title: ZBar vs. zxing - QR recognition comparison
body: <p>Can anyone tell which library is better in small QR Codes recognition under low lighting conditions?
  Platform is iPhone 4/iOS 5
  I tried both Barcodes (zxing) and the ZBar apps and it seems that zxing was noticeably better in recognizing the codes under "hard" conditions. That said, it wasn't a very large sample test.</p>
  
  <p>Any inputs on the actual image recognition capabilities (speed+quality) of both libraries would be helpful.</p>
  
  <p>TIA.</p>
