I have this image :

As you can see It has a transparent layer of QR Code and I need to extract It somehow..

How can I do this?

I tried selecting the QR Code using color range.

enter image description here

but as you can see It was an unsuccessful attempt.

Most of a QR code isn't needed in most situations. You have almost all of the code on the left and top which holds most of the data. upload.wikimedia.org/wikipedia/commons/thumb/1/1d/… If all fails, try to at least recover the top and left area and as much of that corner of the image as possible as data is read into the code from left to right, top to bottom. Most likely, the information in the bottom right corner is error checking. –  OghmaOsiris Jan 9 at 1:20
    
How many of these do you have to do? Just one? Or a whole bunch? –  TunaMaxx Jan 9 at 21:51
    
Just this one. Anyways I did it by HAND DRAWING the QR Code! It was 5 hours of torture... –  l0oky Jan 10 at 6:36

If you go online and google "QR code generator", there are several sites that will generate a QR code for free. Type in the URL which the QR code refers to, i.e. "www.company/webpage" and tell it to create the code, and you can download the QR code as a clean vector file. Some of them will even let you specify the size of the code (1", .5", etc) and the color (black, white, etc). I think it is safest to stick with a code that is at least 3/4" in size (newer cell phones can read smaller QR, but older cell phones still need the bigger size). I would do this rather than try to painstakingly pick the code off its background....

PS I only know this because I had to set up a QR code on a brochure recently!

Thank you very much for your answer, but this isn't quite what I was looking for. This was a Photoshop question as you see the tag 'adobe-photoshop'. –  l0oky Jan 10 at 20:05
    
oh, sorry! New to Stack Exchange. did not notice tag! –  Harriet Jan 11 at 22:50
    
oh, sorry! New to Stack Exchange, did not notice Tag. (Redrawing the QR does seem like torture, thought the online code generators could help you avoid that step!) Anyway, hope your project works out well. –  Harriet Jan 11 at 22:58
    
No problem :D and thanks. –  l0oky Jan 12 at 0:34
