A Method for Animation Video Abstract

In recent years, animation is increasingly rapid developing, and the processing and abstract of animation video have become a hotspot. Animation video abstract is an important step in the research of animation video.Based on distinct property of animation video which is different from that of other videos, especially news video and sports video, a video abstract method, suitable for animation video, is proposed. In this paper, the construction of animation video is analyzed. Then the visual character and clear construction are gotten. The granularity of video scene is defined. Based on content evaluation model of scene significance and The granularity of scene, we find the important scenes of the video. Then, in the temporal order, the video abstract including stroyboard and video skim is proposed. Experimental results indicate that the proposed method extracts animation video abstract efficiently. The two forms of video abstracts are produced by this method can generalize and condense the animation video effectively.
