摘要 小波变换因其独特的时(空)-频多尺度分析方法,在信息处理领域得到广泛地应用与发展,基于小波域变换的水印算法将成为实用水印系统大规模应用的基础和核心技术。该文系统分析了小波域水印技术,总结并分析了隐藏模板或可识别结构、构造同步不变特征、利用原始数据的重要特征等抗几何攻击水印设计方法的特点和存在的问题,在此基础上分析了技术的发展方向。 The wavelet transform has been widely applied and development because of its unique time(space)-frequency analysis.Watermarking algorithm based on DWT domain will be the foundation and core technologies of a practical watermarking system that can be large-scale used.The paper analyzed the watermarking technology based on DWT domain,summarized and analyzed the features and problems of some designing methods against geometric distortion,which are the hidden template or identifiable structures,the constructing synchronization invariant,the use of important characteristics of the original data,and then analyzed the direction of technology development.
