Abstract :
This paper is devoted to discriminate pixel difference in the context of visual signal for picture quality prediction, according to human perceptual characteristics. The new quality predictor as the result of the analysis remedies one oversight in all the previous metrics, and proves to be more accurate and consistent in visual quality prediction then the best metrics in the VQEG tests.
