Abstract

Disclosed is a multimedia database for use in distributed network environments. A query processing module transforms user queries into search transformations that can be used for indexing; an attentional selection module records salient information represented in images by a hierarchy of feature maps, saliency maps and combined saliency maps; a declarative memory comprises active modules that update the representations acquired over time for the same images, as well as across images, to cluster, categorize and organize information extracted from different images by the attentional selection module; and an indexing mechanism utilizes the search transformations from the query processing module to search the declarative memory for an answer to a user query. The multimedia database is used in distributed network environments wherein a server can select and coordinate information flow between multiple database sites and user sites, provide effective multimedia representation, create indexes on multimedia content of said database sites to derive a set of target multimedia database sites and, enable database queries descriptions and final search results to be conveyed to a user, records information needed for database selection, generates useful query patterns based on memorization of responses patterns from various databases based on user queries, and directs interactive dialogue between a user and multimedia databases.
