Resizing Masks
I observed that after resizing, some masks that were not touching before do touch. I think that this happens on the following line:

Is that correct? There are functions to resize and prevent touching, e.g., function resize_mask from delta.imgops.
Yes it's possible that masks could touch after a resize, especially depending on how the connectivity is defined, and because I assume you're using binary masks because of DeLTA?. If you want to avoid it with a quick fix, I recommend generating data with labelled masks (which are allowed to touch) and then iterating through each mask and doing morphological erosion on them one by one, then convert to binary, and re-label, with an assertion that there are the same number of masks as before.
