摘要
本文在阐述数字水印的基本概念和特点的基础上,指出数字水印结构设计和嵌入算法是决定水印鲁棒性的两个主要因素,结合人类视觉模型对水印嵌入算法的鲁棒性做了深入分析。最后介绍了当前一些改进算法的特点及数字水印技术的发展方向。
In this paper,we firstly give an overview on basic concept and characteristics of digital watermarking.Upon it,we point out two essential factors of robust for digital watermarking:structure design and embedding algorithms.Then we empha-size on the robust of embedding algorithms with human visual system.Finally we discuss some improved algorithms and prospective directions for further developments.
