Nvidia AI turns sketches into photorealistic landscapes in seconds
- cow9 8y agoGAN generally works very well for landscapes, which is what is being demonstrated, not so much for objects esp humans. It’s still impressive though.
- jcims 8y agoAren’t GANs behind things like thispersondoesnotexist.com?
- marrowgari 8y agoYes. But that's a network finely tuned on facial images, which is more complex than landscapes. GANs can create all types of images, it's just that landscapes happen to be the type of media currently created with the least complexity due to the more abstract nature of the details involved.

IIUC, their contribution is a masking normalization layer (the 'SPADE' layer [see pg 4]) that allows the network to preserve the structure of the input segmentation/mask, leading to results quite a bit nicer than previous ones.
- marrowgari 8y agoAll future media should be watermarked with immutable metadata linking it back to it's original source to verify authenticity and combat fake news.
- yarg 8y agoCan't we just be honest about the current state of the art and say "near photorealistic"? Unless you're half-blind you can tell there's something off about these pictures.
