If you follow a few erodes by a few dilates, the end effect is the removal of tiny specs and detail on the bigger specs. example: '''''''' '''''''' '''''''' ''''''*' '''''''' '''''''' '''''*'' '''''''' '''''''' '***'*'' -> '''''''' -> ''**'''' '*****'' erode ''**'''' dilate '****''' ''**''*' '''''''' ''**'''' ''*''''' '''''''' '''''''' '''''''' '''''''' '''''''' > Reading the documentation isn't much help -- in fact the phrase "You ought to > select isolated defects before applying filter." in the help file is quite > mysterious. What does it mean? just that despeckle can damage stuff which is just fine, in a photo, so selecting areas where you're interested is a good thing.
