Abstract
The Video Quality Experts Group (VQEG) is a group of experts from industry, academia, government and standards organizations working in the field of video quality assessment. Over the last 10 years, VQEG has focused its efforts on the evaluation of objective video quality metrics for digital video. Objective video metrics are mathematical models that predict the picture quality as perceived by an average observer. VQEG has completed validation tests for full reference objective metrics for the Standard Definition Television (SDTV) format. From this testing, two ITU Recommendations were produced. This standardization effort is of great relevance to the video industries because objective metrics can be used for quality control of the video at various stages of the delivery chain. Currently, VQEG is undertaking several projects in parallel. The most mature project is concerned with objective measurement of multimedia content. This project is probably the largest coordinated set of video quality testing ever embarked upon. The project will involve the collection of a very large database of subjective quality data. About 40 subjective assessment experiments and more than 160,000 opinion scores will be collected. These will be used to validate the proposed objective metrics. This paper describes the test plan for the project, its current status, and one of the multimedia subjective tests.
