This is a new and unpublished researched project I have been working on, therefore I cannot disclose too much. It is basically improving medical image registration with the help of spectral features. We have been working on the abdomen and liver which have been particularly challenging targets for registration.
I have been using python, numpy, scipy and some other libraries of python for my implementations in this project. We have also currently moved to using a deep learning framework to be used in this context, and I have been using TensorFlow or Keras to implement it.
