3D-CSL: self-supervised 3D context similarity learning for Near-Duplicate Video Retrieval. (arXiv:2211.05352v1 [cs.CV])

In this paper, we introduce 3D-CSL, a compact pipeline for Near-Duplicate
Video Retrieval (NDVR), and explore a novel self-supervised learning strategy
for video similarity learning. Most previous methods only extract video spatial
features from frames separately and then design kinds of complex mechanisms to
learn the temporal correlations among frame features. However, parts of
spatiotemporal dependencies have already been lost. To address this, our 3D-CSL
extracts global spatiotemporal dependencies in videos end-to-end with a 3D
transformer and find a good …
