Surveillance video analytics for large camera networks
Peter Tu · SPIE Newsroom · 2007
Intelligent video research focuses on automatic camera calibration and person detection, tracking, and reacquisition. Extensive networks of surveillance cameras are increasingly deployed in public and private facilities, with tremendous potential value for safety and security. However, because manual monitoring of large numbers of video sources is not feasible, surveillance imagery is often simply directed to massstorage devices, to be used only forensically and for data mining. On-line computer-based video analysis represents an alternative to this traditional approach. This new paradigm continually apprises security personnel of who is on site, where they are, and what they are doing. It offers the prospect of increased productivity and highly advanced sitewide security. Our approach to video analytics for security starts by establishing
