| 摘 要： | 提出了一种DWT域位平面的自适应鲁棒数字水印算法,即将水印信息根据DWT域HVS模型嵌入小波域低频逼近系数高位位平面的不同平面,有效地提高了水印信息的鲁棒性。实验结果证明该算法具有很好的鲁棒性,同时保证了水印的不可见性。

| Abstract: | This paper brings forward an adaptive robust digital watermarking method based on bit plane decomposition of the image watermarking in DWT domain.It embeds the watermarking into the different higher bit plane decomposition of approximate coefficients in DWT domain according to the HVS model.The watermarking method that the paper brings forward makes progress in robustness of watermarking.These tests prove the methods to make image distortion lower and be robust-easy to use. |
