【摘要】：目前,对视频业务体验质量(QoE)的客观评估方法中,视频图像质量下降造成的可见显示损伤持续时间对用户体验质量的影响往往被忽略。针对该问题,讨论了可见显示损伤持续时间对用户体验质量的影响。同时,分析了造成可见显示持续损伤的客观原因,构建了包含分层客观指标和主观评估结果的贝叶斯网络。在此基础上,提出了针对视频业务体验质量的无参考评估方法,并通过主观测试验证了该方法的准确性。
[Abstract]:At present, in the objective evaluation method of video service experience quality (QoS), the effect of visual display damage duration caused by video image quality degradation on user experience quality is often ignored.Aiming at this problem, the effect of visible display injury duration on user experience quality is discussed.At the same time, the objective causes of visible and continuous damage are analyzed, and a Bayesian network is constructed, which includes hierarchical objective indexes and subjective evaluation results.On this basis, a non-reference evaluation method for video service experience quality is proposed, and the accuracy of the method is verified by subjective test.
