Utilize the matlab function regionprops(...,'MajorAxisLength'). This will return the diameter of a circle needed to enclose a region. You could also utilize regionprops(...,'BoundingBox') and use the maximum of the height/width as the diameter of the circle. You could then use the center of the 'BoundingBox' or 'centroid' to place the circles accurately for visualization puproses.
