Abstract

The invention discloses a video quality evaluation method, device, medium and terminal. The method includes acquiring sample videos, and preprocessing each of the sample videos to obtain a corresponding reference video. The reference video includes sample video segments and Marking a video segment, the video data in the sample video segment points to the sample video corresponding to the reference video; inputting the reference video into the video processing system; intercepting the video to be analyzed at the output end of the video processing system, the video to be analyzed Include the target video; determine the marked video segment in the to-be-analyzed video, and determine the to-be-evaluated video segment according to the marked video segment; perform full reference to the to-be-evaluated video segment according to the sample video segment of the reference video Quality Evaluation. The present invention can perform full reference quality evaluation according to the frame alignment result without invading the video processing system, can be applied to various scenarios, and can achieve the accuracy of full reference quality evaluation.

Description

technical field [0001] The present invention relates to the field of video quality evaluation, in particular to a video quality evaluation method, device, medium and terminal. Background technique [0002] In the prior art, the video processing system can perform at least one kind of processing such as acquisition, transmission, streaming, codec, and playback of the video, and video quality loss may occur in each processing link, so it is necessary to process the video through the video processing system. Objectively and accurately evaluate the quality of the video in order to accurately grasp the performance of the video processing system in maintaining the stability of the video quality. Two methods for evaluating video quality are mainly proposed in the prior art. [0003] The first method is to add the underlying interface to the existing video processing system, directly obtain the pre-processed video as a reference, and directly obtain the video to be tested at the ou...
