摘要 本文提出了一种基于矢量量化的数字水印算法,它同时实现了图像认证和版权保护;首先应用Arnold变换将待嵌入的鲁棒水印信息和半脆弱水印信息加密,然后应用矢量量化技术将鲁棒水印和半脆弱水印分别嵌入到恰当的DWT系数中,并可以盲提取。实验结果表明,该算法同时具有较好的鲁棒性和脆弱性。 In this paper,we propose a multipurpose digital watermarking method based on vector quantization,which can be applied to image authentication and copyright protection. First,the original robust watermark and the original semi-fragile watermark are encrypted using Arnold transform,and then the original cover image is transferred by DWT. Second,we embedded the encrypted watermarks to the selected DWT coefficients,and it is a blindly embedded algorithm. The experimental results show that the proposed algorithm...
