【摘要】 该文提出了一种基于DCT变换域的数字水印算法,主要思想是利用密钥分散将原始二值水印图像经Arnold置乱加密后嵌入到原始图像中,并通过Matlab实现了该算法。实验结果表明,该算法具有良好的不可感知性和鲁棒性,能有效抵抗裁剪、噪声等攻击。更多还原

【Abstract】 In this paper,a DCT-based watermarking algorithm was proposed.The watermarking was embedded in the original image by Arnold scrambling encryption,we realize algorithm by Matlab.After experiment,the results show that algorithm have a good perception and robustness,it can stick up to the attack just as cut、noise and so on.更多还原
