Video Swin Transformer

Liu, Ze, Ning, Jia, Cao, Yue et al.

Understand

The vision community is witnessing a modeling shift from CNNs to Transformers, where pure Transformer architectures have attained top accuracy on the major video recognition benchmarks.

  • These video models are all built on Transformer layers that globally connect patches across the spatial and temporal dimensions.
  • In this paper, we instead advocate an inductive bias of locality in video Transformers, which leads to a better speed-accuracy trade-off compared to previous approaches which compute self-attention globally even with spatial-temporal factorization.
  • The locality of the proposed video architecture is realized by adapting the Swin Transformer designed for the image domain, while continuing to leverage the power of pre-trained image models.
