How is the "diameter" of an irregular shape defined? Is it the largest straight line matching into the object? Or the mean length of all lines through the center?

I think the mean cross sectional distance would be pretty close to the Equivalent Diameter which is returned from regionprops().
To find the maximum Feret diameter, see the attached demo.
