[Insight-users] Generate a pixel-wise difference image of two RGB images

[Kiet T]

Hello there,

I was just wondering how would I go about computing the difference between 
two RGB images much the same way the "AbsoluteValueDifferenceImageFilter" 
works for non-rgb images. Or is there a way to use that filter thatI don't 
know of?

Thanks,
Kiet.
