BTW: All of the techniques David descriped are discussed in the "IMAGE
Processing in IDL" book included in your IDL distribution; IMHO the
most useful user guide of all of them.

It's likely you will need some sort of pre-image processing.
Erosion/Dilation, smoothing, unsharp masking, etc. are all
possibilities. It depends on the image and this is the art
of the process, rather than the science. :-)
