| 中文摘要: |
| 在前人的基础上提出了具有旋转、伸缩及平移不变性的RST不变小波算法RSTXIW,并将此算法应用于数字水印领域.实验表明,RSTXIW不变小波算法具有较小的重构误差,其伸缩误差比双线性插值好仅稍逊于双三次插值,以它为基础的水印算法对于旋转、伸缩、平移等几何攻击具有较好的鲁棒性. |
| 英文摘要: |
| Based on Dr.Xiong’s theories,this paper provides a Rotation- Scaling- and Translation- Xiong’s invariant wavelet transform,i.e.RSTXIW.We also design some experiments to test the RST-invariant performance of RSTXIW and the robustness of its application in digital watermarking.The experiments show that the reconstruction errors of RSTXIW is less,its scaling errors is less than the bilinear interpolation and whose performance is close to bicubic when scaling factor very close to 1,and its application in digital watermarking has good robustness against geometrical attacks such as,rotation,scaling,and translation etc.geometrical transformation. |
