Pixel-based pixel value ordering predictor for high-fidelity reversible data hiding
Signal Processing, 2015A pixel-value-ordering (PVO) predictor has been used in reversible data hiding methods to produce high-fidelity marked images when the payload size is moderate. The original PVO generates predictions in a block-by-block manner where only two pixels can be predicted in each block. In this paper, a novel pixel-based PVO (PPVO) is proposed with which each

Hybrid prediction-based pixel-value-ordering method for reversible data hiding
Journal of Visual Communication and Image Representation, 2021Abstract Pixel-value-ordering (PVO) is an effective and promising method of reversible data hiding (RDH) and has received much attention in recent years. To improve performance, a pixel-based PVO (PPVO) method was recently introduced to predict the pixels to be embedded in a pixel-wise manner instead of the block-wise manner used by PVO. However, for

An Insight into Pixel Value Ordering Prediction Based Prediction-error Expansion
IEEE Transactions on Information Forensics and Security, 2020As the core of prediction-error expansion technique, prediction method has a fundamental impact on performance of reversible data hiding. Pixel value ordering (PVO) prediction has been extensively investigated for its high accuracy. However, the correlation of pixels within block has not been fully exploited yet.

Information Sciences, 2015
Recently, various efficient reversible data-hiding schemes based on pixel value ordering have been proposed for embedding messages into high-fidelity images. In these schemes, after dividing the cover image into equal-sized blocks, the pixels within a given block are ordered according to their values, and data embedding is achieved by modifying the ...

A generalized pixel value ordering data hiding with adaptive embedding capability
The Journal of Supercomputing, 2019In this paper, we proposed an improvisation to Li et al.’s pixel value ordering (PVO) method and called it as generalized PVO (GePVO), which provides a suitable expansion strategy using the image redundancy more abundantly. GePVO makes use of a reference pixel and calculates prediction errors using both sides of the block in different modes (one-way ...

Local feature-based mutual complexity for pixel-value-ordering reversible data hiding
Signal Processing, 2023In reversible data hiding, pixel-value-ordering (PVO) has become a widely used framework benefiting from its high-fidelity under low-capacity requirements. As an essential element in PVO-based methods, complexity could effectively avoid embedded images from unnecessary embedding distortions.

High-fidelity reversible data hiding by Quadtree-based pixel value ordering
Multimedia Tools and Applications, 2018Recently, the pixel value ordering (PVO) method has received a great deal of attention in the field of high-fidelity reversible data hiding. To improve the embedding performance of the PVO-based method, a quadtree-based pixel value ordering (QPVO) method based on dynamic quadtree partition is proposed in this paper. Instead of using equal-sized blocks,

Overlapping pixel value ordering predictor for high-capacity reversible data hiding
Journal of Real-Time Image Processing, 2019In recent years, many reversible information hiding methods have been proposed. Among them, the pixel value ordering (PVO) method can be used to create high-fidelity camouflage images under good embedding capacity. The original PVO method adopted the block-by-block manner, and each block could embed only 2 bits. In this study, we propose an overlapping

Improved Pairwise Pixel-Value-Ordering for High-Fidelity Reversible Data Hiding
2018 25th IEEE International Conference on Image Processing (ICIP), 2018Pixel-value-ordering (PVO) appears as an efficient technique for high-fidelity reversible data hiding. This paper proposes a reversible data hiding scheme based on the pairwise PVO framework with improved difference equations. Both the pixel pair selection and the embedding algorithms are also streamlined.
