Reversible data hiding using invariant pixel-value-ordering and prediction-error expansion

Signal Processing: Image Communication, 2014
Recently, Li et al. proposed a reversible data hiding (RDH) method based on pixel-value-ordering (PVO) and prediction-error expansion. In their method, the maximum and the minimum of a pixel block are predicted and modified to embed data, and the ...

High-fidelity reversible data hiding scheme based on pixel-value-ordering and prediction-error expansion

Signal Processing, 2013
This paper presents a high-fidelity reversible data hiding scheme for digital images based on a new prediction strategy called pixel-value-ordering (PVO) and the well-known prediction-error expansion (PEE) technique.

High-fidelity reversible data hiding based on pixel-value-ordering and pairwise prediction-error expansion

Journal of Visual Communication and Image Representation, 2016
Pixel-value-ordering (PVO) technique refers to the process of first ranking the pixels in a block and then modifying the maximum/minimum for reversible data hiding (RDH).

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

, 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
