| 摘 要： | 针对JPEG2000基本压缩编码的特点,提出了一种应用于隐蔽通信的基于小波域统计特征的隐写算法.该算法首先利用置乱变换对待隐藏图像进行变换处理,并对载体图像进行多分辨率小波分解,然后根据人类视觉系统的掩蔽特性选择重要小波系数,将隐秘信息分别嵌入到重要小波系数的不同频率域中.实验结果表明,算法提高了信息隐藏的容量,较好地...

| Abstract: | A steganography algorithms based on wavelet domain statistical features, used in the covert communication, is proposed for the JPEG2000 baseline system. The algorithm uses the scrambing transformation to transform the hide images,and Multi-resolution wavelet decomposition to the carrier image,then according to the masking properties of human visual system to select the important the wavelet coefficients,the secret information will be embedded into the different frequency domain of the significant wavelet co... |
