Abstract
In this paper, we propose an objective picture quality scale (PQSvideo) for video coding based on the MC + DCT coding algorithm. We employ average and maximum of several essential distortion factors such as Flicker, Jerky movement, Deformation of moving object and Mosquito noise, which are calculated from each frame of video sequence. For constructing PQSvideo, a principal component analysis is carried out to eliminate the correlation between distortion factors. Then, by assuming the linear combination model between principal components and Mean Opinion Score (MOS), the combination coefficients can estimate by a multiple regression analysis. PQSvideo closely approximates the MOS, with a correlation coefficient of more than 0.98 and a maximum absolute error is less than 0.43.
