Stationary Velocity Fields on Matrix Groups for Deformable Image Registration
Johannes Bostelmann, Ole Gildemeister, Jan Lellmann
The stationary velocity field (SVF) approach allows to build parametrizations of invertible deformation fields, which is often a desirable property in image registration. Its expre…
