| 摘 要： | 利用图像小波分解系数的树结构关系及人眼对图像边缘区、平滑区、纹理区敏感程度的不同,提出了基于人眼视觉特性的小波域数字水印算法.选择高频子带的纹理区进行水印信号嵌入.实验结果表明,使用该算法嵌入的水印具有很好的隐蔽性,且嵌入水印的图像对有损压缩、滤波、噪声和剪切等攻击操作具有较强的鲁棒性.

| Abstract: | Useing the tree structure relation of wavelet coefficients and according to the different sensitivity of human visual system on edge,smooth region and texture of the image,a wavelet watermarking algorithm based on human visual system is proposed.The watermarking is embedded into the texture of the high frequemcy wavelet coefficient.Experimental results demonstrate that the proposed method is of robust against JPEG compression,image processing and attack such as filtering and noise. |

| Keywords: | digital watermarking wavelet transform human visual system(HVS) |
