Claim 2:
3. The computer-implemented method of claim 2, wherein the 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 comprises:
constructing a similarity matrix between the plurality of feature vectors of the target video and a plurality of feature vectors of the candidate video based on a vector retrieval result between the plurality of feature vectors of the target video and a plurality of feature vectors of each of the candidate video; and
constructing the time domain similarity matrix feature map between the target video and the candidate video in a time domain dimension based on the similarity matrix between the plurality of feature vectors of the target video and the plurality of feature vectors of the candidate video.
