灰度水印算法分析及理论研究-analysis and theoretical research of gray watermark algorithm
formula and the second fusion method. The experimental results show that this technique achieves good perceptual invisibility and security, and is also very robust against some image processing such as cropping, addition of noise, scribbling, filtering, rotation and JPEG compression.To a kind of gray-scale watermarking system, we analysis the relationship of the embedding strength, the robustness and the invisibility, from which we obtain the quantitative descriptions among them and give a compromise between invisibility and the robustness. These results provide certain theory instruction for the design of watermarking algorithms.Keywords: Gray-scale Watermark, Fractal Coding, Collage Error, Multiple Input Multiple Output, Characteristic Signal.目录中文摘要......................................................................................................................................I英文摘要.....................................................................................................................................II1 绪论..................................................................................................................................... 11.1 选题的背景........................................................................................................................... 11.2 信息隐藏与数字水印........................................................................................................... 21.3 数字水印的分类................................................................................................................... 21.4 数字水印的应用................................................................................................................... 31.4.1 版权保护 .................................................................................................................... 31.4.2 所有权认证及完整性校验 ........................................................................................ 41.4.3 使用控制 .........................................................
