| 摘 要： | 提出了一种新的基于小波域的自适应鲁棒图像水印算法.算法结合临界视觉误差(JND),使得该算法在保证不可觉察下,加强了鲁棒性.该算法可以在没有原图情况下准确地检测出水印图像.对嵌水印图像作典型图像处理试验,表明该算法具有很好的鲁棒性.

| Abstract: | In this paper, an new image-adaptive watermarking technique based upon a wavelet transform is proposed The watermarking algorithm utilizing the just noticeable distortion(JND) values, the transparency of the hidden watermark can be guaranteed. It's not necessary for the original image to be available for successful detection of the watermark. The experiments with common image-processing operation on the watermarked image shows that the algorithm is quite robust. |
