[ITK-users] [ITK] Combining two images after registration

[Andrew Harris]

Thanks for getting back to me,
I looked at that filter and it has a warning that said “No numeric overflow
checking is performed in this filter”, so I assumed that meant that if I
put an image through it there would be a simple addition pixelwise across
the image.  That would make the overlap region brighter than the
non-overlap region which I was trying to avoid.
