Researchers with the University of Illinois Urbana–Champaign and Intel have developed a deep neural network that brightens ultra-low light images without adding noise and other artifacts. The network was trained using over 5,000 pairs of images, each with an under-exposed and a longer exposure version. The final result is a system that automatically brightens up images at a much higher quality than traditional processing options, which often add high levels of noise. The team used images captured with a Fujifilm X-T2 and a Sony a7S II, but also with phones like the iPhone X and the Google Pixel 2. High-resolution images can be seen here, and a PDF document of the full study can be downloaded there. Impressive!
