Multiple moduli prediction error expansion reversible data hiding

Signal Processing: Image Communication, 2019
Abstract This manuscript considers the distinct prediction error expansion (PEE) of each pixel up to the limit of overflow/underflow in view of embedding a maximum amount of data. A moduli map is created by associating to each pixel its expansion modulus. Since the storing of the expansion moduli map requires more free space than the room provided by

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.

Reversible watermarking by prediction-error expansion

6th IEEE Southwest Symposium on Image Analysis and Interpretation, 2004., 2004
We propose a new reversible (lossless) watermarking algorithm for digital images. Being reversible, the algorithm enables the recovery of the original host information upon the extraction of the embedded information. The proposed technique exploits the inherent correlation among the adjacent pixels in an image region using a predictor.

Reversible data hiding using additive prediction-error expansion

Proceedings of the 11th ACM workshop on Multimedia and security, 2009
Reversible data hiding is a technique that embeds secret data into cover media through an invertible process. In this paper, we propose a reversible data hiding scheme that can embed a large amount of secret data into image with imperceptible modifications. The prediction-error, difference between pixel value and its predicted value, is used to embed a

Reversible Data Hiding for Audio Based on Prediction Error Expansion

2008 International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2008
This paper proposes a reversible data hiding method for digital audio using prediction error expansion technique. Firstly, the prediction error of the original audio is obtained by applying an integer coefficient predictor. Secondly, a location map is set up to record the expandability of all audio samples, and then it is compressed by lossless ...

Reversible watermarking of 3D mesh models by prediction-error expansion

2008 IEEE 10th Workshop on Multimedia Signal Processing, 2008
In this paper, a reversible watermarking algorithm is proposed for 3D mesh models based on prediction-error expansion. Firstly, we predict a vertex position by calculating the centroid of its traversed neighbors. Then the prediction error, i.e. the difference between the predicted and real positions, is expanded for data embedding.

Reversible watermarking based on multi-dimensional prediction-error expansion

Multimedia Tools and Applications, 2018
The reversible watermarking algorithm has been extensively studied in the field of information security in recent years, and prediction-error expansion (PEE) is a widely used technology for reversible watermarking embedding. Ou et al. (IEEE Trans Image Process 22(12):5010–5021, 2013) proposed a two-dimensional histogram shifting method to extend the ...

Reversible Watermarking Based on Adaptive Prediction Error Expansion

2019
In traditional prediction error expansion (PEE) based reversible watermarking (RW), the watermark bits are embedded into the two peaks of the global prediction error histogram. This scheme ignores some bins in local histogram. To improve the utilization of prediction error, a method based on locally adaptive PEE is proposed.

Efficient reversible image watermarking by using dynamical prediction-error expansion

2010 IEEE International Conference on Image Processing, 2010
Reversible watermarking is a special watermarking technique which allows one to extract both the hidden data and the exact original signal from the watermarked content. In this paper, a recently introduced reversible image watermarking method based on prediction-error expansion is further investigated and improved.

Reversible image water marking based on prediction-error expansion and compensation

2011 IEEE International Conference on Multimedia and Expo, 2011
Prediction-error expansion (PEE) develops Tian's difference expansion technique by performing reversible data embedding in the prediction-error histogram. As the prediction accuracy greatly affects the embedding performance, the PEE-based algorithms depend heavily on image's spatial redundancy.
