[Insight-users] Inputs do not occupy the same physical space!

[Cagatay Bilgin]

Hi Francois,

You can use the region of interest filter
http://www.vtk.org/Wiki/ITK/Examples/ImageProcessing/RegionOfInterestImageFilter

or you can use the pad filter
http://www.vtk.org/Wiki/ITK/Examples/Images/ConstantPadImageFilter

to make sure that the images have same size. Is this what you are after ?
