In prediction-error expansion (PEE) based reversible data hiding, better exploiting image
redundancy usually leads to a superior performance. However, the correlations among …

This paper investigates the use of local prediction in difference expansion reversible
watermarking. For each pixel, a least square predictor is computed on a square block …

A 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 …

Reversible data hiding hides data in an image such that the original image is recoverable.
This paper presents a novel embedding framework with reduced distortion called skewed …

This paper proposes a reversible data hiding scheme for encrypted images with SHE
(Somewhat Homomorphic Encryption) based on sorting block-level prediction-error …

Reversible watermarking aims to embed more messages in a cover image with less
distortion. For reversible watermarking schemes (RWSs) using the prediction error …

In this paper, a novel reversible data hiding method is proposed using an improved gradient
based prediction. The gradients are computed across horizontal, vertical, diagonal and anti …

A good prediction Error Expansion (PEE) based reversible data hiding method demands an
effective pixel prediction strategy. There are numerous pixel prediction techniques in the …

Reversible data hiding in JPEG images has become an important topic due to the
prevalence and overwhelming support of the JPEG image format these days. Much of the …

A novel reversible data hiding (RDH) technique has been proposed in this study using a B‐
tree triangular decomposition‐based prediction of image pixels. The superiority of a …
