[vtkusers] Using vtkPCAAnalysisFilter

[sha1 at doc.ic.ac.uk]

Dear friends,
   I have been using vtkPCAAnalysisFilter for some time now. My  
problem is I am computing PCA for hundreds of images/models every time  
and it takes a lot of time. I am sure many of you have come across  
this situation. If we can calculate PCA only once ,and next time just  
restore eigen vectors and eigen values then it does help a lot in  
terms of time. If any body has such a solution/suggestion to be used  
with vtkPCAAnalysisFilter then it would be a great help. Thanks in  
anticipation.

Regards,

Hassan
