Subjective video quality evaluation for multimedia applications

Modelling of spatio–temporal interaction for video quality assessment

“…We selected the ACR method based on the results of previous studies, which have shown that this method is reliable for assessing the quality of low-resolution videos encoded at low bit rates and exhibiting both spatial and temporal distortions [20][21][22][23]. The ACR method with a 5-point discrete scale was used by the Video Quality Experts Group (VQEG) to conduct their evaluation of objective quality assessment models for low-resolution videos [24].…”

Investigation of the effectiveness of video quality metrics in video pre-processing

“…[18,19] are the most widely adopted video quality evaluation strategies. The subjective quality of these videos is evaluated using Absolute Category Method (ACM) because of its ability to obtain repeatable results during the subjective evaluation [20][21][22]. These tests are carried out in a standard test environment with 60 non-expert viewers so that each of these 100 sequences is subjectively rated by 10 non-expert viewers.…”
