Hello @piloubazin, @juhuntenburg . I’m interested in working on this topic as a part of GSoC 2019. I’m currently pursuing a Master’s degree in Computer Science and have worked extensively on MR images and machine learning. In order to proceed working on this topic, I’ve started going through the paper mentioned above. Regarding the same, I would like to know whether there are any already preprocessed images available that I can use? If not then I would proceed with the preprocessing steps mentioned in the paper.
