[DocumentsAdaptive_blind_watermark_algorithm

Description: 一种嵌入可读水印的自适应盲水印算法,  本文提出了一种基于DWT的嵌入可读水印的自适应盲水印算法,通过分析图像经离散小波变换后细 节子带系数的特性,把细节子带系数的均值和方差作为水印信息的一部分来自适应地修改图像小波分解后某些细节 子带的系数值,在满足水印不可感知性的条件下自适应地嵌入水印信息,实现了水印不可感知性和鲁棒性之间的折 衷. 同时,水印的提取无须求助于原图像,很好的实现了水印的盲检测. 这里的水印是一幅有实际意义的二值图像. 实 验结果和攻击测试表明,本文提出的算法对JPEG/ JPEG2000 压缩、添加噪声、剪切、像素移位等多种攻击有较强的鲁棒 性,同时对直方图均衡化、对比度调整和高斯滤波等图像处理操作也具有一定的抵抗能力.-A readable watermark embedding Adaptive Blind Watermarking Algorithm

[Special EffectsA.Blind.and.Robust.Watermarking.Scheme

Description: Abstract- H.264/AVC is becoming a popular video codec for its better compression ratio, lower distortion and applicability to portable electronic devices. Thus, issues of copyright protection appropriate for this standard become very important. In this paper, a new blind SVD (Singular Value Decomposition) - DCT combined video watermarking scheme for the ".264 standard is proposed. The proposed method is a blind watermarking algorithm as the hidden information can be extracted without the original video and the original singular values. To reduce visual quality degradation caused by coefficients modifying, the perceptual model and block selection mechanism are introduced to control the modification strength. The performance of the proposed algorithm is evaluated with respect to imperceptibility, robustness and data payload. Experimental results reveal that the proposed scheme achieves enough robustness while preserving the perceptual quality.-Abstract- H.264/AVC is becoming a popular video codec for its better compression ratio, lower distortion and applicability to portable electronic devices.

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.
