[Insight-users] filter with multiple inputs

[iamrndm b]

I am trying to develop a fillter which accepts 2 images as inputs and
produces a  third image.
i am trying to find an example which does that .

i have a couple of question
the example
http://www.vtk.org/Wiki/ITK/Examples/Developer/ImageFilterMultipleInputs
is not clear to me , it appears to take just one image as input.

Secondly if we are deriving from the class ImageToImage filter. it only
accepts one image and produces the output , how does the multiple image
input then fit in .


thanks
