摘要

本文提出了一种基于可见差异预测器(VDP)的感知图像质量评估度量(Daly, 1993)。所提出的度量以两种模式运行。在质量模式下，度量产生整体可见图像质量(VIQ)的单个值表示，而在失真模式下，度量提供四个失真值，每个值与特定类型的图像内容相关。客观VIQ与主观测试结果的相关系数为0.96，而PSNR测量结果为0.86。

Dual-mode image quality assessment metric

This paper presents a perceptual image quality assessment metric based on the visible differences predictor (VDP) (Daly, 1993). The proposed metric operates in two modes. In quality mode, the metric produces a single value representation of the overall visible image quality (VIQ), whereas in distortion mode, the metric provides four distortion values each associated with 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.
