蒙特卡罗方法的扩展。客户端以最小的延迟反馈跟踪结果用于可穿戴式有源摄像头的控制，服务器同时精确跟踪人脸。在我们的方法中，即使客户端无法与服务器通信，也可以完成跟踪过程，并且当客户端能够与服务器通信时，可以获得更准确的结果。我们已经在VizWear-Active系统上实现并演示了这种方法，该系统包括一个可穿戴的主动摄像头。
In this paper we discuss a distributed Monte Carlo (DMC) tracking method which achieves real-time and accurate face tracking for wearable active vision systems. The DMC is an extension of sequential Monte Carlo approaches to a client-server distributed architecture. The client feeds back the results of tracking for use in the control of the wearable active camera with minimal delay, and the server accurately tracks the faces at the same time. In our method, the client is able to complete the tracking processes even when it is unable to communicate with the server Furthermore, more accurate results are obtained when it is able to communicate with the server. We have implemented and demonstrated this method on the VizWear-Active system which includes a wearable active camera.
