Train

main_train_###.py

The file main_train_DRNet_###.py contains the best model in the paper:

For Gaussian denoising on gray images: main_train_NHNet.py
For Gaussian denoising on color images : main_train_NHNet_color.py
For real noise: main_train_NHNet_sidd.py

Other files, such as main_train_NHNet_no_bn.py, corresponds to the control model used in the ablation experiment.

Testing

main_test_###.py

For Gaussian noise, we provide pre-trained models of three noise level, 15, 25 and 50. Please ensure the test noise level is consistent with the model you select (you can select them in the test file). Names of the pre-trained models as follows:

---_gray15 ---_gray25 ---_gray50 ---_color15 ---_color25 ---_color50

For real noise, we provide the pre-trained model "real.pth". Test results can be produced by running file as follows:

---_sidd_valu.py for Validation data from SIDD

sidd_Submit.py for branchmark data from SIDD. The file generated by it should be submitted to http://130.63.97.225/sidd/dataset.php to receive the result report.

test_denoising_dnd.py for DND. The file generated by it also should be submitted.
