Adaptive Boundary Reference-based Dual-Images Reversible Data Hiding Scheme

In this paper, a novel dual-images reversible data hiding scheme is proposed. To provide competitive hiding capacity while maintaining acceptable image quality and lightweight computation complexity. Adaptive boundary reference is introduced. Experimental results confirm that the distortion of image quality is reduced when the payload is increasing. The average PSNR remains around 60 dB when the hiding capacity is up to 20,000 bits. Moreover, the computation complexity is less and it makes our proposed dual-images reversible data hiding more suitable for telemedicine scenario.
