This repository is for Real Image Denoising with Feature Attention (RIDNet) introduced in the following paper
Saeed Anwar, [Nick Barnes], "Real Image Denoising with Feature Attention", ICCV (Oral), 2019
The model is built in PyTorch 0.4.0, PyTorch 0.4.1 and tested on Ubuntu 14.04/16.04 environment (Python3.6, CUDA9.0, cuDNN5.1).
Deep convolutional neural networks perform better on images containing spatially invariant noise (synthetic noise); however, their performance is limited on real-noisy photographs and requires multiple stage network modeling. To advance the practicability of denoising algorithms, this paper proposes a novel single-stage blind real image denoising network (RIDNet) by employing a modular architecture. We use a residual on the residual structure to ease the flow of low-frequency information and apply feature attention to exploit the channel dependencies. Furthermore, the evaluation in terms of quantitative metrics and visual quality on three synthetic and four real noisy datasets against 19 state-of-the-art algorithms demonstrate the superiority of our RIDNet.
The architecture of the proposed network. Different green colors of the conv layers denote different dilations while the smaller
size of the conv layer means the kernel is 1x1. The second row shows the architecture of each EAM.

-
Cd to '/TestCode/code', run the following scripts.
You can use the following script to test the algorithm
#RIDNET CUDA_VISIBLE_DEVICES=0 python main.py --data_test MyImage --noise_g 1 --model RIDNET --n_feats 64 --pre_train ../experiment/ridnet.pt --test_only --save_results --save 'RIDNET_RNI15' --testpath ../LR/LRBI/ --testset RNI15
All the results for RIDNET can be downloaded from GoogleDrive from SSID, RNI15 and DnD. The size of the results is 65MB

A real noisy example from DND dataset for comparison of our method against the state-of-the-art algorithms.
Comparison on more samples from DnD. The sharpness of the edges on the objects and textures restored by our method is the best.
Few more examples from SSID dataset.
