By default all augmentation operations on segmentation maps result in aliasing, because segmentation masks/labels use nearest neighbor interpolation. Any cure against it?

@ducha_aiki I faintly remember a paper that did super resolution of segmentation maps conditioned on the image, to generate edges consistent with the image Transforming & downsampling those can maybe help with aliasing
@ducha_aiki Or you can reformulate it as an alpha matting problem
@Xallt_ @ducha_aiki If it’s synthetic data, generate at higher res than necessary first.
