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

Improved K-Pass Pixel Value Ordering Based Data Hiding [PDF]

IEEE Access, 2019
K-pass pixel value ordering (PVO) is an effective reversible data hiding (RDH) technique. In k-pass PVO, the complexity measurement may lead to a weak estimation result because the unaltered pixels in a block are excluded to estimate block complexity. In

Reversible Data Hiding Scheme Based on Quad-Tree and Pixel Value Ordering [PDF]

IEEE Access, 2019
This study proposes a reversible data hiding (RDH) scheme based on pixel value ordering (PVO). RDH schemes based on PVO technique generally realize the prediction procedure by employing the sorted pixels in a block-wise manner, and then embedding secret ...
