Hello dear developers,
We are a group of 5 french students and we have to understand how such a program works. Indeed our teacher asked us to define the mathematical objects which are used in the quality improvement of a picture.

GIMP provides many tools for improving the quality of a picture in the form of filters, toolbox tools, extensions, procedural database (PDB) routines, etc. Normally, it requires a human to determine which tool to apply - and when. Is there anything specific you are interested in?

In particular the
process... We've already did some researchs which conducted us to the Fourier transform... And to be honnest it´s quite hard to conceptualize for us. If someone could explain us the source code and/or the maths hidden behind, simply and efficiently, we will be very grateful to him. With all our respect, we please you to agree our cordial thoughts.

Hi,

I think you find many answers to your questions in the [GEGL code], which is GIMP's backend graphics library. Some other image processing parts are in the [GIMP code]. There the directories 'modules', 'plug-ins', 'libgimp*', 'devel-docs' look like the right places for you to look at. If you have questions about the technical architecture of GIMP: one of the next points on my todo list is the software architecture documentation of GIMP. Questions are welcome, so I'll get a notion what other developers are interested in.

Kind regards,

Sven
