ActivityNet I3D features #35

Closed xlliu7 closed 2 years ago

xlliu7 commented 2 years ago

Thanks for sharing the code of the .awesome work. I have questions about the I3D features on ActivityNet. Are the features from CMCS or extracted on your own? I found that their features from CMCS are incomplete. The features of around 400 videos on the validation set are missing, which might affect the performance evaluation.
Thanks!

Hi, Thank you for your interest in our project. The features are from CMCS repo.

For ActivityNet dataset, the problem is that they only release the youtube-id. Some videos are no longer accessible on Youtube. Thus it is hard to achieve absolute fair comparison on ActivityNet v1.3 dataset. Also, some method re-extracted their features using different settings with I3D. I think you may want to refer to the TSP features for a fair comparison.
