Image Processing of 2-Dimensional Barcode
Toshihiko Wakahara, Noriyasu Yamamoto · 2011
QR (Quick Response) codes are frequently used with progress of the Internet and introducing the QR decoding function in the cellular phone. A bar code shows an individual identification number (ID) by this number fundamentally. As the amount of information encoded by one-dimensional bar codes is limited, two-dimensional bar codes have been developed. This paper presents the dotted picture or image multiplexing method over the QR coding and the evaluation of the redundancy characteristics of the QR coding. Then, the animation method of image QR code is presented. The prototype of the QR Editor for making the QR code with the dotted pictures or image has been developed and the dotted pictures reading characteristics are confirmed by the cellular phone barcode reader.
