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.

Any inputs on the actual image recognition capabilities (speed+quality) of both libraries would be helpful.

TIA.

As for me ZXing is better. I have used them both at work for iOS application.

  1. With ZBar I had problems with large QRCodes.

  2. ZXing works fine on iPhone 4 and 3GS, but Zbar works worse on 3GS, some times it just can't capture the code.

But if you need not only QR codes, you have to use ZBar.
