Unbelievable. My head is hurting from trying to imagine the concept behind the algorithm to do this. The desert and sky recreations are especially mind boggling.
How is something like this actually developed?
The current patch tool in Photoshop can already adjust contrast and hue to make a patch source match the patched area, so when the algorithm is searching for similar areas to use as a source it can just focus on the image details and not the lightness or actual colours.
