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 ...

Reversible data hiding with dual pixel-value-ordering and minimum prediction error expansion.
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 Algorithm Based on Pixel Value Ordering and Block Subdivision [PDF]
Jisuanji gongcheng, 2022 The reversible data hiding algorithm based on Pixel Value Ordering (PVO) embeds data by modifying the largest and smallest pixels in the block without completely using each pixel in image block, thereby affecting the embedding performance.Combined with ...

Reversible Data Hiding Using an Improved Pixel Value Ordering and Complementary Strategy
Symmetry, 2022 Reversible data hiding (RDH) schemes based on pixel value ordering have gained significant popularity due to their unique capability of providing high-quality marked images with a decent embedding capacity, while also enabling secret information extraction and the lossless recovery of the original images at the receiving side. However, the marked image
