How to get videoNonLocalFlowF and videoNonLocalFlowB? #45

Thanks for sharing your impressive work! I was trying to find the non-local flow computation, but how to get these parameters of videoNonLocalFlowF and videoNonLocalFlowB in get_flowNN.py? Could you please give me some guidance for these parameters?

Hi,

Currently, I disable the usage of the non-local flow for a faster speed. But I do provide the non-local implementation in get_flowNN.py so it should be easy to use.

Basically, for each frame, you need to compute the flow to the first, middle, and last frame. And then, you can pass them to get_flowNN. Let me know if this helps.

Do I also need to go through flow completion?

Hey guys,

Really sorry for the late reply. Now the code supports non-local flow. You can enable the --Nonlocal flag.

Please note that I haven't thoroughly tested the correctness of the non-local flow (this codebase is different from the one I used for ECCV).

Hope this helps. Please let me know if there is anything I can help with.
