AI can now fix your grainy photographs without a "clean" reference

Good news for amateur photographers everywhere: You might still be able to salvage all those grainy pics taking up space on your hard drive. On July 9, researchers from NVIDIA, Aalto University, and MIT unveiled a new AI program that can effectively remove the noise from a photograph -- those annoying pixels and specks that show up when you take a pic in low light. And it doesn't even need a "clean" reference image to make it happen. The researchers plan to present their AI at the International Conference on Machine Learning in Stockholm, Sweden, this week. To create their noise-filtering AI, the researchers started by adding noise to 50,000 pairs of clean images.
