In this paper, we describe our approach to the TRECVID 2007 BBC Rushes Summarization task. Our processing is composed of several steps. First the video is segmented into shots. Then, one-second video segments are clustered into similarity classes. The most important non-redundant shots are selected such that they maximize the coverage of those similarity classes. Then shots are dynamically accelerated according to their motion activity to maximize the content per time unit. Finally they are optimally grouped by sets of four to be presented using split-screen display. The summaries produced have been evaluated in the TRECVID campaign. We present a first attempt at automating the evaluation process.
