TLDR
CBDNet as discussed by the authors proposes to train a convolutional blind denoising network with more realistic noise model and real-world clean image pairs to improve the generalization ability of deep CNN denoisers.Abstract:
While deep convolutional neural networks (CNNs) have achieved impressive success in image denoising with additive white Gaussian noise (AWGN), their performance remains limited on real-world noisy photographs. The main reason is that their learned models are easy to overfit on the simplified AWGN model which deviates severely from the complicated real-world noise model. In order to improve the generalization ability of deep CNN denoisers, we suggest training a convolutional blind denoising network (CBDNet) with more realistic noise model and real-world noisy-clean image pairs. On the one hand, both signal-dependent noise and in-camera signal processing pipeline is considered to synthesize realistic noisy images. On the other hand, real-world noisy photographs and their nearly noise-free counterparts are also included to train our CBDNet. To further provide an interactive strategy to rectify denoising result conveniently, a noise estimation subnetwork with asymmetric learning to suppress under-estimation of noise level is embedded into CBDNet. Extensive experimental results on three datasets of real-world noisy pho- tographs clearly demonstrate the superior performance of CBDNet over state-of-the-arts in terms of quantitative met- rics and visual quality.

Noise2Void - Learning Denoising From Single Noisy Images
TL;DR: Noise2Void is introduced, a training scheme that allows us to train directly on the body of data to be denoised and can therefore be applied when other methods cannot, and compares favorably to training-free denoising methods.
