Abstract

Motion information in a video clip plays an important role in characterizing the content of the clip. In this paper, we propose the shape variation descriptor to describe and retrieve video clips based on the shape variation caused by object movement along time. Similar to accumulator cells, a shape variation map was first constructed by cumulating binary shape images in the sequence of the video clip. A shape descriptor called ART, obtained from the map, then becomes a feature set for the shape variation of the clip. Experimental results over hundreds of video and animation clips show that our approach of retrieving video clips based on shape variation compares favorably against an alternative edge based method.
