In this video, we are going to learn how to detect QRCode and BarCode in an image using OpenCV. We will first look at the basics and then move on to create an Authentication project in which we will check whether a person is authorized or unauthorized based on the QRcode on their ID.

[@maryamforouzan7403]

hello sir Thanks for all your tutorials, since they were really useful and complete. I would be thankful if you answer one of my questions please: How could we increase the resolution of the image so that the barcode would be recognized faster? Sorry that I ask because I am occupied with a project that is compiled on a tablet and the resolution of the webcam is low. Sincerely yours,

[@kirksurber7262]

Superb...

[@murtazasworkshop]

Thanks

[@Rodrigo.S.Santiago]

Hello Murtaza, is it possible to measure the rotation of the Qr code or the location of the squares ?

[@Rodrigo.S.Santiago]

It is possible using the contour detection, the onle trick is to know the relation between the Qr Code area and que corner's square area

[@carylgastardo8913]

Thankyou for sharing your knowledge sir, can you please send the source code sir for academic purpose only

[@hoomanetesamifard5995]

Hi Murtaza Would it be possible to make another toterial to show how to send the barcodes to another TCP client . Thank you

[@ezequielbecerra6992]

Is this useful for PDF417 2d Barcode?
