Analysis of Temporal Effects in Quality Assessment of High Definition Video
MetadataShow full item record
The paper deals with the temporal properties of a~scoring session when assessing the subjective quality of full HD video sequences using the continuous video quality tests. The performed experiment uses a modification of the standard test methodology described in ITU-R Rec. BT.500. It focuses on the reactive times and the time needed for the user ratings to stabilize at the beginning of a video sequence. In order to compare the subjective scores with objective quality measures, we also provide an analysis of PSNR and VQM for the considered sequences to find that correlation of the objective metric results with user scores, recored during playback and after playback, differs significantly.
