摘要 本文提出了一种新的小波域自适应可见水印算法.依据载体图像和水印图像的特征,结合人类视觉系统特性,算法逐点确定水印嵌入时的加权系数,使水印信号的嵌入根据载体和水印图像特征的变化而变化.仿真实验结果表明,水印图像半透明地呈现在所覆盖的载体图像区域,算法简便快捷. A new adaptive visible watermarking algorithm based on DWT proposed in this paper. With the characters of the human visual system,the factors are defermined by both host and watermark fea- tures adaptively. Experiments show that the watermarked image meets the requirements of visible wa- termarks quite well.
