摘要
本文提出了一个基于纠错编码的图像水印算法,在嵌入水印时先将水印信息进行纠错编码再嵌入到图像中,在提取水印时对恢复出的水印信息进行纠错解码.实验结果表明,该算法比未采用纠错编码的同一水印算法具有更好的稳健性能.
An image watermark algorithm based on coding for error correction is proposed in this paper. The watermarks are coded for error correction before they are embedded into host image; the watermarks are decoded for error correction after they are distilled. Experimental results demonstrate that robustness of the proposed algorithm is superior to the identical algorithm that doesn't adopt error control.
