基于概率主题模型的动作识别算法研究

A novel method of action recognition based on probabilistic topic model

在时空兴趣点以及3D-SIFT描述的基础上,采用概率主题模型进行动作识别,结果表明:概率主题模型不仅能够实现对视频中单个动作的识别,而且对复杂情况下的视频也有一定识别能力。

A novel method of action recognition based on probabilistic topic model is proposed to recognize several human common actions,on the basis of spatial-temporal interest point and 3D-SIFT description.The result shows that the probabilistic topic model has the recognition not only to single action in video,but also to the sequential video action under complex condition.
