Questions about extracting the optical flow features.

[coding-rachal]

Thanks a lot for your great work! I am wondering how u get the optical flow features. I think it is a little confusing. I want to evaluate the method on another dataset. I tried to extract optical flow through RAFT, followed by the pretrained Resnet18 to get of features from the optical flow images. However, the predicted head pose doesn't move obviously. So, I think I extract the features in a wrong way. May I know the details about how to get the of features?
