[Insight-users] SetFixedImage

[Luis Ibanez]

Hi Tony


Is the variable "mesh" a Mesh reader ?

Is the variable vtkMDHReader a reader that will produce an itk::Image ?

Is your registration class a ImageToImageRegistration ?


If you are doing ImageToImage registration, you
*should not* pass a Mesh as the FixedImage, because
a Mesh is not an Image.

If your image reader is a VTK image reader, that
returns a vtkImageData, then you must first convert
this image to an itkImage before passing it as
argument to the SetMovingImage method.

It seems that what you want to do is


     PointSet to Image Registration


You may want to look at

    Insight/Testing/Code/Algorithms
        itkPointSetToImageRegistrationTest_1.cxx



   Regards,


      Luis
