[Insight-users] Deformable registration using Multilevel B-Spline

[wenjia]

Dear Ni Dong,

As far as I know, ITK provides the BSplineDeformableTransform class and 
MultiResolutionImageRegistrationMethod class. If you combine them together, you 
can get the multiresolution B-spline deformable registration. You can refer to 
page 377 in ItkSoftwareGuide.pdf for details. However, I am not sure whether 
this is the multi-level B-spline method that you need.

Best wishes,
Wenjia

Dear all,

My goal is to deformably register two volumes based on two sets of already 
correlated landmarks. These landmarks are irregularly localized in the volume. 
Multilelvel B-Splines algorithm by Lee(" Scattered Data Interpolation with 
Multilevel B-Splines") can get a smooth interpolation for scattered data. I have 
searched the ITK files and examples. But I just can find basic B-spline 
interpolation or transform, which commonly need the regular control point.

Do you have any idea about the implementation of multilevel B-Splines? Thank you 
very much.
