Many times, after patching your pictures in GIMP you need to make some blur in order to let the picture appear “more natural” and less tainted.

This is accomplished in Photoshop with the Median Filter. In GIMP there is no filter named ‘median’, however the same effect can be achieved by the despeckle filter : Filters > Enhance > Despeckle

Øyvind Kolås’s Image Processing with gluas documentation and in Chapter 5. Area operations he mentions in a footnote:

^[5] The despeckle filter for gimp is more advanced than a simple median filter, it also allows for being adaptive doing more work in areas that need more work, it can be set to work recursivly. For normal median operation adaptive and recursive should be switched off, the black level set to -1 and the white level to 256.
