The G'MIC plug-in for GIMP proposes a set of various filters to apply on your images, including artistic effects, image denoising and enhancement algorithms, 3D renderers, etc.. It is a quite large plug-in, integrating a lot of different effects.

GREYCstoration was a noise reduction plug-in for GIMP, based on the technique of anisotropic diffusion partial differential equations.

GREYCstoration has been discontinued, and is now replaced by the G'MIC project, which contains all the former GREYCstoration features, but also much much much more !
