摘要
随着互联网应用的普及,图像传播为人们的社交生活和工作提供了便利,同时也带来了安全隐患,保护图像拥有者本身的数据所有权成为了当下亟待解决的问题之一.以图像溯源技术中数字水印技术为主要研究对象,提出了一种基于分数阶变换域的自适应联合数字水印算法,以分数变换域技术替代了传统变换域技术,使得数字水印具有更强的鲁棒性.同时,以自适应地动态选择变换阶数平衡了水印的隐蔽性和鲁棒性,保证了图像溯源的有效性.
Abstract
With the widespread use of internet applications,image dissemination has facilitated people's social lives and work,but it has also introduced security risks.Protecting the data ownership of image creators has become a pressing issue.This paper focuses on digital watermarking technology within image tracing,proposing an adaptive joint digital watermarking algorithm based on fractional-order transform domain.By utilizing fractional transform domain techniques instead of traditional transform domain methods,the digital watermark achieves greater robustness.Additionally,by adaptively selecting the transformation order,the al-gorithm balances the watermark's invisibility and robustness,ensuring the effectiveness of image tracing.
