Automatic video summarization for wireless and mobile environments

In this paper, we propose a novel video summarization technique using which we can automatically generate high quality video summaries suitable for wireless and mobile environments. The significant contribution of this paper lies in the proposed clustering scheme. We use Delaunay diagrams to cluster multidimensional point data corresponding to the frame contents of the video. In contrast to the existing clustering techniques used for summarization, our clustering algorithm is fully automatic and well suited for batch processing. We illustrate the quality of our clustering and summarization scheme in an experiment using several video clips.
