Sir
what you said is exactly right..But the model development of damage analysis is not my part..i'm only concerned with the extracting data from micrographs..thats my work...

So extracting the number of facets is the difficult thing and i'm trying to do that...i have to develop a code to extract such details..

Can you give any idea for counting the number of facets of damaged portion??..that will be very helpful for me..

I'm thinking that after labeling the damaged portions, using 'convexhull' or by some othr means drawing a polygon around the damage portion and later cheking out the neighboring pixels around the boundary and so on..and when a pixel encounters a neighboring pixel as part of the grain boundary we can increae the count..
I'm not sure weather my idea works or not, i have to try it.

thank you.
