This script helps fix noise found in digital camera pictures.

Important:

G'MIC must be installed! When this script calls up the G'MIC plug-in, select Bilateral Filter with default settings.

There seems to be some confusion as to what all this script does...  read more »

The G'MIC plug-in for GIMP defines a set of various filters, including artistic filters, image denoising and enhancement, 3D renderers, etc..  read more »

A Windows 32 version of noise-generator-0.2.5, another great plugin by Marcor.
Without console window (compiled with LDFLAGS=-mwindows).

DustCleaner is a GIMP plug-in to automatically detect and remove the dust spots in digital images. It was registered under the menu of filter->noise.
Up-to-date version can be found here (SVN):

Enjoy~ :-)

This filter generates noise in an image. Available noise types are

• Poisson noise
• Gaussian noise
• Uniform noise
• Laplace noise
• Lorentz noise

It is possible to generate (YCbCr) luminance noise only and to apply a gamma correction.

This script adds a realistic film grain effect to a black and white or toned image. To install, copy the attached file to GIMP/share/gimp/2.0/scripts. The larger the file you are running it on, the larger the value you should have for Strength. The value for Sharpness depends on your preferences, but I usually start at 1 and go from there. The lower the value, the sharper the noise.

The wavelet denoise plugin is a tool to reduce noise in each channel of an image separately. The default colour space to do denoising is YCbCr which has the advantage that chroma noise can be reduced without affecting image details. Denoising in CIELAB (L*a*b*) or RGB is available as an option. The user interface allows colour mode and preview channel selection. The denoising threshold can be set for each colour channel independently.  read more »

This is a series of scripts that implement various layer effects:

• Drop Shadow
• Inner Shadow
• Outer Glow
• Inner Glow
• Bevel and Emboss
• Satin
• Color Overlay
• Gradient Overlay
• Pattern Overlay
• Stroke

Some effects can have contours (a.k.a. curves) and noise added to them. Effects can either be applied on a separate layer, or be merged into the active layer (which in some cases gives better results).

Tested with GIMP 2.4.2.

Updated 6/9/2009:

• Stroke now supports gradients and patterns! (Python version only)
• Better undo handling in the Python version.
• Various bugfixes.

Updated 11/15/2008:

• The Python version now has live previewing! With the "Preview" checkbox active, the preview now updates automatically every time you change a setting!
• New "Reapply Effects" function: Reapplies all effects that have been applied to the current layer. If you change anything on the layer, use this to update all the effects in one go! (Mind you, this only works for effects that were not applied using the "Merge with layer" option.)
• Various bugfixes.

Updated 09/02/2008:

• Bugfix in Script-Fu version.

Updated 07/19/2008:

• You can now scale patterns in pattern overlays. (Python version only.)

Implements an ISO noise reduction as described in the tutorial below, also this script uses different methods (masking the edges and then blurring the individual color channels or the luminance channel only)

PS - Using a plugin like Wavelet denoise from http://registry.gimp.org/node/4235/ or greycstoration from http://www.greyc.ensicaen.fr/~dtschump/greycstoration/ might actually give you better results and more options for fine tuning.
