I do this using the Particles8 plugin on a binary image with the "morphology"
and "redirect" options. This collects shape, size and geyscale/colour
information that can then accessed from the Results Table. This is available
in the Morphology zip in my page.
Some macros there show how to delete particles, the Delete_ZeroArea uses the
flood fill of the area selected with the wand on the original image, while the
KeepParticlesInRange macro uses binary reconstruction.
Hope it helps
