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 tech-niques and detect the specified video event based on satisfiability checking on LTD_ALCO formulas.
