基于混沌置乱的土家织锦图像数字水印算法

Digital Watermarking Algorithm Based on Tujia Brocade Design of Chaos Scrambling

利用混沌序列所特有的不可预测性,将混沌理论引入数字水印的创建中,给出了混沌置乱的土家织锦图像数字水印嵌入算法,实现了利用Logistic映射产生的混沌序列有序的嵌入数字水印的方法,实验证明该算法具有很好的密钥唯一性、不可见性和鲁棒性.

Due to the unpredictability property of chaotic sequence,chaos theory can be used in the process of creating the digital watermarking.A robust digital watermarking scheme based on Logistic chaotic sequences is proposed.The watermark is preprocessed by Logistic chaotic sequences and spread adaptive over the image wavelet domain.The experimental results demonstrate that the watermark is robust to general image processing techniques and geometric distortions.
