[Insight-users] PBNRR CreateDeformedImage

[Fotis Drakopoulos]

Hi David,

The purpose of the "CreateDeformedImage" method is to warp the moving image
according an inverse deformation field  (direction:  from the deformed mesh
to the undeformed mesh).
The FEMScatteredDataPointSetToImageFilter generates a direct field
(direction: from the undeformed to the deformed mesh).
In case that you want to warp the moving image by using  the WarpImageFilter,
 you should generate an inverse  deformation field and set this field as an
input to the WarpImageFilter.

Regards,
Fotis
