Hi Miri,
you want to pass a 2D image to a function that expects a 3D image. This will
not work.
You can use e.g. the itk::TileImageFilter to create a 3D image from the 2D
one, so you can pass it to the function.
To use the TileImageFilter you will have to create an itk::FixedArray with
the values (1, 1, 0), and then to call tileImageFilter->SetInputImage(0,
your2DImage).
Best,
Miklos
