Poisson-Gaussian noise implementation

[xlying55]

Hi, I notice that the Poisson-Gaussian noise parameter are randomly sampled. How do you determine the 0.16 and 0.06 range for sigmas? I also read the implementation in the unprocessing paper, they use a quite smaller range (lower noise level).

Hi, when setting the sigmas, we choose a large range of noise levels to handle more noise images. For unprocessing paper, they set the range of sigma by the DND dataset. Thus the setting of our paper is wider.
