[Insight-users] please urgent answer about pointset to image registration

[Luis Ibanez]

Hi Tony,

You probably instantiated the "registrationMethod" type using a
FixedPointSet different from your declaration of

   typedef itk::PointSet< float, Dimension > FixedPointSetType;

Please make sure that you declaration of the PointSet to Image
registration class looks like:

   typedef itk::PointSetToImageRegistrationMethod<
     FixedPointSetType,
     MovingImageType >    RegistrationType;

and that the Metric declaration looks like:

   typedef itk::NormalizedCorrelationPointSetToImageMetric<
     FixedPointSetType,
     MovingImageType >       MetricType;


If these two declarations are consistent with your FixedPointSet
as declared above, then you shouldn't find any problem assigning
the fixed point set with the method


     registrationMethod->SetFixedPointSet( mesh )


That is, your "mesh" object *MUST* be of type "FixedPointSet"
or *MUST* derive from this type.




If you continue experiencing any problems please do the
following:


    1) Post to the list your *full* code of these file,
       not just incomplete snippets.


    2) Post to the list the *full* and *exact* error message
       that you get from the compiler.




   Regards,



      Luis
