Online action recognition using covariance of shape and motion.
Computer Vision and Image Understanding（2014）
摘要
•A descriptor for describing action in terms of shape and motion is proposed.•The descriptor is employed in the online action recognition scenario.•Two runtime optimizations are introduced to enable applicability in real time.•The method is simple, fast and accurate enough to be of practical value.
