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. |
