Gimp plugin to losslessly decompose images into wavelet scales layers
[ edited version of author’s www site ]
This plugin losslessly decomposes a layer of an image into layers of wavelet scales. This means that you can edit the image on different detail scales frequencies. The trivial recomposition of the image can be done by GIMP’s layer modes so you can see the results of your modifications instantly. Among the applications are retouching, noise reduction, and enhancing global contrast.
The plugin can be found under “Filters > Generic > Wavelet decompose”
