NVIDIA’s AI Tool Realistically Pastes The Visual Style Of One Photo Onto Another

NVIDIA has been pretty ambitious with its AI projects lately. Not too long ago, it introduced tools that instantly adjust photos’ angles, create wholly new faces out of celebrities’ portraits, and render eerily authentic-looking “fake” videos.
Its next task, named ‘FastPhotoStyle’, is equally impressive, and strives to realistically convert photos into seamless overlays for other images.
“Photorealistic image style transfer algorithms [aimed] at stylizing a content photo using the style of a reference photo,” the algorithm’s creators described in their research paper.
While similar tools already exist in the market, the researchers say that the results rendered from them are usually unsatisfactory; the goal of this project is that the end product must “remain photorealistic.”
To create images that are as believable as possible, the AI goes through a two-step process. The first, stylization, simply applies an aesthetic from a photo to another like you would a filter. The second blends in rough edges so that images appear “spatially consistent.”
According to one of the inventors, Ming-Yu Liu, testers were twice as partial to the AI’s renderings than manual recreations by humans. The tool also works “60 times faster” than some of the industry’s favored frameworks.
NVIDIA has released the ‘FastPhotoStyle’ code repository on GitHub. The tool runs on a Creative Commons Non-Commercial Share Alike license, so be sure to check the terms before you use it for your project.
