Abstract

Disclosed are a method and device for valuating quality of a video in a time domain on a terminal side. The method comprises that: a significant movement area proportion of each video frame is calculated, video frames are divided into absolute regular frames and suspected distorted frames according to the significant movement area proportion of each video frame; a frozen frame detection, a scenario-conversion frame detection, a jitter frame detection, and a ghosting frame detection are performed on the suspected distorted frames; the video is split into scenarios according to the result of the scenario-conversion frame detection, scenario information weight of each scenario is calculated, and the quality of the video in time domain on the terminal side is determined. The present disclosure solves the problems for the no-reference technology in time domain on the terminal side in the related art that the evaluation error is big, the movements is overlooked, and the indicator is single, thus increasing the closeness of the evaluation result to subjective perception, expanding an evaluation system of time domain distortions of the video, and reducing the probability of misjudgments.

Description

technical field [0001] The present invention relates to the technical field of video objective quality evaluation, in particular to a terminal-side time-domain video quality evaluation method and device. Background technique [0002] In the prior art, the objective quality evaluation of video can be implemented on the network side and the terminal side respectively, wherein the evaluation on the terminal side is performed after the user terminal decodes the video. Although it is not as good as the evaluation on the network side in terms of efficiency and feedback ability, it evaluates the video that the user finally watches, which can fully reflect the impact on video quality from service to network, finally to terminal reception, and video decoding. Reflect the user's subjective experience of video services. [0003] The temporal domain quality of a video refers to the quality factor that only exists between video frames, that is, the impact of the loss of an entire frame ...
