Dynamically Emerging Semantics in an MPEG-7 Image Database

We examine the efficacy of using MPEG-7 in a native XML database environment for managing aerial image data. This application domain exhibits unique challenges in the management of image data which is continually changing, requiring continuous update of the schemas and methods for mining various geographic region properties. We show how MPEG-7 descriptors can be associated with aerial images and their derived features at each stage of the image insertion process, producing a multifaceted integrated representation, which can be used to give the database administrator an indication as to when this representation should be rebuilt, so as to result in improved retrieval behavior. In the absence of specialized indexes for inexact descriptor matching, we also show how MPEG-7 descriptors can be used to speed up this process.
