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 w ell .
