Slowfast源码讲解
WebbThe slowFastVideoClassifier object is a SlowFast video classifier pretrained on the Kinetics-400 data set with a ResNet-50 3-D convolutional neural network (CNN). You can use the pretrained video classifier to classify 400 human actions such as running, walking, and shaking hands. Webb10 dec. 2024 · We present SlowFast networks for video recognition. 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. The Fast pathway can be made very lightweight by reducing its channel capacity, yet can …
