Our model involves (i) a Slow pathway, operating at low frame rate, to capture spatial semantics, and (ii) a Fast pathway, operating at high frame rate, to capture motion at fine temporal resolution. tshibaka twitterWebbSlowFast is a new 3D video classification model, aiming for best trade-off between accuracy and efficiency. It proposes two branches, fast branch and slow branch, to handle different aspects in a video. Fast branch is to capture motion dynamics by using many but small video frames. philosopher\u0027s hcWebb1 apr. 2024 · 1.
