QR codes are the most widely used in two-dimensional barcodes nowadays. Image pre-processing is an important process to achieve QR code image recognition in complex conditions and binarization that ...

An algorithm that exploits properties of QR codes. The study, which is part of Ismael Benito's doctoral thesis at the UB, presents a new algorithm that takes advantage of the QR's own ...

User Registration Taking user details like name, secure voter ID, age and encrypting the details using Advanced encryption standard algorithm(AES). 2. QR Code Generation Dynamically generating a ...

To solve this issue, a team from the University of Barcelona and Universitat Oberta de Catalunya has developed a new algorithm that helps read QR codes even when they are printed on non-flat or ...

QR codes are designed with alignment and scaling features, not to mention checksums and significant redundancy. They have to be, because you’re taking photos of them with your potato-camera w… ...

Pseudo-boundary would appear in the processing of local binarization, and the calculation would take long time. This paper puts forward an improved background gray-level based binarization algorithm ...
