| 摘 要： | 针对变换域数字水印算法中水印信息鲁棒性和不可感知性之间的矛盾，提出一种基于人类视觉系统特征的离散余弦变换(DCT)数字水印算法。对水印信息进行Arnold置乱变换，将水印信息量化嵌入到载体图像的DCT域直流分量中。实验结果表明，该算法能有效抵抗噪音干扰、裁剪和压缩编码等攻击，具有较好的鲁棒性。

| Abstract: | For the clash between robustness and invisible,this paper proposes a image watermark algorithm based on human visual characteristics of Discrete Cosine Transform(DCT) domain.In this algorithm,the watermark image to be embedded is transformed with Arnold transform,and the watermark image transformed is embedded into the host image's Direct Current(DC) block of DCT domain in which the texture is more complexity.Experimental shows that the hidden of the method is better,and it can withstand a certain amount of... |
