Content-based pre-indexed video
Nuno M. Vasconcelos, Andrew Lippman · 2002
The viability of large distributed image databases is strongly dependent on the development of new image representations capable of providing support for extended functionality, directly in the compressed domain. We have previously introduced one such representation (library-based coding) which we now augment with statistical pre-indexing schemes, automatically built at the time of encoding, that provides several layers of content description allowing efficient content-based retrieval and summarization.
