Abstract

Reliably predicting how humans assess video quality aspects remains an academic challenge, partly due to our limited understanding of human visual system and of how it affects the perception of spatial and temporal distortions. In current video chains, the perceived quality varies over time, depending on the compression level and video content. However, the impact of both factors on the extent of such variation is unknown, while this knowledge would be highly beneficial for video quality modeling. In this paper, a perception experiment is conducted with human observers rating the quality and meanwhile the extent of quality variation over time (QVT) for a set of video sequences. Preliminary results show that QVT tends to be less observed in the low and high quality regions; and that QVT seems to be sensitive to video content independent of compression level
