Hi if i have a single pore, and i have calculated pore boundries already, and i have matrix of x and y cordinates of the pore.
How can i calcualte radius of curvature of 3 points of that pore. Thank you

Just fit a circle through the xy coordinate data and you would get centre and radius. See

Why does that matter? Obviously you can repeat the process for every set of 3 points that are of interest.

I agree with Matt. You can do permute and repeat the circle fitting process for all combinations.
