Hi,
 
I have an object of interest in an image that is round but has a discontinous perimeter (cross-section through a metallic foam rod). I would like to automatically draw a ROI (circle) that best fits the outline. In user mode this is simple as one simply constrains or shrinks the ROI until it touches the metal. The result is the cross section bound by a round ROI.
 
Can anyone suggest a simple approach to code this so it does not have to be done manually ?
 
Thanks
