Hi everyone,

I have a like-circle shape (a closed 2D curve), and I want to find two “diameters” of it. One is the max diameter, which means the max distance between two points on the curve; the other one (min diameter) is the distance perpendicular to the max dimameter, and should be max in this direction. The attached pic shows my demands.

My idea for the max diameter is that, I segament the curve into many points, then measure the distance between any two points then get the max one. However, I don’t know how I can ge the min diameter.

Any suggestions and help are so appreciated!
