First of all you have to come up with some idea how the "background" can
be distinguished from what you would regard as signal. Only after you have
characterized that you can proceed to choose from the variety of filters/
imaging processing techniques the most suitable ones. I would recommend
you have a look at some basic image processing textbook to get an idea of
what is possible and what isn't. A lot of different filters are already
availabe in plain IDL (see List_of_Routines_by_Application->Array_and_
Image_Processing_Routines) or can easily be implemented using IDL.

Hope this helps,

Christian
