Semantic Video Indexing.

Query-by-keyword is the paradigm on which machine-based text search is still based. Elaborating on the success of text-based search engines, query-by-keyword also gains momentum in multimedia retrieval. For multimedia archives it is hard to achieve access, however, when based on text alone. Multimodal indexing is essential for effective access to video archives. For the automatic detection of specific concepts, the state-of-the-art has produced sophisticated and specialized indexing methods. Other than their textual counterparts, generic methods for semantic indexing in multimedia are neither generally available, nor scalable in their computational needs, nor robust in their performance. As a consequence, semantic access to multimedia archives is still limited. Therefore, there is a case to be made for a new approach to semantic video indexing. [ABSTRACT FROM AUTHOR]
