About 20 years ago I wrote software to produce a sequential list of points around the perimeter object.
Part Part Syst Charact 12 ((1995) 28-37
 It was used to calculate fractal dimension, far better than box counting,  and a basis for  a very efficient way of obtaining the maximum feret diameter.

It be a very useful addition to imageJ

Subject: Output boundary coordinates of particles

Hello,
I have a problem on particle analysis using ImageJ. I need to output the boundary coordinates of discrete particles (no overlap) on a 2D 8 or 16 bit gray scale image. The output format of boundaries needs to be clockwise or counterclockwise along the perimeter of each particle. I need the particle boundary output to construct a model for finite element modeling. Does any one know how to do that in ImageJ?
Many thanks,Xinding
