Calculate maximum diameter? [message #47300]

Hi folks,

I have a set of roughly circular ROI's for which I want to compute the
maximum diameter - the longest straight line from one point on the
boundary of the ROI, through the center, to the opposing boundary. Any
ideas about the best way to do this? I do a loop I guess....compute
the diameter for all 360 degrees around the center. Principal
components analysis also springs to mind, but some of these ROI's have
different scales in the x and y dimensions. Can anyone help?

Jeff
