I want to digitize some index cards with my camera. I'm looking for a program that would automatically fix geometry on the shots (as you would expect the cards come tilted on the picture).

I have an app (droid scan lite) on my android phone that does exactly that, but I would prefer to do it on my pc (the phone camera has poor quality and it's slow and focuses badly while I have a decent slr). If the program is open source it's an advantage, cross platform -- even more so.

The title is a bit deceptive, but I can't think of something better. – Ignacio Vazquez-Abrams Feb 12 '11 at 7:08
There used to be a website called Qipit that would do this exact thing, but it's gone now :-( – digitxp Feb 12 '11 at 12:02

I'm using CamScanner and I find it quite useful.
