Subjective Quality Assessment of H.264/AVC Video Streaming with Packet Losses
Résumé
Research in the field of video quality assessment relies on the availability of subjective scores, collected by means of experiments
in which groups of people are asked to rate the quality of video sequences. The availability of subjective scores is fundamental
to enable validation and comparative benchmarking of the objective algorithms that try to predict human perception of video
quality by automatically analyzing the video sequences, in a way to support reproducible and reliable research results. In this
paper, a publicly available database of subjective quality scores and corrupted video sequences is described. The scores refer to 156
sequences at CIF and 4CIF spatial resolutions, encoded with H.264/AVC and corrupted by simulating the transmission over an
error-prone network. The subjective evaluation has been performed by 40 subjects at the premises of two academic institutions,
in standard-compliant controlled environments. In order to support reproducible research in the field of full-reference, reduced reference,
and no-reference video quality assessment algorithms, both the uncompressed files and the H.264/AVC bitstreams, as
well as the packet loss patterns, have been made available to the research community.
