本文提出了基于二维混沌映射的数字图像水印算法，混沌具有随机性、似噪声及对初始条件的极端敏感性等特点。将经过二维混沌映射置乱后的数字水印信号嵌入图像小波域的低频系数，实现了数字水印的隐蔽性、保密性和稳固性；利用二维混沌映射Arnold变换对水印信号进行置乱，不仅增强了水印信号保密性，同时有效提高了视觉上抵抗图像剪切攻击的能力。-In this paper, two-dimensional chaotic map based on digital image watermarking algorit

摘 要: 提出了一种基于医学图像中感兴趣区域(ROI)的盲检测水印算法, 将包含重要病理信息的灰度图像作为数字水印, 经置乱后在混沌序列的控制下嵌入到宿主小波域非感兴趣区域中。实验结果表明, 该算法在保护医学 ROI 的同时提高了水印抗 JPEG 压缩的鲁棒性, 并对篡改、 几何剪切、 滤波等均具有良好的鲁棒性和透明性, 而且混沌序列增强了系统的安全性。-Abstract: This paper presents a region of interest based on medical ima
