  Hello,

I am trying to identify the diameter of a circle in an image. The backgroundmay change but the circle object will remain black or any other solid color. I needto calculate the diameter of the circle in the picture attached. Is there an IMAGEJplugin.  Else any pointer to steps/algorithm would be much appreciated!!Thanks,Vdoous
