Objective quality measures assessment

A study was performed to assess the ability of five objective quality measures to predict perceptual quality difference ratings. The objective measures included peak signal-to-noise ratio (PSNR), root-mean-square error (RMSE), maximum absolute difference (MAD), the Image Quality Metric (IQM), and the just-noticeable-difference (JND) metric. Perceptual difference ratings used the National Image Interpretability Rating Scale (NIIRS). NIIRS data from four previous studies of bandwidth compression and image processing were compared to values of the five objective measures to determine whether any of the objective metrics could be used as a substitute for the labor-intensive NIIRS ratings.
