A dynamic description logic based system for video event detection

Abstract

Video event detection is an important research area nowadays. Modeling the video event is a key problem in video event detection. In this paper, we combine dynamic description logic with linear time temporal logic to build a logic system for video event detection. The proposed logic system is named as LTD ALCO which can represent and inference the static, dynamic and temporal knowledge in one uniform logic system. Based on the LTD ALCO, a framework for video event detection is proposed. The video event detection framework can automatically obtain the logic description of video content with the help of ontology-based computer vision techniques and detect the specified video event based on satisfiability checking on LTD ALCO formulas.
