>>2288763By photograph you mean real people? Well that is the genius thing about neural networks. They learn to generalize. So, in the case of ecchiapp, it actually learns to identify bra/panties and try to redraw them as "nude".
So, it actually works on real images as well. Ofcourse it looks off, because it has never ever seen a real human before in training data. But the fact that it is able to identify and change the image is quite interesting. I included a couple of examples in this image.
