[Insight-users] ResampleImageFilter

[Luis Ibanez]

Hi SriValli,


You are instantiating the ResampleFilterType
using "FixedImageType", but are connecting
as input a "MovingImage".  I wonder if the
image types you used for the fixed and moving
images are equivalent.

Please post to the list the declaration of
the types

           FixedImageType
           MovingImageType


Thanks


    Luis
