Paper Abstract

We propose a PQSvideo (Picture Quality Scale for moving image), a method of objective quality assessment for coded moving images. We expect that the proposed PQSvideo approximates subjective assessment well. In PQSvideo, we define essential distortion factors considering not only global distortions (such as random noise) but also distortions on local features. Then, we describe each distortion metrically considering human visual perception. The PQSvideo is given by a linear combination of define each essential distortion factor, utilizing the principal component analysis method and the multiple regression analysis method between quantity of each essential distortion factor and MOS (Mean Opinion Score) obtained by assessment test. We have confirmed that the PQSvideo approximates MOS successfully.
