Detailed Description

template<typename TDisplacementField>
class itk::VariationalRegistrationDiffusionRegularizer< TDisplacementField >

This class performs diffusive regularization of a vector field.

This class implements the diffusive regularization as described in Fischer and Modersitzki. "Fast diffusion registration." Contemporary Mathematics 313 (2002): 117-128..

We efficiently compute $u^{out}=(Id - A)^{-1}[u^{in}]$ with $A[u]=\alpha\Delta u$ using additive operator splitting (AOS). Please note that $\alpha$ corresponds to $\tau\alpha$ in Eq.(2) in VariationalRegistrationFilter.

Note
This class was developed with funding from the German Research Foundation (DFG: EH 224/3-1 and HA 235/9-1).
