Entropy-regularized optimal transport

This repository contains the code for the article "Generalized Sinkhorn iterations for regularizing inverse problems using optimal mass transport" by J. Karlsson and A. Ringh. To appear in SIAM Journal on Imaging Sciences. arXiv:1612.02273.

Contents

The code contains the following

Note that the two hand images used in the article do not belong to the authors and are therefore not included.

Installing and running the code

Clone the repository and install ODL (version 0.6.0) and ASTRA (version 1.8). This can be done, e.g., by using miniconda run the following commands to set up a new environment (essentially follow the odl installation instructions)

After this, the scripts can be run using, e.g., spyder.
