I’m seeking a library, technique or advice on how to read an EAN-13 barcode from an image (including ISBN,and ISSN encodings).
The image would come from a mobile phone or webcam, so resolution may be quite poor and not well aligned.
I’m specifically interested in something that could be used from ruby on rails, but answers for other languages are welcome. Open Source solutions preferred.
