Multimedia Surveillance and Monitoring
Most surveillance and monitoring systems nowadays utilize multiple types of sensors. However, due to the asynchrony among and diversity of sensors, information assimilation how to combine the information obtained from asynchronous and multifarious sources is an important and challenging research problem. In this paper, we propose a hierarchical probabilistic method for information assimilation in order to detect events of interest in a surveillance and monitoring environment. The proposed method adopts a bottom-up approach and performs assimilation of information at three different levels - media-stream level, atomic-event level and compound-event level. To detect an event, our method uses not only the current media streams but it also utilizes their two important properties - first, accumulated past history of whether they have been providing the concurring or contradictory evidences, and - second, the system designer’s confidence in them. A compound event, which comprises of tw...
