Hi all,
Can I use compare -metric AE... expect specified color? I have relatively big images with solid background color, and want to measure differences from just like 50px thin line (other colors mostly, gray shades) and it is very hard to adjust tolerances and -fuzz percentage.
Thanks for your help.

I don't understand the question.

If you want to count the number of pixels that aren't green, you could create another image the same size, entirely green. Then compare with metric AE.
