I'm in unfamiliar territory here but I think it can be done with NIH-Image.
NIH-Image is public domain and only runs on a Mac but you can read the 
output with a PC and it will take PC TIFF files.

I think the principle is to use the find edges command and then count or
something.  The program comes with macros for particle counting etc.
It might be worth pulling the software by anonymous ftp and just trying
it on someones Mac.  You will probably need the manual.

To ftp:


Directory:  /pub/nih-image/

Files:  nih-image154_fpu.hqx

Not promising anything ...
