This AI Converts Quick Sketches to Photorealistic Landscapes

posted by Jason Kottke   Mar 27, 2019

NVIDIA has been doing lots of interesting things with deep learning algorithms lately (like AI-Generated Human Faces That Look Amazingly Real). Their most recent effort is the development and training of a program that takes rough sketches and converts them into realistic images.

A novice painter might set brush to canvas aiming to create a stunning sunset landscape — craggy, snow-covered peaks reflected in a glassy lake — only to end up with something that looks more like a multi-colored inkblot.

But a deep learning model developed by NVIDIA Research can do just the opposite: it turns rough doodles into photorealistic masterpieces with breathtaking ease. The tool leverages generative adversarial networks, or GANs, to convert segmentation maps into lifelike images.

Here’s a post I did 10 years ago that shows how far sketch-to-photo technology has come.
