4-7 方式変換映像の遠隔画質監視手法の高精度化(第4部門 中継・放送と障害監視技術)

抄録

As remote quality monitoring methods for standard-converted video are needed, we previously proposed a scheme that combines subsampling and the SSSWHT-RR (spread spectrum and WHT coefficients extraction) method. This paper proposes to improve its accuracy using video signal variance and correlation coefficients.
