Classification: CPC G | IPC G

Claim 14:
15. A computer-implemented system, comprising:
at least two processors; and
one or more computer memory devices interoperably coupled with the at least two processors and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the at least two processors, perform one or more operations comprising:
obtaining a plurality of feature vectors of a target video;
retrieving a candidate video similar to the target video from a video database based on the plurality of feature vectors of the target video;
constructing a time domain similarity matrix feature map between the target video and the candidate video based on the target video and the candidate video; and
using the time domain similarity matrix feature map as an input into a deep learning detection model, to output a video segment matching the target video in the candidate video and a corresponding similarity, wherein
the deep learning detection model is obtained through training based on time domain similarity matrix feature maps of a plurality of groups of sample videos and corresponding labels, a sample video comprising a query video and a candidate video corresponding to the query video, and a corresponding label corresponding to the sample video comprises a video segment matching the query video in the sample video in a corresponding candidate video and an infringement flag.
