Claim 4:
5. The computer-implemented method of claim 4, wherein when there are a plurality of candidate videos, the drawing the similarity matrix between the plurality of feature vectors of the target video and a plurality of feature vectors of each of the candidate video on a two-dimensional feature map based on a time domain mapping relationship between the target video and the candidate video, to obtain the time domain similarity matrix feature map between the target video and the candidate video comprises:
drawing a similarity matrix between the plurality of feature vectors of the target video and a plurality of feature vectors of each of a plurality of candidate videos on each of a plurality of two-dimensional feature maps based on a time domain mapping relationship between the target video and the plurality of candidate videos, to obtain a plurality of time domain similarity matrix feature maps between the target video and the plurality of candidate videos; and
splicing the plurality of time domain similarity matrix feature maps between the target video and the plurality of candidate videos, to obtain a time domain similarity matrix feature map between the target video and the plurality of candidate videos.
