Hi all..i'm new to matlab and i need some help...

I have to analyse a micrograph(is a picture showing grains, grain boundaries and defects) of steel and find the area damage in the micrograph...its an RGB image which looks like a greyscale image...i want to measure the lengh of total grain boudnaries and the area fraction of the damage...i worked out for grain boundary detection but aunable to find the area fraction of damage...

can anybody help me out..??
