| 摘 要： | 提出了一种基于倒谱域的数字水印算法,该算法将水印图像信号嵌入到宿主图像的一维倒谱系数中,水印检测不需要原始图像.计算机仿真结果表明该算法满足水印的不可感知性的要求,且可抵抗多种水印攻击,如JPEG压缩、噪声干扰、滤波以及其他图像处理操作等.试验采用了Stirmark4.0水印基准测试软件,保证了试验的真实性和准确性.

| Abstract: | A digital image watermarking method based on cepstrum domain is proposed.The sequence of watermarking is embedded into the host image in its 1-dimensional cepstrum domain. The embedded watermark can be detected without the original image. Extensive computer simulation results show that the proposed algorithm is robust to a few kinds of watermarking attacks,such as JPEG compression,additive noise,filtering and some other image processing operations. Stirmark4.0 watermark benchmark testing software is applied... |
