摘要
为了提高数字水印技术的鲁棒性和改善嵌入水印信息的视觉特征,提出了一种采用图像融合的水印算法。该水印算法嵌入的水印信息采用作者的肖像,在水印的嵌入和提取过程中采用小波变换和图像融合技术。实验结果表明该水印算法具有以下优点:水印直观;有较好的抗噪声、抗压缩鲁棒性;算法简单。
In order to improve the robust virtue of digital watermarking and the visual character of embedded watermark information, a robust watermarking algorithm using image fusion is proposed. Author＇ s portrait is used as embedded watermark information. Technologies of wavelet transform, image enhancement, and image fusion are involved in the watermark embedded and extraction processes. Experimental results show that this watermarking algorithm has many advantages, such as characteristic watermark information, better anti-noise and anti-compression robustness, and simple algorithm.
