Reversible data hiding with dual pixel-value-ordering and minimum prediction error expansion. [PDF]
PLoS ONE, 2022 Pixel Value Ordering (PVO) holds an impressive property for high fidelity Reversible Data Hiding (RDH). In this paper, we introduce a dual PVO (dPVO) for Prediction Error Expansion (PEE), and thereby develop a new RDH scheme to offer a better rate ...

Reversible Data Hiding Based on Pixel-Value-Ordering and Prediction-Error Triplet Expansion
Mathematics, 2021 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

Reversible Watermark with Large Capacity Based on the Prediction Error Expansion [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2008 A reversible watermark algorithm with large capacity has been developed by applying the difference expansion of a generalized integer transform. In this algorithm, a watermark signal is inserted in the LSB of the difference values among pixels. In this paper, we apply the prediction errors calculated by a predictor in JPEG-LS for embedding watermark ...
