Monitoring dynamically changing environments by ubiquitous vision system

Accurate and efficient monitoring of dynamically changing environments is one of the most important requirements for visual surveillance systems. This paper describes development of a ubiquitous vision system for this monitoring purpose. The system consisting of multiple omni-directional vision sensors is developed to address two specific surveillance tasks: (1) Robust and accurate tracking and profiling of human activities, (2) Dynamic synthesis of virtual views for observing the environment from arbitrary vantage points.
