Multimedia information becomes available from many sources around the world exponentially; many people would like to use this information for various purposes, making the multi media databases to be accessed by many users. This challenging situation led to the need for a solution that quickly and efficiently searches for and/or filters various types of multimedia information of user interest. MPEG-7 is a multimedia content description standard that describes multimedia contents so users can search, browse, and retrieve the contents more efficiently and effectively than they could using today¡¯s leading text-based search engines. The significance of spatial relationships has been pointed out by a number of researchers in spatial and image databases. Spatial relationship representations used by GIS (Geographic Information System) community are not enough to express image contents because they lack the expressive power. Therefore we propose the new improved spatial relationships that are suitable for expressing contents of images. In order to retrieve the desired multimedia contents, we have to search the appropriate Description Schemes (DSs) that describes structure and semantics of the multimedia data. MPEG-7 does not describe any indexing mechanism of those DSs. We may need some indexing mechanism in order to make it fast and efficient retrieval.
