Abstract

The invention is applicable to the technical field of multimedia information processing, and provides a video copy detection method and system thereof. The method comprises the following steps: obtaining an image tag Y in the image training set; carrying out copy attack on each image tag Y to obtain a first image X. The training model of depth feature extraction model is constructed, and the depthfeature extraction model is obtained by training. Obtaining a first fusion feature after fusing the first depth feature and the first DCT coefficient feature of each second image, and storing the first fusion feature as a fusion feature database; Extracting a third key frame of the query video, and fusing the second depth feature and the second DCT coefficient feature to obtain a second fusion feature; Each of the second fusion features is matched with each of the first fusion features to obtain a detection result of the query video. Thus, the invention improves the discrimination and robustness of the video features and improves the accuracy of the video copy detection system.

Description

technical field

[0001] The invention relates to the technical field of multimedia information processing, in particular to a video copy detection method and system thereof. Background technique

[0002] With the development of science and technology and the widespread popularization of the Internet, the problem of digital video piracy has become increasingly prominent. The content-based video copy detection technology is a method to judge whether the video to be detected constitutes piracy and infringement by comparing the similarity between the video to be detected and the original video. , video infringement includes not only copying the original video, but also zooming, cropping, rotating, blurring, inserting text or graphics and other operations on the video. Content-based video copy detection is crucial to video copyright protection and management effect.

[0003] Traditional video copy detection techniques are mainly divided into methods based on global features and m...
