Well sometimes I might want to read them later. But If you build an 
application using the ImageViewer class, you can also do the following:

say viewer is a ImageViewer, then you can access the seed points like this:

   SeedPicker *seedpick = viewer->GetSeedPicker();
   vector<SeedPicker::Index> ind;
   seedpick->getSeedPoints(ind);

Have a look at SeedPicker.h for a definition of the Index struct.
