WebbThe Slow pathway (Fig. 1, top row) is a convolutional network that processes videos with a large temporal stride ( i.e ., it samples one frame out of τ frames). The primary goal of Slow pathway is to produce features that capture semantic contents of the video, which has a low refreshing rate (semantics do not change all of a sudden).
