Abstract

The invention discloses a video definition detection method and device, a computing device and a computer storage medium. The method is executed based on a trained feature extraction network and a trained video definition detection model, and includes: obtaining a to-be-detected video file; inputting the to-be-detected video file into the feature extraction network to obtain a preset dimensional file feature corresponding to the to-be-detected video file. The method and device greatly save time, improve the efficiency and accuracy of feature extraction, can avoid the influence of false video meta information, detect the definition by using the video definition detection model based on the preset dimensional file feature so as to obtain a definition value corresponding to the video file, achieve automatic file detection, save the required detection time, and reduce labor cost. Since the influence of false video meta information can be avoided, the accuracy of video definition detectionis improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video definition detection method, device, computing equipment and computer storage medium. Background technique [0002] Video clarity is an important indicator that affects video viewing experience. Factors that cause the video to be unclear include: video resolution is too low, video bit rate is too low, video is too dark or too bright, video is too jittery, etc. At present, the Internet is flooded with a large number of unclear and low-quality videos. The existing video definition evaluation methods mainly include the following: [0003] (1) Manual review. Manually reviewing whether the video is clear or not requires a lot of labor costs, and it takes a long time to review the video; [0004] (2) Review based on video meta information. Video meta information includes information such as resolution and bit rate. There are a large number of videos that us...
