提出了一种基于视觉注意模型的数字图像水印算法,充分利用人眼的视觉注意特性,通过对图像中视觉注意区域嵌入较弱的水印信息,降低水印图像的视觉失真,对非视觉注意区域嵌入较强的水印信息,提高水印检测的鲁棒性.在多幅图像上的实验结果表明,该方法能够有效地隐藏图像水印信息,获得较佳的图像视觉效果;并且,在各种常见的图像攻击下,水印检测结果优于基于边缘的方法.

A digital image watermarking algorithm based on visual attention model was proposed by taking advantage of visual attention characteristics of human eyes, which embedded weak watermark in visual attentive part of image to minimize image distortion and strong watermark in visual inattentive part to enhance the robustness of watermark detection. Experimental results on multiple images show that the proposed approach can effectively hide watermark and obtain better image visual effects; Furthermore, the proposed method achieves better performance on watermark detection than that of methods based on edge detection under a variety of common image attacks.
