摘要： 提出了一种基于差错控制的图像水印算法,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,该算法比未采用差错控制的同一水印算法具有更好的稳健性。

Abstract: An image watermarking algorithm based on error control is proposed in this paper. The watermarks are coded for error correction before embedding into host image, the distill watermarks are decoded for error correction. Experimental results demonstrate that the proposed algorithm is superior to the identical algorithm that doesn't adopt error control in robustness.
