Problems solved by technology

[0004] For the extraction of highlight clips, it is usually based on a manual method, and the points are embedded in the video to be processed in advance. For example, the appearance time of the highlight clips is manually pre-marked. Time cost, the extraction efficiency is low, and there is a strong subjective influence on the extraction of highlights, different extractors often extract different highlights, and the accuracy is low

Abstract

The embodiment of the invention discloses a method and device for obtaining wonderful clips in a video, electronic equipment and a storage medium. The method comprises the steps: obtaining a pluralityof original image frames of a to-be-processed video, and respectively extracting image features from each original image frame; obtaining a plurality of differential feature values of the to-be-processed video according to the image features of the original image frames; determining a plurality of wonderful image frames in the to-be-processed video according to the difference characteristic values, and determining wonderful clips of the to-be-processed video according to the wonderful image frames. According to the technical scheme of the embodiment of the invention, the wonderful segment inthe video is extracted through the computer, the manpower extraction cost and the time extraction cost are saved, the extraction efficiency is improved, the wonderful image frame with bright color isdetermined according to the difference feature value based on the image feature, the subjective influence of an extraction person is avoided, and thus the extraction accuracy of the wonderful fragments is relatively low.

Description

technical field [0001] Embodiments of the present disclosure relate to video processing technologies, and in particular, to a method, device, electronic device, and storage medium for acquiring highlights in a video. Background technique [0002] With the continuous development of Internet technology, a variety of video software appears on terminal equipment, which brings a large amount of video data, and video extraction technology, as a commonly used video data processing method, has become a video processing technology. important branch. [0003] A fully recorded video is difficult to fully display due to its long duration. Usually, one or more highlights will be extracted from the video to reflect the highlights of the video. It can also be updated without taking up too much viewing time of the user. Quickly attract users' attention. [0004] For the extraction of highlight clips, it is usually based on a manual method, and the points are embedded in the video to be pr...
