摘要
数字水印是数字产品保护的一种新技术,近年来已在国内外引起了广泛的关注。在结合K-L变换和SVD分解的基础上,利用图像信号自身特性,提出了一种多功能水印嵌入算法,仿真实验结果表明,该方法具有较好的透明性与鲁棒性,尤其在抗图像几何操作、有损压缩方面表现出良好的稳健性。
Digital watermarking is deemed as an novel technique for copyright of digital products protecting and has aroused extensive interests in recent years. Based on the properties of the K-L transform and the SVD(singular value decomposition), this paper proposes a novel multifunction watermarking algorithm , the experimental results show that the watermarking algorithm has good transparency and robust , especially against the geometrical operations and JPEG lossy compression .
