Higer value of MOS (0 - minimal, 9 - maximal, MSE of each score Or 1048680 evaluations of relative visual quality in image pairs. Performed 524340 comparisons of visual quality of distorted images (116 experiments have been carried out in Finland, 72 in France, 80 in Italy,Ħ02 in Ukraine, and 101 in USA). ![]() Observers from five countries: Finland, France, Italy, Ukraine and USA The MOS was obtained from the results of 971 experiments carried out by The file "mos.txt" contains the Mean Opinion Score for each distorted image.
