| 摘 要： | 为了提高数字水印的实用性,必须保证水印的鲁棒性和透明性,为此充分考虑人类视觉系统特性,提出了一种基于多小波的数字水印优化方法。该方法利用Sa4多小波基进行数字水印嵌入,引入多目标优化手段对其嵌入深度进行优化调整,得到最佳嵌入效果。通过遗传算法实现的结果表明,该算法不仅对水印的攻击具有强鲁棒性,且能兼顾载体图像的质量。

| Abstract: | In order to enhance the practicality of digital watermarking,watermark perceptibility and robustness must be ensured.Taking human visual system characteristics into account fully,a digital watermarking multi-objective optimization method is proposed.It utilizes Sa4 multi-wavelet to embed digital watermark,and uses multi-objective optimization method based on genetic algorithm to optimize and adjust the embedded depth to obtain optimal effect.Experiments show the new algorithm we proposed not only is robust ... |
