Efficient Reversible Watermarking Based on Adaptive Prediction-Error Expansion and Pixel Selection

IEEE Transactions on Image Processing, 2011
Prediction-error expansion (PEE) is an important technique of reversible watermarking which can embed large payloads into digital images with low distortion. In this paper, the PEE technique is further investigated and an efficient reversible watermarking scheme is proposed, by incorporating in PEE two new strategies, namely, adaptive embedding and ...

Optimal pixel expansion of deterministic visual cryptography scheme

Multimedia Tools and Applications, 2013
The optimal pixel expansion is an important parameter of deterministic visual cryptography scheme (DVCS). There are many researches have been done under different access structures and stacking operations. However, any necessary or sufficient condition has not been found about the optimal pixel expansion. In this paper, we give a necessary condition of

An Insight into Pixel Value Ordering Prediction Based Prediction-error Expansion

IEEE Transactions on Information Forensics and Security, 2020
As 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.

Minimizing Pixel Expansion in Visual Cryptographic Scheme for General Access Structures

IEEE Transactions on Circuits and Systems for Video Technology, 2015
Given a secret image $S$ , a set $\mathscr {P}$ of $n$ participants and a strong access structure ( $\Gamma _{\mathrm {\mathbf {Qual}}}$ , $\Gamma _{\mathrm {\mathbf {Forb}}})$ , a visual cryptographic scheme (VCS) for general access structures (GVCS) encodes $S$ into $n$ shares of transparencies such that the ...

(2,3) RIVC Scheme in Visual Cryptography without Pixel Expansion

2013 2nd International Conference on Advanced Computing, Networking and Security, 2013
Region Incrementing Visual Cryptography (RIVC) was first introduced by R Z Wang in 2009. (2, n) region incrementing visual cryptographic scheme gradually reconstructs the secrets in a single image with multiple security levels. But Wang's scheme suffers from color reversal and pixel expansion.
