鲁棒性是数字水印的重要指标之一,本文提出将分组码,卷积码编码的数字水印应用于数字版权保护中,利用编码纠正水印误码来降低检测误码率,提高水印受到攻击的鲁 棒性。实验结果表明,数字水印图像对具有高斯白噪声的攻击具有很强的鲁棒性。 关键词: 数字水印 纠错码 小波变化 鲁棒性 Abstract:Robustness is one of the important requirements of digital watermark. To improve the robustness of watermark,error correcting code can be applied in watermarking,intending to lower the decection error rate.The conclusions are demonstrated by the experiment results.
