Key frame extraction using inter-shot information

Key frame extraction is one of the basic procedures relating to video retrieval and summary. Efficient key frame extraction techniques will facilitate video browsing systems, which have wide applications in the real world. We establish a new criterion for well-representative key frames and correspondingly, create a key frame selection algorithm based on FF-ISF. Its novelty lies in that it not only uses intra-shot information but inter-shot information as well, for key frame extraction.
