Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] figure 1 The flowchart of the first embodiment of the video fingerprint-based fast video detection method of the present invention is shown. See figure 1 , the following is a detailed description of each implementation step of the video detection method of this embodiment.

[0035] Step S10: Decoding the input video to obtain YUV components.

[0036] Step S11: Dimensionalize the Y component of the kth frame after video conversion to obtain an N×M matrix, where the dimension of each frame is N×M.

[0037] The value range of k is from 0 to the last frame, the value range of N is 1-width (width), and M is 1-height (width), for example, N is 4 and M is 2.

[0038] Step S12: Calculate the centroid gradient direction of the matrix for each block in the matrix, and obtain the 3D fingerprint vector of the kth frame.

[0039] The meaning of the matri...

Abstract

The invention discloses a fast video detection method and device based on video fingerprints, which can identify the consistency between simply edited video and a homogenous video, thereby automatically controlling an infringing video which is repeatedly uploaded by a user, and reducing labor cost. The technical scheme provides the method which comprises the following steps of decoding an input video to obtain YUV (luma and chroma) components; performing dimension division for the Y components of the kth frame after the video is converted, obtaining an N*M array, wherein the dimension of each frame is N*M; calculating a center-of-mass gradient direction of the array for each block in the array, and obtaining a three-dimensional fingerprint vector of the kth frame; obtaining a fingerprint sequence according to the calculated three-dimensional fingerprint vector of the kth frame; matching the fingerprint sequence with a pre-extracted standard sequence vector of an object video, and identifying whether the input video and the target video are homogenous.

Description

technical field [0001] The invention relates to a method for detecting whether videos are of the same source, in particular to a method and a device for detecting whether videos are of the same source based on video files. Background technique [0002] With the rapid development of information networks, the number of users of online video services has also become very large. Providers of online video services have provided users with a variety of service models. Among them, user upload service (UGC), users can upload videos independently The video is uploaded to the platform of the video service provider for other users to watch, and the corresponding advertising commission can be obtained from the video service provider. Therefore, the user scale of the UGC business is very large, and the service provider also faces many difficult problems in the operation process , the most prominent problem is that the videos uploaded by users infringe the copyrights of others. Many users...
