Abstract

The invention discloses a terminal side time-domain video quality evaluation method and apparatus. The method comprises: calculating the remarkable motion area proportion of each video frame, each remarkable motion area proportion referring to the proportion which a remarkable changing area between two neighboring video frames takes up in one video frame area; according to the remarkable motion area proportions, dividing all the video frames into absolute common frames and suspected distortion frames; performing freeze frame detection, scene conversion frame detection, jitter frame detection and ghosting artifact frame detection on the suspected distortion frames; and according to scene conversion frame detection results, performing scene segmentation on a video, calculating the scene information weight of each scene, calculating distortion coefficients according to freeze frame detection results, jitter frame detection results and ghosting artifact frame detection results, and determining terminal side time-domain video quality according to the remarkable motion area proportions, the scene information weights and the distortion coefficients.

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 ...
