VIOLONE: Video Retrieval by Motion Example

Recent progress in hardware and operating system technologies has made it possible to manage multimedia data consisting of text, static images, sound and/or video. Video data is considered to be the most informative of these types of data. It presents a scene consisting of objects and the motion of objects conveying particular meaning of the scene. Thus, the inherent feature of video data lies in the motion of objects. In this paper, we present a system that retrieves video data by means of the motion of objects observed in the video data in the database. The system accepts a query for a video database, which is specified by drawing an example trajectory of an object, and retrieves video data by extracting a moving object observed in the video data. The proposed way of specifying a query condition is superior to other ways of representing a condition, e.g. by text, in the sense that it is suitable for representing the difference of motion.
