Abstract
The video information retrieval system includes a client for inputting video data or retrieving a registered video file, and a retrieval server for registering video data transmitted from the client and retrieving the registered video data in response to a request from the client. The retrieval server analyzes a video stream upon registration of the video data and separates contents of a video constituting the video stream. The server extracts annotation information such as image feature vectors for each of the separated video contents and stores the annotation information in a video information table as a video object. The retrieval server performs retrieval processing in a unit of object on the basis of the retrieval condition designated for each video object by the user and judges the simultaneous appearance on the basis of appearance time section information of the object coincident with the retrieval condition to thereby extract the user's desired video scene and present it to the user.
