Left: Sequential Generation. The image is generated patch-by-patch. Right: Upscaling GAN conditioned on neighborhood information. Given border patches B1, B2 and B3, and the down-scaled version of the 4th patch, the generator generates the 4th fake patch. The discriminator also receives the border patches, as well as either an original or fake patch from the generator. The principle is similar in 3D, with the difference that 7 border cubes are used instead of 3 border patches
