摘要： Systems and methods of objective video quality measurement that employ a reduced-reference approach to video quality measurement. Such systems and methods of objective video quality measurement can extract information pertaining to one or more features of a target video whose perceptual quality is to be measured, extract information pertaining to one or more features of a reference video, and employ one or more prediction functions involving the target features and the reference features to provide a measurement of the perceptual quality of the target video.
摘要翻译：使用缩减参考方法进行视频质量测量的客观视频质量测量的系统和方法。客观视频质量测量的这种系统和方法可以提取关于感知质量要被测量的目标视频的一个或多个特征的信息，提取与参考视频的一个或多个特征有关的信息，并采用一个或多个预测函数涉及目标特征和参考特征以提供目标视频的感知质量的度量。

摘要： Systems and methods of perceptual quality monitoring of video information, communications, and entertainment that can estimate the perceptual quality of video with high accuracy, and can be used to produce quality scores that better correlate with subjective quality scores of an end user. The systems and methods of perceptual quality monitoring of video can generate, from an encoded input video bitstream, estimates of one or more quality parameters relating to the video, such as the coding bit rate parameter, the video frame rate parameter, and the packet loss rate parameter, and provide these video quality parameter estimates to a predetermined video quality estimation model. Because the estimates of the video quality parameters are generated from the encoded input video bitstream as it is being received, the systems and methods are suitable for use as QoE monitoring tools.
摘要翻译：视频信息，通信和娱乐的感知质量监控的系统和方法可以高精度地估计视频的感知质量，并且可以用于产生与最终用户的主观质量得分更好相关的质量分数。视频的感知质量监视的系统和方法可以从编码的输入视频比特流中产生与视频相关的一个或多个质量参数的估计，例如编码比特率参数，视频帧速率参数和分组丢失速率参数，并将这些视频质量参数估计提供给预定的视频质量估计模型。因为视频质量参数的估计在编码的输入视频比特流被接收时产生，所以系统和方法适合用作QoE监视工具。
