| 摘要: |
| 提出了一种基于小波变换的自参照图像数字水印算法,该算法在小波域中通过对小波系数的修改得到原始图像的自参照图像,然后通过计算原始图像与参照图像的差值得到水印的嵌入位置;通过大量的仿真实验,证明该算法对常见的图像处理,如JPEG压缩、噪声以及滤波等,均具有较好的鲁棒性。 |

| Study on a self-reference digital watermark algorithm based on wavelet transform |
|
|
| Abstract: |
| This article proposes a self-reference digital watermark algorithm based on wavelet transform.The algorithm revises the original image in wavelet domain,which obtain the self-reference image,and find the embedding position through comparing the difference between the original image and the self-reference image.Plentiful emulation experiments show that the algorithm is robust to familiar image processing such as JPEG compression,noise contamination and filter etc. |
| Key words: wavelet transform digital watermarking self-reference image |
