| 摘 要： | 提出一种改进基于游程编码和直方图对二值无损数据隐藏算法的新方法.先对载体二值图像进行"与"操作或"异或"操作的预处理,再利用基于游程编码的直方图对的二值图像无损数据隐藏方法进行数据嵌入.实验表明,该方法在嵌入容量和视觉效果都优于改进前的方法.

| Abstract: | The paper presents a novel method which enhances the capability of the reversible binary image data hiding scheme using run-length(RL)histogram modification algorithm.Before adopting the reversible binary image data hiding scheme using histogram RL modification algorithm,some pretreatments like AND operation and XOR operation are processed first.Experimental results prove its superiority to other methods. |

| Keywords: | pretreatment binary image reversible data hiding run-length histogram pair |
