摘要

提出了一个新的基于图像能量和量化的公开数字水印算法.首先对原始图像进行均匀分块

然后根据相应的水印信息和量化方法修改各个图像子块的能量以嵌入水印;水印的提取则是水印嵌入的逆过程.由于在算法中采用了量化嵌入策略

从而使该算法在提取水印时无需原始图像.实验结果表明:该算法具有很好的水印不可见性

对常见的图像处理攻击:如重采样、颜色抖动、平滑、加噪声和JPEG压缩等具有很强的稳健性.

Abstract

A novel public digital watermark algorithm based on image energy and quantization is proposed.In the algorithm

the original image is equally divided into blocks firstly

and then the energy of each sub-image of the original image is altered for embedding the watermark according to the corresponding watermark information and the quantization method.The watermark extraction is the inverse procedure of the watermark embedding.For the using of quantization scheme

the algorithm can extract watermark without original image.Experimental results show that the algorithm has a fine imperceptivity of watermark embedded and is strongly robust to attacks such as re-sampling

color dithering

smoothing

noise adding

and JPEG-compression.
