提出了一种新的可逆数字水印方案。该方案使用一种内插技术来产生称为内插误差的残差值。此外，本方案还对这些内插误差进行加性展开，实现了一种在不牺牲嵌入容量的前提下保证高图像质量的高效可逆水印方案。实验结果表明，所提出的可逆方案对水印图像具有较高的容量和较好的图像质量。该方案计算量小。
In this paper presents a novel reversible watermarking scheme. The proposed scheme use an interpolation technique to generate residual values named as interpolation error. Additionally apply the additive expansion to these interpolation-errors, this project achieve a highly efficient reversible watermarking scheme which can guarantee high image quality without sacrificing embedding capacity. The experimental results show the proposed reversible scheme provides a higher capacity and achieves better image quality for watermarked images. The computational cost of the proposed scheme is small.
