Nvidia Creates AI That Can Significantly Reduce Noise and Erase Watermarks From Photos

Nvidia recently demonstrated an impressive AI that uses machine learning to "map corrupted observations to clean signals... [sometimes] without ever observing clean ones." The AI is impressively powerful and can do many things, from reducing noise to removing watermarks.

Most examples of these methods involve training a neural network using good and bad versions of an image. What makes this technique so impressive is that in certain circumstances, it doesn't need good examples to train itself. The idea is an expansion of the concept of deviation-minimizing estimators, or M-estimators, which tell you how to estimate true data from a set of unreliable data. By expanding this idea to the training of a neural network, the researchers were able to obviate the need for clean training examples, creating an AI that can, for example, learn how to reduce noise in a photograph by looking only at noisy photographs. While there are of course specific mathematical caveats, it's a significant thing, as many applications often do not have clean examples to draw from, such as astrophotography. The scary part is that the AI can erase watermarks with ease, as you can see in the video above. Nevertheless, if the technology eventually reaches the consumer level, it could be a real boon for photographers when it comes to post-processing.

Damn, if this is true, it's amazing. Impressive. Damn god and Jesus almighty, how can this be real?

I'll believe it when its in photoshop.

Knowing nVidia, you'll probably need to sign an NDA and give them access to your secret photo folders.

The new NVIDIA app will be called VooDoo ....

I'm wondering if your comment was referencing Nvidia's ancient history...

Mid-December 2000, Nvidia acquired 3dfx, the company that pioneered 3D graphics processing units and cards. 3dfx was most famous for two products, Voodoo Graphics PCI (1996) and Voodoo2 (1998).

Yeah, I used to play a few games. Still have my first Nvidia GeForce 256 graphics card (released in October 1999).

Yes Nvidea, it really is.

I tried to install the app along with pyton but I cannot start the job. Maybe my fault.

Oh boy.... 250,000 ISO and flashlights...... rock n roll

Would be cool if it works. I recognize that woman with the red hat from the beginning of the video as a stock photo from the late 90s, early 2000s though.
