Abstract
Pfinder is a real-time system for tracking people and interpreting
their behavior. It runs at 10 Hz 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 interfaces, video databases, and
low-bandwidth coding
