摘要

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.

Abstract

We propose an adaptive blind watermarking algorithm to embed readable watermark in the wavelet domain.By analyzing the characteristic of detail subband coefficients of the image after Discrete Wavelet Transform

we use the mean and variance of the detail subbands to modify the wavelet coefficients adaptively

and the embedded watermark is invisible to human eyes and adapted to the original image.This is a blind watermark algorithm to confirm the copyright without the original image and the watermark is a meaningful binary image.The experimental results and attack analysis show that the proposed algorithm is effective and robust to common image processing operations and some geometric attacks

such as JPEG/JPEG2000 lossy compression

additive noise

cropping

pixel-shift

and so on.
