AIUI, GEM is or includes a process that applies a sigma filter. Running such a filter over a large pixel-dimensioned image can be very process-cycle-intensive, depending on the filter dimension parameters. It does not seem surprising that it could take quite a while on a 400 mhz machine. There's a brief description of a sigma filter at www6.ewebcity.com/rayet/articles/imageprocess/imageprocess.asp -- Bob Shomler http://www.shomler.com/gallery.htm
