Representative features of the last network layer before the stationary velocity field is formed, in response to evolving MRI contrasts from the same subject. Left: VoxelMorph using normalized mutual information (NMI) exhibits high variability of the same feature response across different input contrasts for the same brain, e.g. in the red box. Right: contrast-invariant SynthMorph (sm-brains). For this analysis, both networks use the same architecture with n= 64 filters per layer.
