Video high-level semantic recognizing

Abstract

This paper presents an event semantic recognizing method based on Markov chain by stages, which takes object semantic as the bridge and is valid for recognizing complex event semantic. Semantic concept mapping mechanism based on semantic template is used to realize the automatic recognition of video semantic. In the experiment contrasting with IMAT system, our method shows more extensive recognition range and higher accuracy. Experimental results are encouraging, and indicate that the performance of the proposed approach is effective.
