Seam carving removes continuous seams (wavy lines) of pixels that are hard to perceive after being removed. Thus it's well suited for changing the aspect ratio of images (in Photoshop this is called content aware scale), since if you remove a seam the image gains or loses a whole row or column of pixels. But it's less suited for filling in big holes, where you need to find the right textural pattern to put in the hole. To do this we made a new tech called "patchmatch" that basically dices the image into little squares (patches) and then matches similar patches:-). We used this core tech in a global optimization, where good matches outside the hole are pasted in the hole, averaged, and then this is repeated until convergence. I did this at an internship at Adobe.

It's the fact that the GPL gives the same result whether copyright laws exist or not that makes it such a solid foundation for software freedom (modulo minor bugs). This is not true. If copyright laws did not exist, then it would be legal to make GPL software "closed source."
As for freedom, I think a more natural definition is "doing what you want with your computer" (i.e. anarchy) than whatever bizarre concoction Stallman is cooking up nowadays. I'm sure the brainwashers and propagandists (the ideological children of Stallman) will be sure to jump on me for stating that, but consider this: what greater threat is there to freedom than brainwashing and propaganda?
