How to UniMatch to evaluate optical flow score?

[windelvin]

As for part 3: Curating OpenVid-1M, Motion Difference module, the paper says "We introduce UniMatch [27] to evaluate optical flow score as the motion difference score to select videos with smooth movement". However, UniMatch[27] is a image semantic segmentation method, how it can be used for optical flow?

Thanks for your attention. We use UniMatch [27] to evaluate optical flow score. We have fixed it and added some new content in an updated version of paper, which will be released soon.
