MOSAIC: MOdels and Simulation techniques for discovering diAbetes Influence faCtors

Research Areas

The main objective of the MOSAIC project is to develop and prove reliable methods for the assessment of picture quality and degradation. It will also investigate operational system features which influence subjective image quality such as: audio quality, relative audio/video ruggedness and delay, and system re-synchronisation time. Associated developments in statistics will also be undertaken, both for the purposes of picture content analysis and also for the processing and presentation of results. Technical Approach The methods employed in MOSAIC are largely those of the psychologist, based around a number of carefully designed experiments. The results need to be skilfully interpreted in the light of statistical analyses. It is only after novel ideas have been experimented with and refined, that new methods for the assessment of picture quality will emerge. In this way the project will: 

- Develop accurate tools to specify, optimise and evaluate image communication systems.
- Support other European projects with an assessment methodology for the evaluation of image compression systems.
- Contribute towards new ITU picture quality and degradation assessment procedures. 

Key Issues 
- Assessment Methodology.
- Assessment of Scene Dependent Quality.
- Influence of Audio on Subjective Video Quality.
- System Parameters and Viewing Conditions. 

Expected Impact 
The new tools developed by the MOSAIC project will allow the developers of image transmission systems to make scientifically-based evaluations of their systems and to compare in a meaningful manner the relative performance of the various systems.
This work will be disseminated through a handbook and a workshop in autumn 1995.
