The root of the problem with NikonScan is that there are ragged
edges around dust spots after applying the ICE correction using
the infrared channel.  The ICE algorithm applies a smoothing
filter over the whole image to smooth out these ragged edges
around dust spots, while VueScan only does the smoothing in
the immediate vicinity of the dust spots.

I fixed this quite a while ago.
