G'MIC is an open and full-featured framework for image processing, providing
several different user interfaces to convert/manipulate/filter/visualize
generic image datasets, from 1d scalar signals to 3d+t sequences of
multi-spectral volumetric images. Technically speaking, what it does is:

* Define a lightweight but powerful script language (the G'MIC language)
dedicated to the design of image processing operators and pipelines.

* Provide several user interfaces embedding the corresponding interpreter:
- A command-line executable gmic, to use the G'MIC framework from a shell.
In this setting, G'MIC may be seen as a serious (and friendly) competitor
of the ImageMagick or GraphicsMagick software suites.
- A gimp plug-in, to bring G'MIC capabilities to the GIMP image retouching
software. (gimp-plugin-gmic)
- A krita plug-in, to bring G'MIC capabilities to the krita digital painting
software. (krita-plugin-gmic)
- A web service G'MIC Online, to allow users applying image processing
algorithms directly in a web browser.
- A Qt-based interface ZArt, for real-time mainpulation of webcam images.
(gmic-zart)
- A C++ library libgmic, to be linked to third-party applications.
(libgmic1, gmic-devel)

G'MIC is focused on the design of possibly complex pipelines for converting,
manipulating, filtering and visualizing generic 1d/2d/3d multi-spectral image
datasets. This includes of course color images, but also more complex data as
image sequences or 3d(+t) volumetric float-valued datasets.

G'MIC is an open framework: the default language can be extended with custom
G'MIC-written commands, defining thus new available image filters or effects.
By the way, G'MIC already contains a substantial set of pre-defined image
processing algorithms and pipelines (more than 1000).

G'MIC has been designed with portability in mind and runs on different
platforms (Windows, Unix, MacOSX). It is distributed under the CeCILL license
(GPL-compatible). Since 2008, it is developed in the Image Team of the GREYC
laboratory, in Caen/France, by permanent researchers working in the field of
image processing on a daily basis.

G'MIC has superior denoising and sharpening capabilities.
