For more than a few images, such an interactive process can be
extremely tedious and inefficient.  The peiHalfTone program totally
AUTOMATES the descreening and for dozens, or hundreds, of images
this can be the difference between success and despair.

Another totally automated method for removing halftones and moire
from images is the NOTCH script for ImageMagick by Fred Weinhaus:

NOTCH uses FFT and can process color images at any bit depth
(the GMIC fft routines only process a single image channel).

I already use GMIC scripting, in conjunction with NETPBM and 
Little CMS, to automate the conversion of digital raw images
into a final form.

But the source code for the GIMP plug-in seems to be missing
or inaccessible.  I'd like to examine the Ferguson scripts
to see exactly what is done.

The latest gimp-git _can_ be installed alongside a gimp-2.8.x
installation.  Before compiling, environmental variables have
to be set that point to the gimp-get tree.  The dev versions
of BABL and GEGL have to be compiled as well.  Instructions
are found here:
