Abstract
In the recent year, QR code has become widely popular and has been used in various
applications. With the rapid advances in mobile communication technologies, QR code
in the embedded camera devices has been used as new input interfaces. However, the
previous works for extracting QR code from an image do not consider a non-uniform background. In this thesis, we implement the applications of QR code and propose an efficient algorithm to extract QR code from the non-uniform background. Our QR-code extraction algorithmis based on the features of QR code so that it is efficient and finds QR code position precisely. In contrast with prior works, our approach is of higher accuracy for QR-code recognition and realistic in a mobile information environment.
