PyTorch DRGAN

----A Pytorch implementation of Noise-Powered Disentangled Representation for Unsupervised Speckle Reduction of Optical Coherence Tomography Images.

1. File Description

data

• train_valid: the directory to store data for training and validation.
• test: the directory to store test data.

dataset

• dataset.py: python script to build pytorch Dataset and DataLoader.

models

• base_model.py: the father class implementing the network building, setup input, forward computation, backpropagation, network saving and loading, learning rate schedulers, and visualization of losses and metrics.
• drgan_model.py: containing the forward and backward process of our proposed model.
• drgan_nets.py: the implementation of our proposed network achitectures, such as Encoder, Decoder etc.

run

• trainer.py: a basic template python file for training from scratch, or resuming training, and validation the Model.
• tester.py: a basic template python file for testing the Model.

utils

• help_functions.py: the python file can be used to store and modify the model initilization strategies and optimizer scheduler settings.
• metrics.py: the python file can be used to store and modify the evaluation metrics.
• visualizer.py: the python file can be used for visualization of the losses and images.

main.py: the script for running the code (train/validation/test).

• if you want to train the model from scratch, run

python main.py --mode train --start_epoch 1

• if you want to resume the training process, run

python main.py --mode train --start_epoch epoch_you_want_to_resume

• if you want to test the model, run

python main.py --mode test --load_epoch parameters_epoch_you_want_to_test

configs.py: the python file can be used to store and modify the hyper-parameters for training, validation and testing process.

2. Installation

• Clone this repo:

git clone https://github.com/tsmotlp/DRGAN-OCT

cd DRGAN

• Install PyTorch 1.0+ and other dependencies (e.g., Pillow, torchvision, visdom)

3. Train and test DRGAN on your own data

if you want to train and test DRGAN on your own datae, your just need to:

• prepare you own train, validation and test data into directory data.
• modify the hyper-parameters in configs.py to make it suitable for your own data.
• follow the instructions of main.py.
• To view training results and loss plots, run python -m visdom.server and click the URL http://localhost:8097.
