Video Snapshot: A Bird View of Video Sequence

Video is an information-intensive media with much redundancy. Therefore, it is desirable to be able to quickly browse video content or deliver videos in limited bandwidth, which can be achieved by effective video summarization. In this paper, we present a novel pictorial video summary, called Video Snapshot, which is a bird view of video enabling viewers to grasp main contents of video at a glance. Moreover, a comprehensive scoring scheme for content filtering called PRID (Pleasurable, Representative, Informative and Distinctive), and an optimized video visualization algorithm are also proposed. The encouraging results indicate that many potential digital video applications may be leveraged by Video Snapshot, such as video browsing, retrieval and delivery in heterogeneous computing and networking environments.
