Spatial media fusion project

Abstract

Most information includes some kinds of spatial data such as the address of a restaurant and the position of a person carrying a portable phone. The spatial data are useful as meta data of multimedia data because they provide spatial connections between multimedia data. The spatial data are called spatial keys because they join different contents with spatial relationships. The spatial media fusion project started last year (2000) to construct a framework of multimedia content circulation based on spatial keys. A geographic coordinate (x,y) is one kind of spatial data, but there are other kinds of spatial data, called spatial referenced data, which can be converted to geographic coordinates. We particularly focus on Japanese addresses and camera parameters as spatial referenced data. Using two kinds of spatial referenced data, we integrated text data and photo/video data in the form of spatial keys.
