IEEE Signal Processing Letters, 2019 Pixel-value-ordering (PVO) is a new technique for the high-fidelity reversible data hiding (RDH). It contains a process of sorting the pixels of a block by their values at first and then embedding into data bits into the maximum or minimum pixels of a ...

Reversible Data Hiding Based on Pixel-Value-Ordering and Pixel Block Merging Strategy
Computers, Materials & Continua, 2019 With the reversible data hiding method based on pixel-value-ordering, data are embedded through the modification of the maximum and minimum values of a block.

AN EFFECTIVE REVERSIBLE DATA HIDING METHOD BASED ON PIXEL-VALUE-ORDERING
Journal of Computer Science and Cybernetics, 2020 This paper presents a new effective reversible data hiding method based on pixel-value-ordering (iGePVO-K) which is improvement of a recent GePVO-K method that recently is considered as a PVO-used method having highest embedding capacity.

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-distortion performance. Particularly, we propose to embed in two phases:forwardandbackward.

A hybrid steganography scheme with reduced difference expansion and pixel-value ordering
IAES International Journal of Artificial Intelligence (IJ-AI)Steganography embeds secret messages into public media while ensuring the stego content remains visually indistinguishable from the original. The primary challenge lies in maximizing embedding capacity and image quality without introducing noticeable ...

High-Capacity Reversible Data Hiding Using Modified Pixel Value Ordering Approach
Journal of Circuits, Systems and Computers, 2018 The proposed reversible data hiding technique is the extension of Peng et al.’s technique [F. Peng, X. Li and B. Yang, Improved PVO-based reversible data hiding, Digit. Signal Process. 25 (2014) 255–265].

Information Sciences, 2020 Abstract The existing reversible data hiding (RDH) methods based on improved pixel value ordering (IPVO) use only a small portion of the pixels (e.g., at most six pixels) in a block for embedding data. Our proposed method is a dynamic IPVO RDH, which can flexibly modify the number of pixels in a block by classifying the local complexity into multiple
