Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] figure 1 is a schematic structural diagram of a video deduplication device according to an embodiment of the present invention. Such as figure 1 As shown, the device may include: a decomposition module 10, which is used to divide the first video collection into a plurality of video subsets according to the text data of the videos; a calculation module 30, which is used to calculate the two video subsets in the video subset by using a space vector model. degree of similarity; the deduplication module 50 is configured to perform deduplication processing on the videos in the video subset according to the degree of similarity to obtain a second video collection.

[0032] With the present ...

Abstract

The invention discloses a video duplicate removal method and device. The video duplicate removal method includes the first step of dividing a first video set into a plurality of video subsets according to video text data, the second step of calculating the similarity of two videos in the video subsets through a spatial vector model, and the third step of carrying out duplicate removal processing on the videos in the video subsets to obtain a second video set according to the similarity. According to the video duplicate removal method and device, the problems that in the prior art, accuracy of duplicate removal conducted on the videos is low and calculation complexity is high are solved, and accurate and quick duplicate removal on massive videos can be achieved.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a video deduplication method and device. Background technique [0002] In the field of video search, it is necessary to deal with a large number of video sources from different providers, among which there are a large number of duplicate videos, especially some popular videos. This will seriously affect the quality of search and video recommendation results, resulting in a decline in user experience. So how to remove videos with the same content has become a problem that must be solved in video search. [0003] The most common video deduplication method is to deduplicate through the md5 value of the video file. This method considers files with the same md5 value to be the same video. In projects with video files, this method can identify a large number of repeated videos, but its disadvantage is that any small operation on the video file will cause a difference in the md...
