Remove watermark from image with GimpPosted: July 27, 2011
1. The quick and simple method
You can very easily heal an image stamped with watermark in GIMP. Bear in mind though that in case of the semi-transparent watermarks it is not a precise restoration of the image mathematically to its former self, indeed it is sooner “healing” of the image, as parts of it are filled with newly generated content to make it blend with the rest of the picture. Still this method is good enough for most of the everyday situations and more often than not produces really good results.
You need the Resynthesizer Gimp plug-in to do this (available also for Windows).
Install the plug-in by:
sudo apt-get install gimp-resynthesizer
- open the picture with GIMP
- select the area you want to heal (the more precise the better)
- select Filters > Map > Resynthesizer
- click Ok
- Create exact replica of the watermark as semi-transparent white on solid back
- Invert colors
- Place this image as a layer above the image you want to remove the watermark from
- In the “Layers” window set the mode of the top layer to “Burn”
