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.DEWEY : 361.382 ISSN : 0923-5965 En ligne : http://www.sciencedirect.com/science?_ob=PublicationURL&_tockey=%23TOC%235640%23 [...]
