Abstract: A method of preprocessing a plurality of raw video files has the steps of a user selecting the plurality of raw video files, creating an exposure histogram for raw video files on a predetermined interval, creating a color histogram for at least one of the plurality of raw video files on a predetermined interval, determining a camera movement velocity, determining a camera trajectory, determining an image sharpness for at least one of the plurality of raw video files on a predetermined interval, and determining a raw video location based GPS information embedded into the plurality of raw video files. In an embodiment, determining a scene location comprises the steps of indexing the color histogram, indexing the raw video location based on geographic proximity, grouping the scene location based the color histogram, grouping the scene location based on the raw video location and determining a plurality of scene groupings.

Abstract: An electronic agent for a user including a server member for providing information concerning the user, the server member including an FTP server to provide information, a web server to provide access to information of the user and an Internet semantic server for indexing new information and providing responses to queries of clients. The electronic agent also includes a categorizer for creating hierarchic semantic space and crawler members for performing directed information searches. The crawler members arrange results of the directed information searches and deliver the arranged results of the directed information searches to users. A network system for exchanging information that includes providing a plurality of neurocomputers as agents associated with users, linking the plurality of agents, accumulating knowledge by each agent according to preferences by the user associated with the agent, and exchanging monetary value between the plurality of agents for answering queries and referring queries.
