A typical value ofτwe studied is16—this refreshing speed is roughly 2 frames sampled persecond for 30-fps videos.
At what frequency is the data sampled for Slow pathway
-
his method has been a foundation of manycompetitive results in the literature [12,13,55].
Reference to v1b. This method does not use separate preprocessing in form of Optical Flow calculation as the network presented in v1b.
-
One path-way is designed to capture semantic information that can begiven by images or a few sparse frames, and it operates atlowframe rates andslowrefreshing speed. In contrast, theother pathway is responsible for capturing rapidly changingmotion, by operating atfastrefreshing speed and high tem-poral resolution. Despite its high temporal rate, this pathwayis made verylightweight,e.g.,∼20% of total computation.This is because this pathway is designed to have fewer chan-nels and weaker ability to process spatial information, whilesuch information can be provided by the first pathway in aless redundant manner.
Difference between pathways and computational complexity as % of total.
-
a Slow pathway, operating at low framerate, to capture spatial semantics, and (ii) a Fast path-way, operating at high frame rate, to capture motion atfine temporal resolution.
Motivation.
