English abstract:
In this paper we propose a subjective quality predictor for
damaged low resolution H.264/AVC encoded sequences. The
predictor utilizes the information relayed by a visual artifacts
detection algorithm working at pixel level and is supported by
a syntax analysis error detector working at bit level. The algorithm
is capable of predicting the Mean Opinion Score (MOS)
of the received damaged sequence. Preliminary results show
a strong correlation between the predicted data and subjective
measurement tests with volunteers. Such a method could be
used over video transmissions in error-prone channels, such
as in wireless systems to adjust the transmission to the estimated
received subjective quality.
