Tracking human motion in an indoor environment

This paper presents an approach to tracking human motion in a sequence of monocular images. The process consists of detecting motion, segmenting moving subjects by recovering the background and, finally, tracking the subject of interest. The usual assumptions of small image motion, a fixed viewing system and constant velocity are systematically relaxed. Two cases are studied: (1) a viewing system with negligible motion, and (2) a viewing system with non-negligible motion.
