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 ...

On the Pixel Expansion of Visual Cryptography Scheme
International Journal of Digital Crime and Forensics, 2017 In this paper, we first follow Ateniese et al.'s work that provides upper bounds of the pixel expansion of visual cryptography schemes(VCSs) for more kinds of graph access structures, in which we require that a subset of parties can determine the secret if they contain an edge of the graph G.

A Novel Quantum Visual Secret Sharing Scheme
IEEE Access, 2019 Inspired by Naor et al.'s visual secret sharing (VSS) scheme, a novel n out of n quantum visual secret sharing (QVSS) scheme is proposed, which consists of two phases: sharing process and recovering process. In the first process, the color information of

Towards Shift Tolerant Visual Secret Sharing Schemes without Pixel Expansion
MATEC Web of Conferences, 2016 Naor and Shamir proposed the visual cryptography in 1995, they encrypted secret image into two meaningless random images, called shares, and it can be decrypted by human vision without any calculations.

Axioms, 2023 To improve the accuracy of color image completion with missing entries, we present a recovery method based on generalized higher-order scalars. We extend the traditional second-order matrix model to a more comprehensive higher-order matrix equivalent ...

An extended visual cryptography scheme without pixel expansion for halftone images [PDF]
2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013 Visual cryptography is a secret sharing scheme which uses images distributed as shares such that, when the shares are superimposed, a hidden secret image is revealed. In extended visual cryptography, the share images are constructed to contain meaningful cover images, thereby providing opportunities for integrating visual cryptography and biometric ...

CrossPatch-Based Rolling Label Expansion for Dense Stereo Matching
IEEE Access, 2020 We present a novel algorithm called crosspatch-based rolling label expansion for accurate stereo matching. This optimization-based approach can effectively estimate the 3D label of each pixel from huge and infinite label space and then generate a ...
