A perceptual measure to predict the visual distinction between two color images

This paper presents a perceptual model to predict the visual distinction be tween a pair of color images which correlates well with the human observer' s evaluation. Its basic assumptions are to be in agreement with spatial-fre quency channels models quite successful for the detection of Visual pattern s. The model was applied to predict the perceived quality of a basic patter n as well as the visibility of the artifacts in JPEG reconstructions. The r ank order produced by the PID error and other quantitative measure are comp ared with the reference rank order as given by a subjective rating performe d by photointerpreters.
