Video retrieval method and device, computer equipment and storage medium

Abstract

The invention relates to a video retrieval method and device, computer equipment and a storage medium, and belongs to the technical field of computers. The method includes: extracting frame features of multiple first video frames of a to-be-retrieved video; acquiring n candidate videos on the basis of the frame features of the multiple first video frames and preset first correspondence relationships, wherein the first correspondence relationships record videos and video frames corresponding to each of the multiple frame features, the videos in the first correspondence relationships are m videos stored in a video library, each of the m videos includes multiple second video frames, and n<m; and determining target videos, of which degrees of similarity with the to-be-retrieved video are greater than a preset threshold value, in the n candidate videos. According to the method, problems that in the related art, video features of each video in a video library and a similarity degree of the video features of each video and video features of a to-be-retrieved video need to be calculated, a calculation amount is larger, and retrieval efficiency is lower are solved, a calculation amount is decreased, and retrieval efficiency is improved. The method is used for video retrieval.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a video retrieval method and device, computer equipment, and storage media. Background technique [0002] With the rapid development of the Internet and digital technology in recent years, it has become easier and easier to obtain video content. As one of the very important technologies, video retrieval technology has received extensive attention. Through video retrieval technology, it can be found from a large number of videos stored in the video library. Videos similar to the video in question. [0003] In the related art, the video features of each video in multiple videos of the video library and the video features of the video to be checked are usually first extracted, and then the similarity between the video features of each video and the video features of the video to be checked is calculated, and finally the A video whose similarity with the video features of the vide...
