dc.description.abstract | During the last years, the amount of multimedia content has greatly increased. This has multiplied the need of efficient compression of the content but also the ability to search, retrieve, browse, or filter it. Generally, video compression and indexing have been investigated separately. However, as the amount of multimedia content grows, it will be very interesting to study representations that, at the same time, provide good compression and indexing functionalities. Moreover, even if the indexing metadata is created for functionalities such as search, retrieval, browsing, etc., it can also be employed to increase the efficiency of current video codecs. Here, we use it to improve the long term prediction step of the H.264/AVC video codec. This paper focuses on the comparison between four different MPEG-7 descriptors when used in the proposed scheme. |
