%X Choosing the adequate registration and simulation
parameters in non-parametric image registration methods is
an open question. There is no agreement about which are the
optimal values (if any) for these parameters, since they depend
on the images to be registered. As a result, in the literature the
parameters involved in the registration process are arbitrarily
fixed by the authors. The present paper is intended to address this
issue. A two-step method is proposed to obtain the optimal values
of these parameters, in terms of achieving in a minimum number
of iterations the best trade-off between similarity of the images
and smoothness of the transformation. These optimal values
minimize the joint energy functional defined in a variational
framework. We focus on the specific formulation of diffusion
registration, but the exposed methodology can be directly applied
to other non-parametric registration schemes. The proposed
method is validated over different registration scenarios.
