High-Performance Reversible Data Hiding
Fundamenta Informaticae, 2008This paper proposes a high-performance reversible data hiding algorithm based on the block difference histogram of a cover image. If a message is to be embedded into an image, the difference of the block at the maximum point is increased by 1 or left unchanged if the message bit is "1" or "0", respectively.

Reversible Data Hiding Under Inconsistent Distortion Metrics
IEEE Transactions on Image Processing, 2018Recursive code construction (RCC), based on the optimal transition probability matrix (OTPM), approaching the rate-distortion bound of reversible data hiding (RDH) has been proposed. Using the existing methods, OTPM can be effectively estimated only for a consistent distortion metric, i.e., if the host elements at different positions share the same ...

CNN Prediction Based Reversible Data Hiding
IEEE Signal Processing Letters, 2021How to predict images is an important issue in the reversible data hiding (RDH) community. In this letter, we propose a novel CNN-based prediction approach by luminously dividing a grayscale image into two sets and applying one set to predict the other set for data embedding. The proposed CNN predictor is a lightweight and computation-efficient network

Reversible image processing via reversible data hiding
2016 IEEE International Conference on Digital Signal Processing (DSP), 2016Image processing is a very popular and widely used technique. In this paper, we propose a framework for realizing reversible image processing, which enables that the users can return the processed image to the original copy without loss. In the proposed method, the original image is firstly processed to get the desired target image by a classic image ...

Double-threshold reversible data hiding
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010This proposed scheme reversibly embeds data into image prediction-errors by using histogram-pair method with double thresholds (embedding threshold and fluctuation threshold). The embedding threshold is used to select only those prediction-errors, whose magnitude does not exceed this threshold, for possible reversible data hiding.

Laplacian: Reversible Data Hiding Technique
2019 Fifth International Conference on Image Information Processing (ICIIP), 2019Reversible Data Hiding (RDH) techniques are becoming more important in the present era of digital content security. In RDH the reciprocal nature of embedding capacity and visual quality parameters, hinder further visual quality enhancement. The trade-off between embedding capacity and visual quality is an essential characteristic of any data hiding ...

Hierarchy-based reversible data hiding
Expert Systems with Applications, 2013In this paper, we propose a new method for reversible data hiding by employing the hierarchical relationships of original images. There are many parameters for accessing the performances of reversible data hiding algorithms, including the output image quality, the hiding capacity, and the overhead for decoding.

Reversibility improved lossless data hiding
Signal Processing, 2009Recently, lossless data hiding has attracted increasing interests. As a reversible watermark scheme, the host media and hidden data should be recovered without distortion. A latest lossless data hiding technique based on image blocking and block classification has achieved good performance for image authentication.

Multi-resolution reversible data hiding
2014 7th International Congress on Image and Signal Processing, 2014Image reversible data hiding is the process of embedding information in an image in a visually imperceptible way with the result that both the original image and the embedded information can be exactly recovered. In the traditional approaches of histogram shifting and causal window-based difference/prediction-error expansion, pixel value prediction ...
