Video quality assessment methodology development quality monitoring in multimedia systems

Multimedia stream flows through several networks and subsystems, which can impair degradations due to various processing and transmission conditions, before reaching the end-user. Video quality assessment and control within the multimedia systems is in this context a highly important issue and is considered as a necessity for reliable and high Quality of Service multimedia networks in broadcast, mobile and IPTV applications. The main goal of the proposed project is a real-time system development for content-based and subjective-driven visual quality assessment, which would facilitate design and management of an advanced multimedia systems and networks with reliable and controllable video quality. Concerning the algorithm development the aim is to first develop objective measures for particular video artifacts and video content and to subsequently integrate them in a sophisticated manner into the overall quality model which would be subject-driven and optimized for particular video content. Another important aspect of the project is a real-time implementation of the developed video quality model on standard multi-core platforms with pre-validation on a demonstrator. Finally, the integration of such monitoring system into the multimedia networks is targeted, for which the final validation is planned to be done with potential users (e.g., telecom operators). The outputs of the project will include: quality assessment methodology, real-time system implementation and integration.
