Abstract
Reversible image steganographic scheme has become one of main research contents in information hiding field in recent years. Reversibility allows the original images to be completely reconstructed without any distortion after the embedded information has been extracted. Image interpolation is a key image processing method and has been widely applied in imaging processing relevant areas, such as image reconstruction by simulating image adjacent pixels between two-dimensional images. This paper proposed a reversible and adaptive image steganographic algorithm based on a novel interpolation technology, which can improve the performance of information hiding schemes proposed before. The proposed scheme has the benefits of higher embedding capacity with lower computational complexity and better image quality. The experimental results show that the proposed scheme can gain better performance than other state-of-the-art algorithms.
