SlowFast video recognition through dual frame-rate analysis

WebbBuild SlowFast model for video detection, SlowFast model involves a Slow pathway, operating at low frame rate, to capture spatial semantics, and a Fast pathway, operating at high frame rate, to capture motion at fine temporal resolution. WebbSlowFast 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.
