A methodology to read QR codes on uneven surfaces
Sometimes, we try to capture a QR code with a good digital camera on a smartphone, but the reading eventually fails. This usually happens when the QR code itself is of poor image quality, or if it has been printed on surfaces that are not flat -- deformed or with irregularities of unknown pattern -- such as the wrapping of a courier package or a tray of prepared food. Now, a team has designed a methodology that facilitates the recognition of QR codes in these physical environments where reading is more complicated.
