Problems solved by technology

The edited video will bring great difficulties in detection. Compared with the traditional video detection method, the detection accuracy of the traditional method is low, the algorithm is more time-consuming, the detection time is longer, and the video image may not be found. And other problems, ultimately unable to meet the needs of users

Embodiment Construction

[0068] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0069] The invention provides a method for detecting video plagiarism, comprising the following steps:

[0070] Step S1, the video to be tested is decomposed into each frame image of the video to be tested by a decoding algorithm, and each frame image of the video to be tested and its total number of frames are output;

[0071] Step S2, using the multi-frame difference method to extract video key frames of the video to be tested;

[0072] Step S21, each frame image f of the input video k (x, y), the adjacent two frames of images are subtracted by the subtractor and take the absolute value, the mathematical expression is:

[0073] f k差 (x,y)=|f k (x,y)-f k-1 (x,y)|

[0074] Step S22, the difference obtained in step S21 is multiplied by a multiplier to obtain an inter-frame difference image D k (x,y), the mathematical expression is: ...

Abstract

The invention relates to a video plagiarism detection method and system. According to the method and system, a multi-frame difference method is combined on the basis of a difference hash image recognition algorithm, key frames of a video to be detected can be accurately extracted, and the problems that a single traditional hash algorithm is low in image processing accuracy, long in algorithm running time and the like are solved. The multi-frame difference method adopted by the invention is improved on the basis of the traditional inter-frame difference method, and compared with the traditionalalgorithm for extracting the video key frame, and the defect that only the boundary part can be extracted and the relatively complete region cannot be extracted is overcome. According to the method,a multi-frame difference method and a difference hash algorithm are combined, and the effect of extracting the video key frames in the aspects of frame number, accuracy and algorithm running time is optimal.

Description

technical field [0001] The invention is applied in the technical field of video detection, and in particular relates to a method and system for detecting video plagiarism. Background technique [0002] With the development of computer network and video processing technology, all kinds of video editing software are easy to learn nowadays, such as: love editing, quick editing, vivid video, etc. Many novice users can edit and modify the original video in a short time. This greatly increases the possibility of video plagiarism, followed by issues such as infringement disputes and commercial disputes. Video plagiarism refers to given a number of video clips to be tested, searched in the existing video database, or compared with source videos known to be plagiarized, to detect whether there are similarities between the video to be tested and the source video or video library. Video clip content. If it exists, the video to be tested can be identified as video plagiarism. Nowaday...
