[Insight-users] BsplineDeformableTransform

[Reinhard Hameeteman]

Hi,

Two little questions about the BsplineDeformableTransform:

1) Why is in all the examples and in the itkSoftwareGuide the spacing
between the grid points set to an integer multiple of the voxel sizes?
I do not see a reason why the grid points should coincide with a voxel
position. If this is necessary I think it is better to directly
provide the grid spacing in number of voxels to avoid errors when
raising the number of grid points or using a smaller image.

2) A question I raised earlier due to the procedure followed in the
examples the upsample the spline grid
(http://www.itk.org/pipermail/insight-users/2007-March/021306.html):
Is the doxygen documentation of this class correct in stating: "The
parameters for this transform is N x N-D grid of spline coefficients"

Thanks in advance,
Reinhard
