Denoising based on AI

Exporting/importing photos in full 32-bit representation (to train a neural network for image denoising)

Hello all, a while ago I made a dataset of clean/noisy images to train a neural network for image denoising, published under Natural Image Noise Dataset - Wikimedia Commons (there is also a paper associated, http://openaccess.thecvf.com/content_CVPRW_2019/papers/NTIRE/Brummer_Natural_Image_Noise_Dataset_CVPRW_2019_paper.pdf ) The images were processed in darktable with all the steps applied except for sharpening (which amplifies noise), and aligned with Hugin tools, and the result was rather e…

With that said I think CR2 >Grey scale .PGM > Noise reduction > pgm2dng > .DNG that I wrote before is the wrong way to go if one want to implement it into darktable
