| 摘 要： | Contourlet变换是一种基于图像的几何性变换,通过各向异性实现了图像的多尺度多方向性分解,它能够有效地表示图像中的轮廓和纹理。利用这些特性,提出了基于Contourlet域的盲水印算法。实验证明,该算法很好地协调了透明性与鲁棒性;并且实现了盲检测。

| Abstract: | Contourlet transform is one of the multiscale and multidirection analysis methods,which can efficiently represent contours and textures in images.Blind watermarking algorithm based on Contourlet Transform is proposed.The watermark can be extracted from the watermarked image without the original image.Experimental results show the proposed algorithm has good transparency and is very robust to common image processing and geometric attacks. |
