A research on QR Code recognition enhancement using pre-constructed image matching scheme

Recently, as the smartphone market is growing rapidly, the amount of using QR Code with smartphone is increasing together. This paper proposes a new method for improving the rate of QR Code recognition on smartphone. In some angles, sometimes, a few applications cannot recognize QR code. So, this method make it possible to recognize the QR Code any angle. In order to find an original QR Code we proposes a method which recognizes QR code imaginary at first, then send information of this QR Code to an area of QR database. Finally we use `image matching method´ between recognition of QR Code and the database we already had.
