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 。
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.
