Roundness

[Arvand Navabi]

Dear sir/madam
I wanted to get informed of the formula that Imagej uses to determine the roundness or sphericity of an area.
And how can i officially determine the formula? I need to mention the formula in my thesis.
Thank you very much

From the tutorial:

*Roundness* 4 × [*Area*]*π* × [*Major* *axis*]2 or the inverse of *Aspect
Ratio*. Uses the heading *Round*.
