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 ...

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 ...
