[Insight-users] Registration performance / sparce data

[itk@stmoser.ch]

Hi all,

Is there an efficient way of registering sparce 3D data (itkPointSet)
into a 3D fixed image (type itkImage)? I figured that I might use a
PointSet representation for a small but relevant subset of a 3D image.
Both Images and PointSets are DataObject and in principle it should be
possible to work on the data sets using interators (just as the metrics
do, as I suppose).

Thanks, Stephan
