Slowfast python
WebbWe select 4 frames for the slow branch (temporal_stride = 16) and 32 frames for the fast branch (temporal_stride = 2). Similarly, you can specify num_segments, new_legnth, etc. to obtain stronger features. There are many other options and other models you can choose, please check feat_extract.py for more usage information.
