What is the sigma image means? #22

Hello, There are imgs with prefix 'SIGMA_SRGB' in the folder 'Syn_train', and they are used as the ground truth as the FCN net. I wonder what is meaning of the 'sigma images' and how can i generate it?

It means the noise std used in noisy image generation. You can use codes in utils/syn/generate_dataset.py to generate it.
