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.

Description: 随着现代信息技术的高速发展，人们对信息技术的要求越来越高。对我们所需要的信息的安全性、保密性、版权所有性更加的关注。基于此，数字水印技术就应用而生。数字水印技术就是把一些隐藏的信息嵌 。入到数字信息的载体中，数字水印技术把这些信息从一种形式转换为另一种形式，就类似于把信号从时域转换为频域后再去处理问题。数字水印可分为盲水印和非盲水印， 非盲水印系统在检测或提取水印信息时，需要原始图像而且还会影响到人们的视觉感应；盲水印系统在检测或提取水印过程中，既不需要原始载体图像，也不需要嵌入的水印，因此盲水印系统有着更加广泛的应用。-With the rapid development of modern information technology, the information technology of the increasingly high demand. Security, privacy, copyright on the information we need attention all the more. Based on this, the digital watermarking technology is applied. Digital watermarking technique is to some hidden information block. The carrier into the digital information, the digital watermarking technology the information is converted from one form to another, similar to the signal from the time domain into the frequency domain and then to deal with the problem. Digital watermarking can be divided into blind watermarking and non-blind watermark, non-blind watermarking system in testing or when extracting the watermark information, need the original image but also affect the visual perception of people blind watermarking system in detecting or watermark extraction process, does not need the original carrier image, also do not need to embed the watermark, the watermark the system has a Platform: |
