中文摘要: 提出了一种将彩色水印图像嵌入到宿主彩色图像的自适应水印算法. 该算法首先将宿主彩色图像分解为R、G、B三个分量并进行8*8分块DCT, 再将彩色水印图像R、G、B各分量的能量值对应嵌入到宿主彩色图像R、G、B各通道中. 实验结果表明, 该算法具有较好的不可见性和鲁棒性.
Abstract:In this paper, we proposed an adaptive image watermarking by embedding a color watermarking image into a host color image. We divide the R, G, B channel carries on 8*8 blocks separately and makes DCT for the host color image, then insert the value of each component’ energy to three channels. The experimental results show that this algorithm has the good invisibility and robustness.
