[vtkusers] vtkPCAAnalysisFilter/vtkProcrustesAlignmentFilter and number of points

[mabou88]

Hi

I want to use vtkPCAAnalysisFilter and vtkProcrustesAlignmentFilter.
According to the documentation, I need for my vtkpolydatas to have the same
number of points before using those class. My Mesh (polydata) are
segmentations of different patients and don't have the same number of
points. I used the class vtkdecimatepro but it only reduce cell and after,
my polydata have the same number of cells, but different number of points. 

How can I achieve this? Is there an other tool to make different mesh
(polydata) with the same number of points?

Thanks 
Marc
