Reversible data hiding is a technique not only the secret data can be extracted from a covered image but also the cover image can be completely rebuilt after the extraction process. Therefore, it is the choice in cases of secret data hiding where the full recovery of the cover image is essential. In this paper, we propose a reversible data hiding technique based on Neighbor Mean Interpolation (NMI) method utilizing the R-weighted Coding Method (RCM). Experimental results show the practicability and superiority of the proposed method over its classical counterparts, providing high performance in terms of PSNR and data hiding capacity.
