摘要

本文提出一种基于混沌映射的强鲁棒性数字图像水印算法

首先用一混沌动态系统对水印信息进行预处理

而后将其扩频调制在图像空间域

并且使水印嵌入强度自适应于图像;通过预置已知模板和嵌入多块水印可实现水印检测位置的几何校准.实验结果表明

采用该算法实现的水印对常见的图像处理和几何变换具有很好的鲁棒性.

Abstract

This paper presents a robust digital image watemarking algorithm based on chaotic mapping.The watermark is preprocessed with a chaotic dynamical system and spread adaptively over the image spatial domain.Geometric calibration before watermark detection can be achieved through a preset known mask and the watermark multiple embedding.The experimental results demonstrate that the watermark is robust to general image processing techniques and geometric distortions.
