Furthermore, our approach exhibits significantly faster registration speed compared to conventional iterative methods ($0. 096$ sec.

We demonstrated the added-value of our approach on the multi-coil brain MRI dataset, from the fastmri challenge, in comparison to the baseline E2E-VarNet with and without inference-time dropout.

The NPBDREG shows a better correlation of the predicted uncertainty with out-of-distribution data ($r>0. 95$ vs. $r<0. 5$) as well as a 7. 3%improvement in the registration accuracy (Dice score, $0. 74$ vs. $0. 69$, $p \ll 0. 01$), and 18% improvement in registration smoothness (percentage of folds in the deformation field, 0. 014 vs. 0. 017, $p \ll 0. 01$).

We demonstrated the added-value of our Basyesian unsupervised DL-based registration framework on the MNIST and brain MRI (MGH10) datasets in comparison to the VoxelMorph unsupervised DL-based image registration framework.

We firstly decompose a textured image into two layers corresponding to its texture and structure, and show that the layer representing the stochastic texture is characterized by random phase of uniform distribution, unlike the phase of the structured information which is coherent.
