area of aggregated clay particles

ferrari-3
Dear all,
I am looking for a good procedure to measure area changes of aggregated clay
particles in ESEM images. I have several images of the same aggregate taken
in different times. An example image (1390KB) can be found here:

http://www.etcg.upc.es/doc/Kantha/Images/aggregate.tif

What I'd like to do is to isolate the big aggregate in the centre of the
image and to calculate its area. I tried several ways to detech clearly the
borders of the aggregate but no one of those was really good. Can anybody
help me?
Thanks,
Alessio Ferrari
