The MPEG-7 visual description framework –concepts, accuracy, and applications

Abstract

This paper gives a brief introduction into the Visual part of the forthcoming new standard MPEG-7, the "Multimedia Content Description Interface". It then emphasizes on the aspects how the Visual Descriptors of MPEG-7 were optimized for efficiency, compactness and behavior similar to human visual characteristics. The MPEG-7 descriptors were mainly designed for signal identification and recognition in the context of multimedia applications; however, they are applicable wherever interoperability between distributed systems designed for the task of visual information recognition need a standardized interface. I this sense, MPEG-7 may become a key element in the process of convergence of multimedia related applications with computer vision systems.
