Slowfast timesformer
WebbWe present SlowFast networks for video recognition. Our model involves (i) a Slow pathway, operating at low frame rate, to capture spatial semantics, and (ii) ... Our method, named “TimeSformer,” adapts the standard Transformer architecture to video by enabling spatiotemporal feature learning directly from a sequence of frame-level patches. WebbMMAction2 is an open-source toolbox for video understanding based on PyTorch. It is a part of the OpenMMLab project. Action Recognition on Kinetics-400 (left) and Skeleton …

Webb3. SlowFast Networks SlowFast networks can be described as a single stream architecture that operates at two different framerates, but we use the concept of pathways to reflect analogy with the bio-logical Parvo- and Magnocellular counterparts. Our generic architecture has a Slow pathway (Sec. 3.1) and a Fast path- Webbthe SlowFast [9] and CSN [21] are based on convolution, and ViViT [1] and Timesformer [3] are based on trans-former. In fine-tuning stage, the features extracted by back-bone are …

WebbHuman visual recognition is a sparse process, where only a few salient visual cues are attended to rather than traversing every detail uniformly. However, most current vision networks follow a dense paradigm, processing every single visual unit (\\eg, pixel or patch) in a uniform manner. In this paper, we challenge this dense paradigm and present a new …
