Hello!

I am trying to use Fiji to find the radius of curvature of an image. I opened the image in Fiji and used the multi-point tool and selected the area that I want to find the radius of curvature of. That then generated a chart of all the multi-points with their x and y location. From that chart, there is an option to run a macro with these data points. Would someone be willing to write a macro that could calculate radius of curvature from these points? I will attach pictures below for further detail. Thank you!
