This paper talked about image stabilization for bar-code scanners for mobile devices. The current problem is most mobile devices are not made to take a close up picture. They are also not very good at anti shake features either.
It address this fact and uses a few different methods to help recreate the bar-code from a blurry picture or even a picture that is taken at an angle. The process they use is first take the picture, then restore the QR code image, then convert it to a binary image, then use edge detection, then dilate the image, then create a block mapping of the image, then produce the output. They can accomplish this by the ratio of white to black in the image.
