[ITK] Call a class inside a template class

[Constantinus Spanakis]

Hello. I want to call a GaussianImageFilter inside the template class
NormalizedMutualInformation in order to study the spatial information
of the image during the image registration process. However, in order
to study the spatial information the object constructed upon the
GaussianImageFilter must have access in the image data. How can i set
the input of the filter?


PS: I know that the GaussianImageFilter has the SetInput( )  method,
but i don't know what argument I should insert.
