面向 UHDTV 的多分辨率视频显示质量评估研究
Evaluation of display quality on UHDTV for multi-resolution videos
摘要
Abstract
Ultra High Definition Television (UHDTV)has been gaining popularity with its ultrahigh screen definition.However,the lack of Ultra HD resources usually leads to the result that the videos played on UHDTV are up-scaled,which may affect the display quality of the videos.Until now,there are few researches on UHDTV video display quality.In this paper,the SSIM algorithm is employed to evaluate the video coding quality,then the effects of video resolution on display quality are analyzed according to the results of the subjective experiment,and finally a video quality assessment model is proposed for UHDTV service.Experimental results and comparisons with the classic SSIM,VIFp and MOVIE metrics show that the proposed model gets increments of 1.13%,1.89% and 2.31% in PCC, increments of 1.35%,1.53% and 2.24% in SRCC,and decrements of 35.05%,36.94% and 39.71% in RMSE,respectively.Thus,the proposed model can be used to estimate the video display quality on UHDTV more accurately.关键词
