programs are open-source and are dependent on other open-source code.
They will run on nearly any distribution of GNU/Linux and are distributed

search for dots in an image makes use of a recursive algorithm
which collects dark pixels that are connected to other dark pixels.
Shown here are pixels being identified and marked, along with
a cross marking the "center of mass" or running average
of the dot's center. Dots which contain too few pixels are discarded
as noise. Of course, the actual calculation is thousands of times
