| 摘 要： | 提出了一种基于DWT域的图像数字水印算法。通过对宿主图像、经过Arnold变换加密后的水印图像分别进行多分辨率小波分解,达到自适应嵌入水印信息的目的。实验结果表明,该方法嵌入的数字水印不但具有较好的不可见性,而且对图像处理有较好的鲁棒性。

| Abstract: | A algorithm with image digital watermarking based on DWT is proposed.The multi-resolution wavelet de-composition of both the host image and the watermark image which is transformed and encrypted by arnold for the self adapting embedding process is finished.The experimental results demonstrate that the embedded watermarking is invisible and has good ro-bustness against image processing. |
