About the imperfection of objective quality metrics on high-definition video content

摘要

Due to the ever-growing importance of video content delivered through today's Internet, not only the availability of high-definition video material but also its high quality must be guaranteed. The latter can be achieved by means of objective video quality metrics. Recently, insufficient quality prediction accuracy for well-known full-reference objective quality metrics on high-definition video content has been reported. With this paper we aim at identifying possible reasons for the observed imperfection.
