Crop Calculation Code

[kahnchana]

Congratulations on the really interesting work!

I am looking at the dataset preparation stage and trying to locate the code that performs the exact motion crops.
That is, for step 3 (Extract motion vectors and save as .npy files), could you point to the exact code I can use to perform this?
Or is there some simple external library like mv-extractor I should use for this?

Thanks a lot in advance!
