how to use the "Flow-Square-Mean" in Motion effects

[mamianshusheng]

I can't find the function or any other files to use Flow-Square-Mean ?

[mamianshusheng]

Did you open source this function? I can't find it in any of the files.

Hi, thanks for your attention!

We obtain the evaluation code directly from https://github.com/princeton-vl/RAFT, and we have not integrated it into eval.py. We use the square average of the predicted values from adjacent frames to represent the motion dynamics of the video.

Thank you for your reply. It's really nice of you.

@fanfanda could you please provide more specifics about how you evaluated using RAFT, so that it can be used for evaluating other video generation models? which of their models did you use? Did you compute the mean of the square of the norm of the flow (MSE)? or "the square average" = the square of the mean of the norm? Did you normalize by anything (video resolution, number of frames etc)?
