Strange results in QRCode recognition

I am trying to use the product to recognize a photo with several QR images, in the most of the cases there are five o six in a A4 page. I take a photograph using a mobile phone (Galaxy Note)

Normally only three or four codes are recognized, the result looks independent of the resolution (8M, and 3.2M) , the codes have generated using different error correction level (https://developers.google.com/chart/infographics/docs/qr_codes) but there is no difference in the results.

The codes are not near so there is no confusion between them.

The url I am using is:

$url = 'http://cloud.ocrsdk.com/processImage?profile=barcodeRecognition&exportFormat=xml&correctOrientation=false&imageSource=photo';

Thanks in advance

Best Regards

Rafa

Hello Rafa,

Thank you for the images. The developer says that the issue occurs because the QR-codes are too near to the pictures, and there are too many separators around it. He recommends to put less stickers on each page.

We are sorry for the inconvenience.
