【摘要】：目前,對視頻業(yè)務(wù)體驗質(zhì)量(QoE)的客觀評估方法中,視頻圖像質(zhì)量下降造成的可見顯示損傷持續(xù)時間對用戶體驗質(zhì)量的影響往往被忽略。針對該問題,討論了可見顯示損傷持續(xù)時間對用戶體驗質(zhì)量的影響。同時,分析了造成可見顯示持續(xù)損傷的客觀原因,構(gòu)建了包含分層客觀指標(biāo)和主觀評估結(jié)果的貝葉斯網(wǎng)絡(luò)。在此基礎(chǔ)上,提出了針對視頻業(yè)務(wù)體驗質(zhì)量的無參考評估方法,并通過主觀測試驗證了該方法的準(zhǔn)確性。
[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.
