<div>Hi Abayiz,<div><br></div><div> You can use the itk::TransformToDisplacementFieldSource to create a</div><div>displacement field from a rigid transformation and use the displacement as </div><div>and initial displacement for Demons. </div>

What I am trying to do is: first perform rigid registration, then use the registration result as initial displacement field for Demons registration algorithm.</div><div>But the problem is, initial displacement for Demons algorithm should be a vector field type.
