为了提高基于数字水印技术的快速响应（QR）二维条码的水印容量和防伪性能，提出了一种二值图像灰度化算法，使变换域水印方法成为可能。在灰度化算法的基础上，设计了基于量化的离散小波域水印算法。实验结果表明，该算法在不丢失条码信息的前提下，大大提高了二维QR条码的防伪性能。
In order to increase the watermarking capacity and improve the anti-counterfeiting performance of quick response (QR) two-dimensional (2D) barcode based on digital watermarking technique, this paper proposes a kind of graying algorithm for binary image to make transform domain watermarking methods possible. Based on the graying algorithm, the quantization-based watermarking scheme in discrete wavelet transform (DWT) domain is then designed. The experiments show that the proposed watermarking scheme for QR 2D barcode greatly improves anti-counterfeiting performance without loss of any barcode information.
