This invention describes a system for multimedia and cross-media search and retrieval of multimedia documents in a multimedia database. The invention processes a multimedia database into sets of features which it stores and indexes. Multimedia queries can then be made on the indexed multimedia database. The invention takes a multimedia query converts it into features which it matches against the ones in the index database. The process results in a list of documents sorted by their estimated relevance to the query . The recognition engines generate N-best lists for the objects in each multimedia document. These N-best lists are concise statistical representations of the multimedia data. These statistical representations enable the retrieval methods to be robust even when there are machine recognition errors, allowing retrieval of documents which would be missed by other retrieval systems.
