| 摘 要： | 为了提供较大的秘密信息嵌入量并保持良好的载密图像质量,提出一种基于SOM(自组织特征映射神经网络)和HVS(人眼视觉特性)的小波域图像隐写.该方法先将载体图像分成固定大小的小块,以小波对比度之和以及小波系数方差作为特征量.然后,利用SOM将小块分为三类.最后,采用模算子隐写将秘密信息嵌入到小波系数中.实验结果表明,与WHS算法相比,该算法有更大的嵌入量并保持了良好的载密图像质量. |

| Abstract: | To provide larger capacity of the hidden secret data and to maintain a good visual quality of stego-image,a novel steganographic method on wavelet domain based on SOM(Self-organizing Map Nerve Net)and HVS(Human Visual System)is presented.Firstly,an image is divided into blocks,and the sum of wavelet contrast and the variance of wavelet coefficients are features.Then,those blocks are classified into 3 classes by SOM.Finally,secret information is embedded into the wavelet coefficients with steganography based... |
