Script to apply smart denoising to a picture, using Wavelet Denoise, Film Degrain, G'mic's Anisotropic smoothing or Patch-based smoothing, or even "L" channel blurring. Its main aim is to detect where blurring is really needed, so that to preserve most of small details.
If you use Wavelet Denoise, Film Degrain or G'mic, you need to install these plugins first.
For Wavelet denoise : http://registry.gimp.org/node/4235
For Film Degrain : http://registry.gimp.org/node/25432
For G'mic : http://gmic.sourceforge.net/gimp.shtml

After :
The 1.06 version has been replaced by the 1.07 one, which gives better results in grey and uniform colors areas.

1.08 release
In this new release, you can also use the Film Degrain plugin (http://registry.gimp.org/node/25432) which leaves a bit more noise but seems to preserve value channel better than Wavelet Denoise.
