A Novel Reversible Data Hiding Method for Color Images Based on Dynamic Payload Partition and Cross-Channel Correlation

The traditional color image reversible data hiding (RDH) techniques mainly focus on utilizing inter-channel correlations to improve embedding performance, but mostly have poor time efficiency. Nevertheless, the information redundancy in the color image is not fully exploited. In this paper, a new sorting strategy and a payload partition scheme are proposed. Thus, a novel RDH method for color images is proposed based on existed PEE algorithm. Extensive experimental results demonstrate that the proposed method achieves better performance comprehensively considering distortion control and time efficiency than prior state-of-the-art methods.
