Abstract

The invention discloses a video abstract extraction method, a video abstract extraction system, a video abstract extraction device and a storage medium. Different frame image feature extraction algorithms are sequentially used for hierarchical clustering from small to large according to time consumption, frame images needing to be processed are reduced layer by layer, finally, global features areextracted from candidate video abstracts proposed for each obtained segmented video clip, and a final video abstract is generated. Compared with an existing method, the method does not need to consider different feature weight problems, time consumption is greatly reduced, and the method has the advantages of being good in robustness, high in speed and good in effect.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method for extracting video summaries based on multi-feature similarity and its system, device and storage medium. Background technique [0002] At present, with the emergence of many video apps and simple video editing tools, a large number of videos uploaded by users have begun to appear in large numbers. Under normal circumstances, the time people spend watching videos is consistent with the video duration. This leads to a problem. On today's websites or software with a large number of videos, how can users quickly and accurately find the part they are interested in through the correct video summary and how to quickly classify the videos uploaded by users and classify them correctly? Under different indexes, it becomes a valuable research problem. The rapid increase in the number has provided the enthusiasm for research, and it has also made video classific...
