| 摘 要： | 本文提出一种小波域的自适应可见水印处理算法,该算法通过特殊设计的视觉模型,根据主图像和水印图像的特征,逐点确定水印嵌入的拉伸系数,从而使水印的嵌入程度依主图像和水印图像的特征变化而变化.实验表明,结果图像中的水印半透明地呈见在所覆盖的主图像区域,很好地保持了原始图像的细节,满足了对可见水印的一般性要求.

| Abstract: | In this paper,a wavelet domain visible watermarking technique has been proposed,where the scaling factors are determined by using both host and watermark features.The pixel-based adaptive scaling of watermark image is most suitable to make the degree of marking applied variable according to both host and watermark features.The experimental results have shown that the resulting image meets the requirements of visible watermarks quite well. |

| Keywords: | image watermark visible watermark adaptively watermarking wavelet domain watermarking |
