Incorporating a measure of local scale in voxel-based 3-D image registration.

Incorporating a measure of local scale in voxel-based 3-D image registration.

We present a new class of approaches for rigid-body registration and their evaluation in studying multiple sclerosis (MS) via multiprotocol magnetic resonance imaging (MRI). Three pairs of rigid-body registration algorithms were implemented, using cross-correlation and mutual information (MI), opera...
