摘要
识别视频中的人的动作是视频语义分析方向的一个关键研究课题,在很多领域有广阔的应用前景,如人机交互,智能监控,基于内容的视频数据检索等。本文从问题的定义,一般解决思路,到两大关键问题——动作表示和动作识别的解决方法进行了详细论述,并指出了现有方法存在的问题以及发展方向,为该领域的初学者提供有价值的参考。
Human action recognition is a key topic in the field of video semantic analysis. There are wide prospects of applications in many fields, such as human-computer interfaces,video surveillance, content -based video indexing and so on. In this paper, the state-of-the-art work on this topic about the definition of the problem, the typical process flow of the system and the existing methods to action representation and recognition were reviewed. Then the limitation of the approaches that are reported in literature and the potential direction in the future are pointed out,which should have some reference value to the beginners on this topic.
