Pfinder是一种用于对人进行跟踪和解读的实时系统。它在一台标准的SGI Indy计算机上运行，并且在许多不同的物理位置对数千人进行了可靠的操作。该系统使用颜色和形状的多类别统计模型，以便在各种观察条件下获得头部和手部的二维表示。这些表示对于诸如无线接口、视频数据库和低带宽编码等应用是有用的，且无需繁琐的电线或附加的传感器。
Pfinder is a real-time system for tracking and interpretation of people. It runs on a standard SGI Indy computer, and has performed reliably on thousands of people in many different physical locations. The system uses a multi-class statistical model of color and shape to obtain a 2-D representation of head and hands in a wide range of viewing conditions. These representations are useful for applications such as wireless interfaces, video databases, and low-bandwidth coding, without cumbersome wires or attached sensors.
