The same pics for the damage ==> http://drop.io/rlv072i (Second one)

I mean if I can detect the color of the surface ( in RGB) and have the it changes to the color to the other surface, in the other side. and the region should be the thickness. I wanna be able to say this damage happends in 2-2.3 mm of the sample, something like that. But I am not sure how to do that.

I don't know what I am looking at in the second image, but it appears to
be non-uniformly illuminated, with the illumination strongest at the
left and weakest at the right -- the shadows are much sharper at the
left. If you do not have uniform illumination then unless you can figure
out how to correct for that problem then you are not going to be able to
do a meaningful data analysis.

Yes, it turns out this is the same image he was asking about in a
different post. I also mentioned there that the image was a mess and
that he should get a good image to start with. He outlined two
different areas in the mess that he wanted automatically found, but it
wasn't clear how a program could automatically decide where those
boundaries should be. It's such a mess that I'm not really going to
take time to tackle it - it would just take too much time.

That's right Imageanalyst, because it's the same project, I needed help with. All what I need is a simple code, that I can give it input of a specific color, (in RGB) and it will show a figure of the color dilates to white, or to another color I pick. If you can help, it would appreciated. Thanks

But it doesn't look that simple. I don't think simple code can give
you what you want.
