Pfinder是一种实时系统，用于跟踪人们和解释其行为。它在标准SGI Indy计算机上的10Hz运行，并且在许多不同物理位置的成千上万的人都可以可靠地执行。该系统使用颜色和形状的多类统计模型在广泛的观看条件下获得头和手的2D表示。 Pfinder已成功地用于广泛的应用程序，包括无线界面，视频数据库和低带宽编码。
Pfinder is a real-time system for tracking people and interpreting their behavior. It runs at 10Hz on a standard SGI Indy computer, and has performed reliably on thousands of people in many different physical locations. The system uses a multiclass statistical model of color and shape to obtain a 2D representation of head and hands in a wide range of viewing conditions. Pfinder has been successfully used in a wide range of applications including wireless interlaces, video databases, and low-bandwidth coding.
