Abstract

The embodiment of the invention discloses a video deduplication scheme. The video deduplication scheme comprises the steps of obtaining a first video; extracting a plurality of images from the first video according to a set sampling rule, wherein the scene transformation fragment with higher scene transformation intensity in the first video corresponds to higher sampling frequency; for each imagein the plurality of images, extracting image feature information of the image; sorting the plurality of image feature data corresponding to the plurality of images according to the appearing sequenceof the plurality of images in the first video to obtain first video feature data of the first video; and comparing the first video feature data corresponding to the first video with at least one second video feature data obtained by at least one second video according to the same method, and determining the similarity between the first video and any one second video in the at least one second video. According to the scheme of the embodiment, the computing power can be arranged more reasonably on the premise of ensuring the duplicate removal accuracy.

Description

technical field [0001] The present application relates to the field of video processing, in particular to a video deduplication method and device. Background technique [0002] With the development of Internet technology and industry, in addition to traditional TV stations, video websites and short video platforms have become new storage platforms for massive media resources, and millions of video bloggers have emerged to participate in content creation. Among them, it often happens that the content uploaded by the user already exists in the video library. If the video platform cannot find it, it will not only waste storage space, but also bury a great hidden danger for future copyright disputes. [0003] Therefore, it is necessary to compare the newly uploaded video with the existing videos in the platform video library to avoid repeated uploads. There are mainly the following ways to achieve this: [0004] 1) Extract video key frames from the video in the video library, s...
