Evaluation of coding efficiency is traditionally modeled as a continuous rate-distortion (R-D) function, where the peak signal-to-noise ratio (PSNR) is adopted as the quality measure. Although the PSNR-versus-bitrate curve offers some useful tradeoff information between video quality and coding bit-rates, it does not take human perceptual experience into account. In this work, by following the recent...
A new video quality index, called the distortion/content-dependent video quality index (DCVQI), is proposed in this paper. The distortion and content effects on video quality assessment are taken into account explicitly in the DCVQI. First, we classify distortions into two types (local and global distortions) with a distortion classification scheme. Then, for a given distortion type, we observe a...
