Video surveillance systems have long been promoted as being effective in improving public safety. However, due to the increasing number of cameras being installed, the trend has been to record the surveillance videos (with only partial monitoring) and to use the videos mainly for a forensic, or reactive, response to crime and terrorism, often detected by other means. Recently the immense cost of successful terrorist attacks on soft targets such as mass transport systems has indicated that forensic analysis of video after the event is not an adequate response. What is needed is proactive security to help prevent future attacks.
Our main research goal is the development and improvement of advanced surveillance systems, which employ computer monitoring of all video feeds. This considerably assists in the detection of events of interest as they occur — examples include the detection of left luggage as well as real-time recognition of a suspected terrorist in a crowded railway station.
