Description: 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 algorithm, Chaos with random noise and the likelihood of extreme sensitivity to initial conditions and so on. Two-dimensional chaotic map will be scrambling after the digital watermark embedded image signal of the low-frequency coefficients in wavelet domain, the realization of a digital watermark hidden, security and stability the use of two-dimensional chaotic map on Arnold transform scrambling watermark signal, not only enhances the confidentiality of the watermark signal at the same time improve the visual image shear resistance attacks.

Description: 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 images (ROI) of the blind detection watermarking algorithm will contain important pathological information of gray image as digital watermark, after scrambling after the chaotic sequence embedded into the host under the control of wavelet-domain Non-interest area. The experimental results show that the algorithm in the protection of medical ROI while increasing watermark robustness against JPEG compression, and tampering, cropping, filtering Dengjun has good robustness and transparency, but also enhanced the system chaotic sequence security.
