undoing improper resizing of interlaced video

[JClement]

I have a video of a movie that was resized from 720x480 to720x536. The original, which I never had, was obviously properly telecined 3:2. So I want to restore the original frames, then detelecine to then do a proper restoration.

So, my question is whether there are deconvolution algorithms for undoing an improper vertical resize. I would need the deconvolutions for the common resizing algorithms as I do not know which one was used.

The undo would involve a variety of trials as there may have been some cropping. One would think the resize would have been to 540 as the person who did this apparently wanted to produce a proper 4:3 aspect ratio and didn't understand that there is embedded metadata to do that by the player.
