A problem of image denoising, when images are corrupted by a non-stationary noise, is considered in this paper. Since, practice, no priori information on noise available, statistics should be pre-estimated prior to denoising. In paper, deep convolutional neural network (CNN) based method for estimation map local, patch-wise, standard deviations (so-called <italic xmlns:mml="http://www.w3.org/19...
