contouring the CT slice [message #34921]

Hi All,
I have serial cross sections of some long bones, which I would like to
calculate centroids and mass moments of inertia for each slice.
The steps I have managed to do so far:
1.) Read the stack as a three dimensional volume:
2.) Calculate a threshold for segmenting the data
3.) Get the internal and external contours with contours function.

The problem, when I look at the values of PATH_XY with PATH_DATA_COORDS
option, those are combined points of two contours. So sorting them out
becomes quite tricky.
The reason I need those points, I have somebody else's fortran routine
to calculate moments based on individual points and it needs two
separate inputs...

So the first question what else I can use other than contour procedure
to get the coordinates of external and internal contours? And what may
be a better way to approach this problem?
Thanks for your time,
Murat
