GIMP plugin to reduce noise in each channel of an image separately
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 Lab* 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.
The plugin can be found under “Filters > Enhance > Wavelet denoise”
