This plugin provides a simple interface between GIMP and GNU Octave.
Means you can edit a picture from GIMP in the high level numerical language Octave:
Download elsamuko-gimp-octave.c and install it with:
$ gimptool-2.0 --install elsamuko-gimp-octave.c
You will find it then under Filters -> Mathematics -> GIMP Octave.
The input/output matrices and the Octave script are stored then in ~/.gimp-octave.
For more interesting examples, download and unzip the filter pack in ~/.gimp-octave.
The filter pack needs the octave-image package which should be available in your repository.
