Learning to solve inverse problems using Wasserstein loss

This repository contains the code for the article "Learning to solve inverse problems using Wasserstein loss".

Contents

The code contains the following

• Training using circle phantoms

Pre-trained networks

The pre-trained networks are currently under finalization and will be released soon, in the meantime, training is just a few hours.

Dependencies

The code is currently based on the latest version of ODL and the utility library adler. They can be most easily installed by running

$ pip install https://github.com/odlgroup/odl/archive/master.zip
$ pip install https://github.com/adler-j/adler/archive/master.zip

The learning requires tensorflow, and the ray-transform needs ASTRA for computational feasibility

$ conda install -c astra-toolbox astra-toolbox
