Google has unveiled a new AI program that can denoise and reconstruct images in the dark. The RawNeRF is able to combine images taken from many different camera viewpoints to jointly denoise the scene. It works in tandem with Google’s Neural Radiance Fields, known as NeRF, a view synthesis that creates 3D renderings of a scene from multiple photos. The software is fed a collection of five to 200 photos of the same scene, which is easily shot in seconds using today’s camera technology. From the data, the AI software can manipulate focus, exposure, and tone mapping after the fact. It can even take advantage of the linear color values to render synthetic defocus with accurate bokeh effects,” Ben Mildenhall says. . . .
