摘要

对图像BOR(Balanced Optimal-Reconstruction)多小波分解后的系数进行了详尽地分析

提出图像多小波变换的分层性(不同于分解的级数)观点.针对这一特点

待隐藏的信息可分层嵌入图像BOR多小波域

这为隐藏算法又提供了一个密钥.将可读的自适应盲水印信息分别嵌入图像BOR域第一层子图和同时嵌入四层子图中.仿真实验表明

两种方案嵌入的水印图像拥有优良的不可感知性和强健的鲁棒性.

Abstract

On base of detailed analysis of the decomposed coefficients of BOR multiwavelet

the "layer" concept of an image in MWD (multiwavelet domain) was proposed.For this unique character

data can be hidden in different layer subimages

the selection of hiding layer undoubtedly gives another secret key.An adaptive blind watermarking algorithm is put forward to embed a binary image into the first layer subimage and four layers respectively according to above trait.Experimental results show that the two given methods have good imperceptibility and high robustness.
