NVIDIA AI agent restores noisy and grainy photos (ideo)

Posted on Tuesday, July 10 2018 @ 13:54:29 CEST by


Researchers from NVIDIA, Aalto University, and MIT created a new deep learning system that can fix noise and artifacts from photos. Full details at NVIDIA. The GPU maker explains the new method is unique because it learns how to restore photos without ever observing clean ones.
Recent deep learning work in the field has focused on training a neural network to restore images by showing example pairs of noisy and clean images. The AI then learns how to make up the difference. This method differs because it only requires two input images with the noise or grain. Without ever being shown what a noise-free image looks like, this AI can remove artifacts, noise, grain, and automatically enhance your photos.

“It is possible to learn to restore signals without ever observing clean ones, at performance sometimes exceeding training using clean exemplars,” the researchers stated in their paper.“[The neural network] is on par with state-of-the-art methods that make use of clean examples — using precisely the same training methodology, and often without appreciable drawbacks in training time or performance.”
