I have not seen this explicitly stated anywhere so I was curious. Say I have network trained to meet my segmentation needs using 250x250 images. After this training is complete and I wish to submit images in production for segmentation, do those production submitted images need to be 250x250 as well or can they be any reasonable size?
If they must be resized to 250x250 for segmentation, is it possible to scale up the segmentation regions to apply to a larger image? If so what is the name of that technique so I can research it a bit more.
