Abstract
A synthetically generated noise image is generated from at least one high signal-to-noise ratio target image and at least two zero-mean Gaussian noise images, scaled according to a noise scale. The images are combined in a non-linear manner to produce the synthetically generated noise image which can be used as a training image in a machine learning-based system that 'denoises' images. The process can be repeated for a number of different noise scales to produce a set of training images. In one embodiment, the synthetically generated noise image Iis generated according to:=√{square root over ()}where I is the original target image, I=I+pGand I=pG, and where Gand Gare zero-mean Gaussian noise images, and p is the noise scale.
