一种带纠错功能的鲁棒数字图像水印算法

提出一种基于水印数据纠错置换的数字图像水印嵌入方案.通过对二值水印图像进行置换,引入纠错机制,并将其应用于传统的小波域算法中.实验结果表明,在相同的水印嵌入强度和攻击强度条件下,通过引入纠错机制,可以显著提高水印在抗JPEG压缩、抗剪切、抗缩放、抗中值滤波、抗噪声干扰等方面的鲁棒性.

A ROBUST DIGITAL WATERMARKING ALGORITHM WITH ERROR CORRECTING

This paper proposed a digital image watermarking embedded scheme based on the permutation of watermark data to correct error.We introduce an error correcting scheme by permuting binary watermarking image,and applied it to the traditional DWT-based watermarking algorithm.We tested the algorithm performance in terms of different attacks,such as JPEG compression,image cropping and resizing,median filter,and noise interference.Experimental results show great improvement on the watermark robustness after this er...
