Grand Theft Auto V and through the power of magic make it look so damn
real.
This is a project by Stephan R. Richter, Hassan Abu AlHaija and Vladlen Koltun at Cornell University, culminating in a paper called
Enhancing Photorealism Enhancement. Both the paper and the accompanying video get pretty heavy on technical details, so here’s the basic summary of what they’re doing:
We present an approach to enhancing the realism of synthetic images. The images are enhanced by a convolutional network that leverages intermediate representations produced by conventional rendering pipelines. The network is trained via a novel adversarial objective, which provides strong supervision at multiple perceptual levels. We analyse scene layout distributions in commonly used datasets and find that they differ in important ways. We hypothesize that this is one of the causes of strong artifacts that can be
