A Framework for Joint Affine and Diffeomorphic Image Registration

Anatomical image registration commonly relies on a sequential pipeline where an affine alignment is estimated first and then held fixed while a non-rigid diffeomorphic deformation is applied. This two-step process often leads to suboptimal results, as the initial stage can absorb local deformations, biasing the residua...

A Varifold-Based Score for Decoupling Deformations in Shape Analysis

A novel coupling score designed to decouple distinct deformation modes during registration is introduced, which quantifies the extent to which the action of a given vector field on a shape can be replicated by another subspace of vector fields.
