A reduced reference picture quality measure is proposed for MPEG-2 compressed videos. The measure can be calculated from the ratio of three N tap one-dimensional discrete cosine transform (DCT) coefficients. The proposed measures are highly correlated to subjective test scores and can provide accurate assessment of picture quality for a certain type of sequences.
