Abstract

The embodiment of the invention discloses a video duplicate checking method and device, and the method comprises the steps: constructing a multi-modal feature vector of a to-be-processed video; carrying out neighbor retrieval in a video library based on the multi-modal feature vector, screening out candidate videos similar to the to-be-processed video, and obtianing a candidate video set; calculating the similarity between each candidate video and the to-be-processed video to obtain a similarity result; and determining whether the to-be-processed video passes duplicate checking detection or not according to the similarity result. According to the scheme, the video duplicate checking efficiency can be improved while the video duplicate checking accuracy is ensured.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a video plagiarism checking method and device. Background technique [0002] With the development of online video platforms, the number of short videos and small videos has increased sharply, and users often recommend repeated videos. Duplicate videos not only disturb users, but also cause users to feel disgusted. At the same time, they waste the cloud storage of the platform, and also cause duplication and waste of platform review manpower. [0003] At present, the weight judgment is generally carried out by comparing the video to be judged with the videos in the video database one by one. However, the amount of calculations in the one-by-one comparison method gradually increases with the size of the video library, and the short video library is usually on the order of hundreds of millions, resulting in low efficiency in weight judgment. Contents of the in...
