Image Processing - Measuring geometric sizes in the image

Hello, thank you in advance for anyone who can help.

I have a grayscale image, I want to write a code that will do the following measurements:

1. Measure minimum distance in a particular area

2. Measure thickness in a particular area

see attached pdf

You can assume 1mm = 1 pixel

Are you wanting to click on the image to select the points to measure? Otherwise how do you plan to obtain the pixel data?

no. i want the code to do that for me, maybe using edge function
