How to find max/min diameter through object's center?
As shown in the attached image, I have an irregular-shaped object. I'd like to automatically calculate:
- The maximum diameter (the longest distance across the object passing through its geometric center, labeled "CPT5" in the image).
- The minimum diameter (the shortest distance across the object passing through its geometric center).
My questions are:
- Are there any existing algorithms or established methods to achieve this automatically?
- Are there any tools or libraries that can easily implement this functionality?

Yes, these measurements are available in Image-Pro, they are called Diameter Min and Diameter Max:

Hi YuriG,
Thank you for your response! I see that Image-Pro provides the Diameter Min and Diameter Max measurements. That’s great!
However, I would also like to visualize these diameter lines on the image itself. Is there a way to automatically display them as overlay annotations? If not, is there a way to extract the coordinates of these diameters so that I can manually draw them?
I appreciate your help!
Best regards,

There is no direct way to visualize Diameters. You can display "Longest Line" or equivalent ellipse by activating corresponded count option:
Also, if you want detailed report of diameters at 1 degree step, you can add Diameters measure with 180 number of angles and see it in the Object window or Data Table:
