Library for reading QR Codes using a Webcam

Question

I am looking for an open-source library that can read QR Codes using a laptop's integrated webcam.

Preferably, the library should be written in C#, but Java would be good as well. It should be able to run on a Windows 7 64-bit platform.

It is important that I have access to the decoded string, i.e. I don't want an application that opens up a URL in a browser. I have looked around and found libraries which either read the codes from image files, or use the webcam for input but do not allow access to the string. I haven't managed to find one which does quite what I want. Any pointers would be appreciated.

Thank you for your help and suggestions.

Answer 1

ZXing / Zebra Crossing is the software library behind the most popular QR-reading Android app called Barcode Scanner.

The core library is licensed under the Apache License 2.0 and it's robust for low-quality inputs (such as a webcam) and gives you the decoded content and lets you decide how to use it.

This will most certainly help you out.
