Hello all,

My problem should be relatively simple to solve, but was not able to find it
or to find a solution on the forum. I have a coating that was cut and
polished and prepared in cross-section. What i want to do is to measure the
roughness of that coating using ImageJ in this cross-section image. Any
thoughts on how this could be done?

I tried to use the wand tool to define the outer part of the coating with
success but then i need to take out the x,y values of only the wand
selection cutter part. With this i might try to do a linear interpolation
and afterwards measure the roughness. But i was not able to take out the
coordinates of the wand selection.

Any other thoughts?

Thank all
