摘要
利用遗传算法搜索出最优的初始值和嵌入强度,提出了一种新的离散多小波变换域的数字图像水印算法。实验结果表明,使用此算法能提高数字水印对于各种改变的鲁棒性,同时保证数字水印的不可感知性。
Proposes the image watermarking algorithm using the discrete multiwavelet transform. Obtains performance improvement by using genetic algorithms to compute the best initial value and embedding strength. The experimental results show that the proposed algorithm yields a watermark that is invisible to human eyes and robust to various image manipulations.
