该文介绍并分析了RGB图像的直方图特性,详细阐述了直方图的峰值点和零值点的特点和直方图平移对图像的影响。在此基础上,根据视觉特性的特点,提出了一种新的RGB图像信息隐藏算法:一种大容量的可逆RGB图像信息隐藏算法。该算法基于直方图平移和视觉特性,能解决当前基于直方图平移算法的低隐藏容量难点。实验结果及分析表明,该算法易于实现,有很好的隐蔽性并对隐藏容量有较大提高。

The article introduced and analyzed the characteristics of RGB histogram of the image, then elaborated on the charac-teristic of the peaks and zero in the histogram and the influence of image histogram shift. On this basis, according to the character-istics of the visual feature, we proposed a new RGB image information hiding algorithm:A large capacity of reversible RGB im-age information hiding algorithm. This algorithm is based on histogram shift and visual characteristics. It can solve the difficulties of the current algorithm which is based on histogram shift has low hiding capacity. The experimental results and analysis show that the algorithm is easy to implement and has good concealment, it increased greatly on hiding capacity.
