This repository is an PyTorch implementation of the paper Recorrupted-to-Recorrupted: Unsupervised Deep Learning for Image Denoising. The network we adopted is DnCNN and our implementation is based on DnCNN-PyTorch. We give the author credit for the implementation of DnCNN.

Table 1. Quantitative comparison, in PSNR(dB)/SSIM, of different methods for AWGN removal on BSD68. The compared methods are categorized according to the type of training samples.

Table 2. Quantitative comparison, in PSNR(dB)/SSIM, of different non-learning and unsupervised methods for denoising real-world images from SIDD.
