<br>Hi Prateep,<br><br>Not really, the underlying structure of the <br>BSplineDeformableTransform assumes<br>that you have a rectangular domain <br>(at least topologically).<br><br><br>You could however approximate a circular <br>
domain with the ITK KernelTransforms:<br><a href="http://www.itk.org/Doxygen310/html/classitk_1_1KernelTransform.html">http://www.itk.org/Doxygen310/html/classitk_1_1KernelTransform.html</a><br><br>if you carefully place the landmarks in a<br>
radial configuration.<br><br>You may want to try with the TPS Transform:<br><a href="http://www.itk.org/Doxygen310/html/classitk_1_1ThinPlateSplineKernelTransform.html">http://www.itk.org/Doxygen310/html/classitk_1_1ThinPlateSplineKernelTransform.html</a><br>
<br>for example.<br><br><br> Luis<br><br><br><br>--------------------------<br><div class="gmail_quote">On Thu, May 24, 2012 at 3:32 PM, Prateep Mukherjee <span dir="ltr"><<a href="mailto:pmukherj@umail.iu.edu" target="_blank">pmukherj@umail.iu.edu</a>></span> wrote:<br>

<br>
Is there a way to apply itk::BSplineDeformableTransform on circular<br>
regions ?<br>
<br>
I am currently using BSplineDeformableTransform as the<br>
transformation matrix. I couldn't find a way of setting a circular<br>
region of interest in BSplineDeformableTransform.<br>
<br>
So after placing the grid points, I need the transformation to be<br>
applied on a circular region around the grid point.<br>
<br>
Thanks a lot for your time.<br>
