Timothy,
One source of inspiration for the focusing algorithm is to look at codes
that expand the depth of focus by stitching together the in-focus portions
of multiple images. This is used in microscopy quite a bit. The software has
to be able to identify which portions of the picture are in-focus. Here is a
link to a description of the technique: http://www.sgi.com/grafica/depth/.
One of the steps is to detect edges. ImageMagick will do that
http://www.imagemagick.org.
Good luck,
Andy
