It is the points on the moving image that are transformed onto the fixed image. Perhaps its an issue of terminology. Are you sure you need the inverse ?<br><br>One can get the approximate the EBS inverse by reversing the source and target landmarks.<br>
<br>There isn't a straightforward way to invert the BSpline. Take a look at itk::InverseDeformationFieldImageFitler . It samples the grid using a kernel transform and approximates the inverse via one of the 5 kernel transforms.<br>

Hi all,<br>
<br>
I'm transforming an image using an elasticbodysplinekerneltransform,<br>
followed by a bsplinedeformabletransform. I've got a set of points<br>
defined on the moving image that I would like to transform as well.<br>
Looking at the code (and the behaviour when I try to GetInverse()), it<br>
seems that the inverse is not implemented (or my transform is not<br>
invertible).<br>
<br>
How can I transform my point set so that it matches the transformed<br>
moving image? Thanks,<br>
<br>
Charlotte<br>
