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

This plug-in is able to update his list of filter definitions from the Internet (so it improves itself over time), as well as allows any user to add its own custom filters in it.
It has been written by the author of the GREYCstoration algorithm (used for image denoising). It is actually intended to replace it in a near future.

Here is one screenshot of the plug-in in action, as well as a result of filter application :

dechroma

dechroma is a simple but effective chroma noise reduction. Chroma noise appears usually in high ISO photographs. The method used in this script allows to reduce noise but does not affect details. It decomposes the picture in the LAB channels, blurs the chroma noise on the red and blue channels, and recomposes the picture. The default settings of the blur radius should be appropriate for general uses, but can be change.
