COSMOS-7: A Video Content Modeling Framework for MPEG-7

Abstract

As the amount of available multimedia documents is increasing, it is becoming harder to access and manage such files according to what they represent. Since the well-known text-based search engines are not adequate for that task, content modeling is assisting by providing information not about the actual bits that constitute a media file, but about their meaning, in other words the bits about the bits. The COSMOS model successfully integrates low level and high-level semantics into a single framework, and is therefore a complete and operational scheme for describing content related information. The MPEG-7 scheme standardizes content modeling and since its introduction in 1999 has now reached a mature state. As applications to create MPEG-7 content are scarce, the COSMOS model can now not only be used to create multimedia content but also act as an application for creating MPEG-7 compliant output.

Automatic Feature Extraction to COSMOS-7 Content Models

“…Then, we unfold the content features indexing methods need in order to produce a rich and detailed MPEG-7 content model. Finally, we explain how COSMOS-7 [5] extracts such features from the AV material followed by a discussion on how it translates these into an MPEG-7 content model.…”
