Hi,could you explain how to get the ground-truth noise level sigmas(yi) ,as stated in your paper.
Thanks you very much!

In the paper, for synthetic noise level, we have two noise level, \sigma_s and \sigma_c. For the clean raw image L, the image level is \sigma_c + \sigma_s*L.

Hello，could you tell me how to get the ground-truth noise level for ordinary gaussian noise which variance is sigma_g ? Thanks.
