README

This is the official Pytorch implementation of "Lung Segmentation from Chest X-rays using Variational Data Imputation", Raghavendra Selvan et al. 2020

What is this repository for?

• Predict lung masks from CXRs
• Model is trained to predict on PA/AP views
• Train the models described in the paper
• v1.0

How do I get set up?

• Basic Pytorch dependency
• Tested on Pytorch 1.3, Python 3.6
• Predict using the pretrained model: python predict.py --data DATA_DIR --model saved_models/lungVAE.pt
• Download preprocessed CXR data from here
• Train the model from scratch: python train.py --data DATA_DIR

Using preprocessed diffused masks

• For speed up, the diffused noise masks are precomputed
• 200 sample masks are provided in this file
• Check the dataloader to create more or to compute the masks on the fly
• It is recommended to use precomputed masks

Usage guidelines

• Kindly cite our publication if you use any part of the code
