How to know the crack area on the segmented 3d image?

Hi,
I have some segmented 3d images for certain particles.
Here is one example,
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/549903/image.jpeg)
You can find some holes on the surface (circled in red) that make the hollow region inside particle connect to the outside. I am struggled to find the surface area of those holes. I have tried to use ’imclose’ to fill the hollow region and subtract to its original one and get hollow region structure. But it is not helpful for finding just the surface area of circled region.
Could anyone have some ideas?Thanks!

That is not a segmented image, at least it's not segmented for the things you care about - which are the cracks. I don't even know what you want. There are tons of little indentations and concavities all over that shape. Somehow you need to isolate just the ones you are interested in. The method you suggested should work reasonably well if you choose the right structuring element. If it doesn't, you might have to somehow manually hand-trace the regions.
