Comparison of MPEG-7 descriptors for long term selection of reference frames
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.Peer ReviewedPostprint (published version
