An integrated approach to summarization and adaptation using H.264/MPEG-4 SVC / Luis Herranz in Signal processing. Image communication, Vol. 24 N° 6 (Juillet 2009)

Martínez, Auteur Article en page(s) : pp. 499-509 Note générale : Electronique Langues : Anglais (eng) Mots-clés : Video  summarization  Scalable  video  coding  MPEG-4  SVC  H.264/MPEG-4  AVC  Video  adaptation Index. décimale : 621.382 Dispositifs électroniques utilisant les effets des corps solides. Dispositifs semi-conducteurs Résumé : The huge amount of multimedia content and the variety of terminals and networks make video summarization and video adaptation two key technologies to provide effective access and browsing. With scalable video coding, the adaptation of video to heterogeneous terminals and networks can be efficiently achieved using together a layered coding hierarchy and bitstream extraction. On the other hand, many video summarization techniques can be seen as a special case of structural adaptation. This paper describes how some of them can be modified and included in the adaptation framework of the scalable extension of H.264/AVC. The advantage of this approach is that summarization and adaptation are integrated into the same efficient framework. The utility of this approach is demonstrated with experimental results for the generation of storyboards and video skims, showing that the proposed framework can generate the adapted bitstream of the summary faster than a conventional transcoding approach.

On the use of hierarchical prediction structures for efficient summary generation of H.264/AVC bitstreams / Luis Herranz in Signal processing. Image communication, Vol. 24 N° 8 (Septembre 2009)

Dispositifs semi-conducteurs Résumé : Video summarization refers to an important set of abstraction techniques aimed to provide a compact representation of the video essential to effectively browse and retrieve video content from multimedia repositories. Most of these video summarization techniques, such as image storyboards, video skims and fast previews, are based on selecting some frames or segments. H.264/AVC has become a widely accepted coding standard and is expected that many of the content will be available in this format soon. This paper proposes a generic model of video summarization especially suitable for generating summaries of H.264/AVC bitstreams in a highly efficient manner, using the concept of temporal scalability via hierarchical prediction structures. Along with the model, specific examples of summarization techniques are given to prove the utility of the model.
