Description
Summary:With recent development of digital broadcasting and networks, the volume of image data to be handled has rapidly increased. To handle massive amounts of image data on a network, the authors have proposed “advanced database TV” (ADTV) in which image data on the network can be shared. This paper proposes a real‐world video system which is a realization of ADTV, with examples. In this paper, a method of a self‐organized data structure based on image objects is proposed, since the structural elements of images (e.g., scenes, cuts, and objects) are essential elements. The method can be realized by matching a real‐world video of a city and its map. It is shown that a significant improvement of the matching accuracy can be achieved by obtaining three‐dimensional information from the images. © 2002 Wiley Periodicals, Inc.
