Hey guys,

I usuallyu perform the following sequence on my images:
     Adjust threshold
     Despeckle
     Analyze Particles

I was hoping to learn a bit more about what goes on under the hood in these
processes.  In particular, how does the automatic threshold choose it's
region on the histogram?  Is Despeckle the common name for this method, and
what exactly does it compute?  Same for Analyze Particles.  Are these
methods unique to ImageJ, or are they based on some generally accepted
methods in image analysis.  If so, what other names to they go by? I'm
hoping to get a better sense of where this fits in to the bigger picture of
image analysis, so any context is quite helpful.

Thank you
