COSMOS-7: Video-Oriented MPEG-7 Scheme for Modelling and Filtering of Semantic Content

Harry Agius * and Marios C. Angelides §

Brunel University, School of Information Systems, Computing and Mathematics, St John's, Uxbridge, Middlesex UB8 3PH, UK

MPEG-7 prescribes a format for semantic content models for multimedia to ensure interoperability across a multitude of platforms and application domains. However, the standard leaves it open as to how the models should be used and how their content should be filtered. Filtering is a technique used to retrieve only content relevant to user requirements, thereby reducing the necessary content-sifting effort of the user. This paper proposes an MPEG-7 scheme that can be deployed for semantic content modelling and filtering of digital video. The proposed scheme, COSMOS-7, produces rich and multi-faceted semantic content models and supports a content-based filtering approach that only analyses content relating directly to the preferred content requirements of the user.
