Temporal segmentation of videos: a new approach
Mourad Cherfaoui, Christian Bertin · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1995
Several works have been carried out to achieve automatic video segmentation into meaningful parts. Video shots usually correspond to these meaningful parts. Many techniques have already been proposed1'2'3'4'5. Currently, finer segmentation ofvideos based on camera movements is sought. Figure 1 shows a video segmented as usual and in a finer way. Cameraoperation based segmentation allows us to better describe video contents for video-database applications5. It also allows to achieve semantic coding for very low bitrate video compression. In this paper, we propose a method that achieves automatic video segmentation based on camera movements. In section 2, we define a camera operations model. Using this model, we present in section 3 our video segmentation method. Experimental results are presented in section 4. Finally, we make a quick comparison of our method with the one presented in 6.
