Direct LDDMM of Discrete Currents With Adaptive Finite Elements


We consider Large Deformation Diffeomorphic Metric Map-ping of general m-currents. After stating an optimization algorithm in the function space of admissable morph generating velocity fields, two innovative aspects in this framework are presented and numerically investigated: First, we spatially discretize the velocity field with conforming adaptive finite elements and discuss advantages of this new approach. Second, we directly compute the temporal evolution of discrete m-current attributes.
