Embodiment approach

[0166] As an optional implementation, the extraction module includes:

[0167] (1) The fifth determination sub-module is used to sequentially determine the second threshold corresponding to the key frame to be extracted of the current shot, wherein the second threshold is between all video frames in the current shot and all extracted key frames of the query video The weighted sum of the mean and variance of the distances between

[0168] (2) The sixth determination submodule is used to determine the degree of attention change of each first video frame of a plurality of first video frames of the current shot, wherein the plurality of first video frames are all extracted key frames in the current shot The average value of the distance between is greater than or equal to the video frame of the second threshold value, and the degree of attention of each first video frame changes as the sum of the difference between the pixels corresponding to each first video frame and the second ...

Abstract

The invention provides a video copy detection method and device, a storage medium and an electronic device. The method comprises the following steps: extracting a first target key frame of a query video; extracting a first video feature of the first target key frame; acquiring a second video feature of a second target key frame of the reference video; and when it is determined that the query video is matched with the reference video according to the first video feature and the second video feature, extracting similar video clips in the query video and the reference video. The problems of low video copy detection efficiency and poor video copy detection accuracy in a video copy detection method in the related technology are solved, and the effects of improving the video copy detection efficiency and improving the video copy detection accuracy are further achieved.

Description

technical field [0001] The present application relates to the computer field, and in particular to a video copy detection method and device, a storage medium and an electronic device. Background technique [0002] With the rapid development of Internet technology and multimedia technology, the number of videos on the network is also increasing rapidly. People can edit or modify videos and produce some copied videos through some digital video processing tools. After these copied videos are published on the Internet, users can get many videos with similar or even the same content when searching for videos, which greatly reduces the efficiency of retrieval and seriously violates the legitimate rights and interests of copyright owners. [0003] In order to improve retrieval efficiency and protect the legitimate rights and interests of copyright owners, similar video retrieval can be performed on videos posted by users before users post videos. Video copy detection can be perfor...
