Digital watermarking embeds a watermark to minimise the problem of illegal copying and disseminating multimedia contents. However, the existing techniques do not maintain the imperceptibility and robustness simultaneously. To achieve the same, this study proposes an optimised robust watermarking technique using chaotic kbest gravitational search algorithm. The chaotic kbest gravitational search algorithm is used to obtain the optimal values of embedding factors. The efficacy of the proposed technique has been experimented on a standard images and compared with the six recent state-of-the-art techniques in terms of imperceptibility and robustness. The experimental results validate that the proposed technique outperforms the other considered techniques.

在DCT-SVD域中使用CKGSA优化的鲁棒水印技术

数字水印嵌入水印,以最大程度地减少非法复制和传播多媒体内容的问题。但是,现有技术不能同时保持不可感知性和鲁棒性。为了达到相同的目的,本研究提出了一种使用混沌kbest引力搜索算法的优化鲁棒水印技术。混沌kbest引力搜索算法用于获得嵌入因子的最优值。已在标准图像上对所提出技术的功效进行了实验,并在不易察觉性和鲁棒性方面与六种最新技术进行了比较。实验结果验证了所提出的技术优于其他考虑的技术。
