[about]

GREYCstoration  is an  image regularization algorithm that processes a
color image by  removing small  local variations of  pixel intensities
while preserving significant global image features,  such as edges and
corners.  The most direct application of image regularization is image
denoising.  By extension, it can also be used to inpaint or resize im-
ages.

GREYCstoration is based on  state-of-the-art  image processing methods
using  nonlinear  multi-valued  diffusion PDEs  (Partial  Differential
Equations).  This approach generally  outperforms the  basic filtering
techniques (convolution, median filtering, etc.) used by typical image
processing programs.

Some proprietary programs use comparable denoising techniques (for in-
stance, Noise Ninja and Neat Image). However, as of 2007, the programs
in question aren't  open-source,  and the algorithms are  secret.  The
GREYCstoration source code is  freely available  (it's distributed un-
der the CeCILL License,  which is compatible with GPL).  Additionally,
GREYCstoration has two advantages over some of the competing PDE-based
regularization approaches:  It's fast, and it's able to preserve small
details (since it works at a sub-pixel level).

[technotes]

1. This package builds the Gimp-plugin version of GREYCstoration. Pre-
sently, it doesn't build the standalone CLI version.

The plugin has been  abandoned upstream and will probably stop working
at some point/

#---------------------------------------------------------------------

2. To access  this version of GREYCstoration,  load a true-color image
into  "gimp" and  execute the following operation  (starting  from the
image window):

      Filters -> Enhance -> GREYCstoration
