摘要
根据HVS的特性,人类视觉系统对高位信号敏感,去掉图像最低几个位并不会造成画面质量的明显下降,视觉系统就无法感觉到信号的存在,提出了四比特图像信息替换算法实现图像隐藏,运用MATLAB软件进行算法实现,嵌入信息后的载体图像与原始图像视觉效果基本一致,有效解决了图像信息隐藏问题。
According to the characteristics of HVS,The human visual system is sensitive to the high signal. To remove the image of the least number of bits does not cause a significant decline in the quality of picture,the visual system can not feel the existence of the signal. In this paper,four bit image information replacement algorithm is proposed to realize the image hiding,MATLAB software is used to realize the algorithm. The carrier image after embedding information is basically consistent with the original image,effectively solve the problem of image information hiding.
