| 摘 要： | 提出了一种性能良好的图像水印算法，该算法在嵌入水印时先对水印信息进行奇偶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奇偶解码，实验结果表明，该算法比未采用奇偶编码的同一水印算法具有更好的不可见性和稳健性。

| Abstract: | An image watermark algorithm of good capability is proposed in this paper. The watermarks are encoded for parity before they are embedded into host image; the watermarks are decoded for parity after they are distilled. Experimental results demonstrate that robustness of the proposed algorithm is superior to the identical algorithm that doesn't adopt parity coding. |
