Abstract

In medical imaging, deep learning has been applied to segmentation and classification tasks successfully, whereas its use for image registration tasks is still limited. The use of discrete registration can alleviate the problems limiting the use of CNN based registration for large displacements by helping to capture more complex deformations. We evaluate different building blocks of learning based discrete registration for the CuRIOUS multimodal image registration challenge. We also propose a new attention module, which estimates information contents of a grid point, compare different loss functions and evaluate the influence of self-supervised pre-training of feature extraction step.
