Monitoring the quality of MPEG coded video

A novel two-stage video distortion meter exploring the psychological aspect of human beings is proposed. The first stage is a distortion weighting stage, where picture artifacts are weighted according to their visibility. The second stage, denoted the Cognitive Emulator, simulates the psychological effect of time-varying picture quality on the judgement process of human observers. Experimental results show that with the cognitive emulator, one can predict the result that would be obtained using otherwise the SSCQE methodology for video sequences.
