Reversible Data Hiding Based on Pixel-Value-Ordering and Prediction-Error Triplet Expansion

Pixel value ordering and prediction error expansion (PVO+PEE) is a very successful reversible data hiding (RDH) scheme. A series of studies were proposed to improve the performance of the PVO-based scheme. However, the embedding capacity of those schemes is quite limited. We propose a two-step predi...
