Hi,
Are you looking for an algorithm in general, or for an existing third-party component?
I don't know of a ready-made component, but I did write in the past about the concept of 2D barcode reading from still images. Unfortunately, it was in Hebrew. Fortunately, there's Google Translate... so if you're interested, try to make the most of
http://translate.google.com/translate?js=y&prev=_t&hl=iw&ie=UTF-8&layout=1&eotf=1&u=http%3A%2F%2Fnet.nana10.co.il%2FArticle%2F%3FArticleID%3D646486&sl=iw&tl=en
BTW despite what this translation says, my surname is Gendel, not Gandel, and I did not use the exact expression "my ass" in the title!
Two useful links:
