摘要： A method for evaluating video quality of a video stream comprising the steps of
a) calculating, for at least a first frame of a series of frames from said video stream, a true value of at least one video quality-related parameter associated to said first frame;
b) calculating a predicted value of said video quality-related parameter for at least a second frame from said series of frames based on said true value associated to said first frame;
c) calculating a true value of said video quality-related parameter associated to said second frame; and
d) judging the video quality of said second frame based on a difference between true and predicted values of the at least one video quality-related parameter associated to said second frame.摘要翻译： 一种用于评估视频流的视频质量的方法，包括以下步骤：a）对于来自所述视频流的一系列帧的至少第一帧，计算与所述第一视频流相关联的至少一个视频质量相关参数的真实值 帧; b）基于与所述第一帧相关联的所述真实值，从所述一系列帧计算至少第二帧的所述视频质量相关参数的预测值; c）计算与所述第二帧相关联的所述视频质量相关参数的真实值; 以及d）基于与所述第二帧相关联的所述至少一个视频质量相关参数的真实值和预测值之间的差异来判断所述第二帧的视频质量。
