| 摘 要： | 提出了一种基于人类视觉系统模型的双正交小波多分辨图像水印算法,该算法充分利用小波多分辨的优点及人眼视觉系统的特性,保证了水印的不可见性及鲁棒性,同时在检测水印时也不需要原始图像,仅需涉及到相关的几个细节子图。实验表明该水印算法对于中值滤波、叠加加性噪声、JPEG有损压缩三种图像处理都是鲁棒的。检测算法还有计算量小,检测速度快的特点。

| Abstract: | A new wavelet multi-resolution watermarking algorithm for images based on human visual model is presented. This scheme makes good use of the advantage of wavelet multi-resolution and the feature of human visual system, thus keeping the watermarks invisible and robust. Also, this algorithm need not original image and is only relevant to some detail sub-images during detection. The experimental results have shown that the digital watermarks, which are inserted in host image by the proposed algorithm, is robust for median filtering, salt-and-pepper noise and JPEG compression. |
