PadIfNeeded augmentation is poorly named. It crops as well as pads.

[bw4sz]

If you have an image that is larger than the padding size, it crops the image to that size. The real underlying issue is https://kornia.readthedocs.io/en/latest/augmentation.module.html#kornia.augmentation.PadTo. I think we can write our own augmentation? I think this can be marked good first issue unless @jveitchmichaelis thinks there is some complexity here.

Desired functionality

An augmentation that pads the image to a given size if it smaller than that size. If it is larger, do nothing.

Hey, can I give it a shot? @bw4sz

Hi @bw4sz,

I can take a look at this. My understanding is that we need a custom augmentation that only pads images smaller than the target size and leaves larger images unchanged, avoiding the cropping behavior in Kornia’s PadTo. Happy to propose an implementation if that sounds reasonable.

Hi everyone - thanks for your interest and contributions. I'd ask that you please carefully look over the issue before proceeding with contributions. If you do this on this issue you'll see:

which indicates that a core developer already had a WIP pull request going on this issue before anyone asked about contributing or opened a PR. In this context it is generally best to just leave the issue, but if you want to contribute you should ask the person already doing the work first if they need/want any help before proceeding.
