The invention discloses a video plagiarism detection method based on a sliding window, and the method comprises the steps: obtaining at least one bottom library video and a query video, and selectingat least one bottom library video as a candidate video; and forming a matching video pair by the query video and each candidate video, and constructing a similarity matrix image of each matching videopair; acquiring a detection sliding window, sliding the detection sliding window on the similarity matrix image according to a preset sliding track, and recording a detection position of the detection sliding window when the cumulative sum of the similarity values is greater than a preset threshold; and generating a combined sliding window according to the recorded detection position, and obtaining a suspected plagiarism fragment according to the combined sliding window. The invention can achieve detection and judgment of a plurality of suspected plagiarism segments, and improves the detection efficiency of video plagiarism. In addition, the invention further provides a video plagiarism detection device based on the sliding window, equipment and a medium.
Description
technical field [0001] The present invention relates to the technical field of video detection, in particular to a sliding window-based video plagiarism detection method, device, equipment and medium. Background technique [0002] With the emergence of a large number of online videos, the phenomenon of video plagiarism is becoming more and more serious, and it has become an urgent problem to be solved. Video plagiarism detection is mainly used in video companies to protect their own copyrighted videos from plagiarism by others, such as TV stations and film companies. Other application scenarios also include finding unhealthy videos on the Internet, such as pornographic videos. Due to the large number of online videos and the slow speed of manual review, it will become an inevitable trend in the future to hand over video plagiarism detection to computer equipment for processing. [0003] However, the existing video plagiarism methods can usually only search for one plagiari...
