摘要

Reversible data hiding (RDH) has garnered significant attention from researchers due to its ability to completely restore the original images. absolute moment block truncation coding (AMBTC)-compressed images are widely used in RDH schemes. However, to obtain a large embedding capacity, several AMBTC-based RDH schemes use the decompressed pixels to carry the message bits. Therefore, stego-images cannot be decoded by traditional AMBTC decoders. In this paper, the new AMBTC-based RDH scheme is introduced to address this problem. The multi-pair value shifting technique is applied to embed data into the AMBTC code without changing the coding structure. Unlike existing AMBTC-based RDH methods that employ a large location map (LM) to ensure the correctness of the data extraction, our scheme can minimize the LM or avoid using it entirely by applying the multi-pair value shifting technique. The experimental results indicate that the proposed scheme achieves an appropriate embedding capacity while maintaining good visual quality.
