No-reference video quality estimation based on error-concealment effectiveness
Tōru Yamada, Yoshihiro Miyamoto, Masahiro Serizawa · 2007
This paper proposes a no-reference videoquality estimation method for monitoring end-user video quality. It is suitable for applications to video transmitted over IP networks. IP network conditions vary for individual users, and assuring end-user video quality is an important issue. To do this, it is necessary to monitor video quality at end-user terminals. With the proposed method, video quality is estimated on the basis of the number of macroblocks containing errors which it has not been possible to conceal. Error concealment effectiveness is evaluated using motionlevel information and luminance discontinuity at the boundaries of error regions. Simulation results show a high correlation (0.95) between the actual mean square error and the number of macroblocks in which complete error concealment has not been possible.
