title: Decoding QR Codes with Java
body: <p>I have approximately 2000 images with QR codes in them, each representing exactly one letter. Does anyone know a good open source framework in Java (Java prefered, but any other language is fine, too) to decode them? </p>
  
  <p>I have only found shareware frameworks and web services that won't allow me to upload 2000 images to their server.</p>
