Intelligent surveillance uses computer algorithms to interpret what a camera records. The system can be programmed to look for particular things, like an unattended bag or people walking somewhere they don't belong.
"If you think of the camera as your eye, we are using computer programs as your brain," said Patty Gillespie, branch chief for image processing at the Army Research Laboratory in Adelphi, Maryland. Today, the military funds much of the smart-surveillance research.
At the University of Maryland, engineering professor Rama Chellappa and a team of graduate students have worked on systems that can identify a person's unique gait or analyze the way someone walks to determine if they are a threat.
A camera trained to look for people on a watch list, for example, could combine their unique walk with facial-recognition tools to make an identification. A person carrying a heavy load under a jacket would walk differently than someone unencumbered which could help identify a person hiding a weapon. The system could even estimate someone's height.
