Abstract

The present application provides a method and device for evaluating video quality. The method for evaluating video quality includes: extracting an image frame to be evaluated from a video to be evaluated; using a preset image definition algorithm to calculate the clarity of the image frame to be evaluated. resolution; statistically counting the proportions of image frames whose resolution is greater than a preset resolution threshold in the video to be evaluated, and evaluating the quality of the video to be evaluated based on the proportion. The efficiency of video quality evaluation can be improved.

Description

technical field [0001] The present application relates to the technical field of quality evaluation, in particular, to a method and device for evaluating video quality. Background technique [0002] At present, with the popularization of communication networks, the number of video uploads and downloads through the communication network is very large every day. However, due to the uneven quality of videos uploaded by different users, even for different videos containing the same content, the browsing time of videos is very high. User experience also varies widely. Among them, definition, as an important indicator of video quality, has a very intuitive impact on the user's video browsing experience. Therefore, if the user can know the quality evaluation of the video before downloading the corresponding video, the user's video browsing experience can be effectively improved. [0003] At present, the video quality assessment is generally carried out manually, that is, the video...
