hi, which model do you use to generate the optical flow? i can find several models in origin RAFT repo.

We used raft-things to generate the optical flow.

Hello, I would like to ask, 10 consecutive frames of video should output 9 optical flow. How do you achieve 10 consecutive frames of video to output 10 optical flow?

@qian507 You can try to calculate the forward optical flow and the backward optical flow, replacing the last frame with the backward optical flow.

I understand. Thank you very much for your timely response！
