Hierachically Categorized Performance Evaluation Criteria for Intelligent Surveillance System

초록

In urban transit station, the use of analog CCTV surveillance system has increased to detect and prevent crimes, terrors, suicides, fires and so on. But these systems have a problem that a manager has to monitor consistently the scene in transit station, so they cannot cope with crimes, terrors, and fires in real-time. There is a trend in video surveillance towards using the intelligent surveillance system, which is expected to provide efficient assistance to solve this problem. This system automatically analyzes image sequences acquired from various cameras and aware of context, so they can cope with crimes and terrors in real-time. It is therefore very important to develop this system and necessary to establish performance evaluation criteria to evaluate the system and improve the performance of the system. Many evaluation criteria have been presented in previous research but they are not classified properly according to the purpose of evaluation. We categorize these criteria hierarchically to help making a decision of proper metrics according to specific application domain, s.t. intelligent surveillance system in urban transit station.
