Subjective Video Quality Assessment Using Single and Double Stimulus Methods
Abstract
Subjective Video Quality Assessment Using Single and Double Stimulus Methods
Stefan Brachmański, Janusz Klink, Michał Łuczyński
The article presents the results of video quality assessment using two methods recommended by the International Telecommunication Union. These are the Single Stimulus (SS) and the Double Stimulus Impairment Scale (DSIS) methods. The results obtained by both methods were compared. The studies were performed for two coding techniques, H.264 and H.265, and for spatial resolutions of 1280 × 720 and 1920 × 1080. The studies showed a very high correlation between the MOS values obtained by SS and DSIS methods for H.265 coding and both video resolutions. Regarding the H.264 coding, a very good consistency of the results was obtained for bitrates starting from 3000 kbps.
