Comments on Objective Quality Assessment of MPEG-2, H.264 and H.265 Videos
This paper presents the performance analysis of five full-reference objective quality assessment measures on compressed high-resolution video sequences from two publicly available video datasets. Quantitative measures that were accepted by the international research community used in the performance analysis - the correlation coefficient of ranks and the linear correlation coefficient between subjective and objective quality scores. The performance analysis is carried out globally - the level of complete datasets and on subsets of sequences with common characteristics (compression type or source sequence). Three types of compressed video content were analyzed - H.265 and its predecessors H.264 and MPEG-2. The correlation between subjective and objective quality scores is analyzed in different scales (resolutions) of the video signal. From the analysis of the results, very important conclusions on the objective quality assessment of the compressed video signals were derived, as well as the directions for further work.
