Alternatively one can consider the image as a landscape and use greyscale
morphology to extract "domes" of a particular height.

The morphology plugins in my site include a "Domes_" plugin, which supports
only 8 bit greyscale. Not sure if that would be suitable for your problem,
though.

The paper to read about this approach is: Vincent L. Morphological greyscale
reconstruction in Image Analysis: Applications and efficient algorithms. IEEE
Trans Image Proc 2(2) 176-201, 1993.

I hope it helps.
