I have tested the latest feature (removing objects from an image) on two different images (credits to Nadine).
Removing a scratch from a girl’s skin
As you can see in the image below, this (otherwise gorgeous) friend of mine has an ugly scratch on her back:
If you select (very roughly) the scratch and ask for its removal using the resynthesizer plugin, it’s gone:
Yes, that’s it. It has been replaced by new skin automatically.
Removing a plane from the sky
I also tried it on a bigger image:
By very roughly selecting the plane, do you think it will be possible to remove it? Here is the result:
Impressive, eh? Out of curiosity, I made GIMP compute the difference between both images. Here is the result:
Yes, you can even use this plugin, after applying the right black and white threshold (1-255 is white, 0 is black), to get an alpha mask of the plane.
I hope that this plugin will be included in the next version of GIMP.
Oh, of course, GIMP and the resynthesizer plugin are both available as Free Software.
