This implementation was developed based on the repository https://github.com/eriklindernoren/Keras-GAN/tree/master/srgan.

Dependencies

• tensorflow
• keras
• numpy
• keras_contrib
• scipy==1.2
• Only GPU-based calculation is supported now.

Inference Utilization

• Step 1: Place all the noisy image (in grayscale .png format only) in a folder ($input_dir$)

• Step 2: Under the root folder of the tool, input the command:

python inference.py --input_dir $input_dir$

• Step 3: The de-noised results will be place in $input_dir$/denoised_out

• Note: Image shapes in the input folder can be arbitrary and different.

Training Utilization

• Step 1: Prepare the training set and validation set in .npy format with 0~1.0 value range. For each set, noisy input data and clean groundtruth data should be placed in noisy and clean sub-folders individually with the same file names.

• Step 2: Modify Lines #16, #23, #55, #62 in the "data_loader.py" file to specify the dataset.

• Step 3: Hyper-parameters of the training could be modified in Lines #132, #142, #147, #514 in the "pam_denoise_main.py" file.

• Step 4: Run the command python pam_denoise_main.py to start training.

• Step 5: Training results will be saved in "./saved_model".
