[Insight-users] Serious problem with BSpline Registration

[Dr. Tim Allman]

I am trying to do 2D BSpline based registrations but with little 
success. It appears that there is a problem inside ITK which is 
demonstrated by the ITKWikiExample 
"Registration/ImageRegistrationMethodBSpline.cxx". I get the same 
results when I compile on Linux and OSX, 32 or 64 bits. The default 
Superbuild exhibits the same behaviour.

The first thing I noticed is that the example does not give the result 
presented on the web page 
http://www.itk.org/Wiki/ITK/Examples/Registration/ImageRegistrationMethodBSpline. 
Further, small adjustments to the optimizer parameters make wild changes 
to the appearance of the image.

If the tests are run, the following results:

The following tests FAILED:
       1 - CheckPagesForImages (Failed)
     171 - Registration-ImageRegistrationMethodBSpline (Failed)
     235 - Statistics-KdTreeBasedKMeansClustering_1D (SEGFAULT)
     236 - Statistics-KdTreeBasedKMeansClustering_3D (SEGFAULT)
Errors while running CTest

Any help in this would be much appreciated.
