The QR code is widely used since it is useful for the mobile phone with CCD camera. It is printed on surface of media for scanning. So it is thought ahead to be dirty. Even if it is dirty, we may be able to read it
since it has error correcting capability. The data stored in a QR code has been subjected to interleaving.
However, current interleaving is not enough to scatter. In terms of error correction, we have proposed a method of erasure error correction on QR code decoding.
In this paper, we show that current interleaving leads resistance to errors to be weak and reform method of erasure error correction we have proposed. Our new method enables us to do more accurate erasure error correction. |
