Filter image with moving window and averaging pixels [message #52350]

Hello,
I need to filter some noise out of an image and was pointed towards
making a moving/sliding window (size, say 7x7) and compare the center
pixel with surrounding pixels right next to border (ignoring middle
pixels). And compare the value of center pixel with the border average
pixels and thus filter out noise. However, I am not sure how to do
this.
Anyone has any idea?
Did I say I was new to IDL...?
Thanks for all your help,
my last query was met by very helpful replies, and I am grateful!
