[ITK-users] [ITK] FEM based deformable registration

[Matt McCormick]

Hi Tony,

By default the FEM-based deformable registration assumes uniform
material properties.  If different material properties are chosen a
priori, a manually constructed FEMObject could in principle be set
with SetInputFEMObject [1].  This is much simpler than the general
inverse problem, where an attempt is made to also learn the material
elasticity.  However, if there is some indication with intensity, for
example, of local elasticity in the input images, it could be used to
generate a more realistic result.

Hope this helps,
Matt
