“…The former are detected using a combination of the quantization step size and scene activity whereas the latter are detected during error concealment. Therefore, the AVQ metric requires access to both the network bitstream and the decoded video sequence [34].…”

“…In 2D videos, video quality is either measured using objective metrics such as mean square error or subjective metrics such as mean opinion score and mean time between failures [2]. However, measuring 3D video quality poses additional challenges due to the third dimension of depth that is perceived by the human brain.…”
