Popis: U ovom radu detaljno su opisane pojedine baze za subjektivno ocjenjivanje videa kvalitete, te su dodatno za 3 baze provedena testiranja kvalitete PSNR metrikom. Za te odabrane baze vršilo se testiranje kvalitete u programu MSU Video Quality Measurement tool. Za svaku pojedinu bazu su se u programu usporeĎivali izobličeni video zapisi s referentnim video zapisima dobivenim u toj bazi. Pri završetku testiranja, računao se Pearsonov linearni koeficijent korelacije kako bi se utvrdilo odstupanje objektivnog ocjenjivanja od subjektivnog ocjenjivanja kvalitete, te su prikazani dobiveni rezultati. In this paper there is detailed description for each of subjective quality databases provided by the researchers, and three of them were tested by the PSNR metric. For selected databases we used MSU Video Quality Measurement tool to test the quality of the video. In each database we compared distorted videos with original sequences. After the testing phase, we used Pearson linear correlation coefficient formula, so that we could check the deviation between results. Results we obtained by testing are described in the paper.
