Interpolation based reversible hiding scheme by using center folding strategy and adjusting hiding operator

Reversible data hiding (RDH) scheme has been widely used in many applications. One of the techniques which used in RDH is interpolation hiding data technology (IHDT). The paper proposed an IHDT based RDH scheme by using the concept of Center Folding Strategy (CFS). To improve the image quality of the stego-image, the proposed scheme adopts the enhanced neighbor means interpolation (ENMI) technique to generate the interpolated image. Furthermore, the proposed scheme refers the original image to flexibly adjust the embedding equation such that the stego-pixel can closer to the original value. The experimental results show that the proposed scheme can get better experimental results.
