In Pix2Pix by Isola et al. they translate images from different pairs of image categories to one another. While most other example applications for the algorithm make sense to me, I'm having difficulties understanding why one would translate facade labels to facade images. As the title says, I already don't see how labeling a facade would help solving any real world problem.
I skimmed the related work of the paper and found little about what "facade parsing" could be used for, except maybe reconstruction from images. Where are facades reconstructed from facade labels? Can anyone tell me other example applications for facade labels and translating them to images?
