There's an excellent program designed with exactly this sort of problem in
mind for the Amiga called MicroMeasure. The Amiga is ideal 'cos of its easy
access to Genlocking. Essentially you connect a video camera to the computer
via a Genlock and see the image on the screen. You calibrate a distance over
which you move the mouse and can then use it for interactive measurement.
This can all be done in real time, so by sticking the video camera onto a
suitable microscope, and assuming you have something a bit faster moving
than a fungus, you can measure velocities and so forth. It also allows
measurement of areas, etc., etc.

It's not PD, but, as I remember, it's not too expensive. I also can't
remember who developed it (though I know it was done in a University in
England). I suggest contacting Commodore in the UK, or failing that, I
can probably dig out some information at home.
