about feature extraction of THUMOS14

[menghuaa]

Excuse me, what methuod do you use to extract the feature of thumos14? Is it I3D?

[Pilhyeon]

Yes, we used the two-stream I3D networks pre-trained on Kinetics-400, as stated in the paper.

ok，thank you.You said in your paper that you take 16 frames of video as a segment, and then extract features. But when I output the shape (nxdimension) of the feature, n is not equal to the total number of frames /16. Why is this?

[Pilhyeon]

It is probably because we set the fps of all videos in THUMOS'14 to 25 before extracting the features.

Yes，that makes sense！Thank you very much！
