Abstract
- Video summarization is an economical way of representing video contents and is useful for effective and quick browsing of the relevant activity present in the video. Most current video summarization approaches do not provide the correct insight of the events occurring in the video, such as moving the objects in a nonchronological order and tampering with the background and size of the objects. In this paper, we present an approach to create a video summarization that is a precise representation of the video content. First, our approach finds out the salient activities that are taking place in the video using an optimization framework for static and dynamic scenes. Second, the frames with the salient activities are stitched using alpha matting to form a single frame. Third, the summarized frame over multiple video shots obtained by our approach gives superior retrieval performance with image queries while reducing retrieval latency and memory requirement. This paper proposes a single frame-based indexing of the video database instead of multi-frame indexing as it is an interesting and potentially promising approach. Finally, several experiments are carried out to evaluate the proposed approach. The experiments demonstrate that the video summarization produced by our approach gives a realistic view of the events in the video, while the reduction in computational complexity and memory requirement is high.
