Human-centric navigation system Video Vortex for video retrieval

This paper presents a human-centric navigation system “Video Vortex” for video retrieval. This system is realized by the following functions: (i) Collaborative use of multimedia data for their multi-modal analysis, (ii) Preference extraction for the system to adapt to users´ individual demands, and (iii) Adaptive visualization for users to be guided to their desired contents. These functions effectively provide a solution to the conventional problems of not being able to satisfy various users´ demands, and successful video retrieval becomes feasible.
