摘要：
This paper presents a perceptual image quality assessment metric based on the Visible Differences Predictor (VDP) proposed by Daly. The proposed metric operates in two modes. In a quality mode, the metric produces a single value representation of the overall visible image quality (VIQ), whereas in a distortion mode, the metric provides four distortion values each associated to a specific type of image content. The correlation coefficient between the objective VIQ and subjective test results is 0.96, compared to 0.86 obtained by the PSNR measure.
