Video quality objective metric using data hiding

In this paper a non-reference objective video quality metric is proposed. The quality metric is obtained by means of a non-conventional use of data hiding technique. Test data are embedded in an MPEG-2 video; the basic assumption is that the data embedded undergo under the same degradation as the host video. To analyze the performance of the system, a comparison between the results obtained using this metric and the perceived mean annoyance values was performed. The annoyance values were obtained through a psychophysical experiment, which measured the threshold and mean annoyance values of compressed videos.
