W4S:A Real-Time System for Detecting and Tracking People in 2-1/2 D
Computer Vision — ECCV'98, (1998)
Abstract
W4S is a real time visual surveillance system for detecting and tracking people and monitoring their activities in an outdoor environment by integrating realtime stereo computation into an intensity-based detection and tracking system. Unlike many systems for tracking people, W4S makes no use of color cues. Instead, W4S employs a combination of stereo, shape analysis and tracking to locate people and their parts (head, hands, feet, torso) and create models of people's appearance so that they can be tracked through interactions such as occlusions. W4S is capable of simultaneously tracking multiple people even with occlusion. It runs at 5-20 Hz for 320x120 resolution images on a dual-pentium 200 PC.
