Reversible data hiding algorithm based on asymmetric histogram shifting

open access: yes网络与信息安全学报, 2019
The shifting of two asymmetric histograms in opposite directions in data embedding respectively had produced the pixel compensation and restore effect,a better reversible data hiding algorithm based on pixel prediction was proposed,two asymmetric ...

Nonlinear Error Correction for Color Phase-Shifting Profilometry with Histogram Equalization

open access: yesPhotonics, 2022
Because color patterns with multiple channels can carry more information than gray patterns with only one channel, color phase-shifting profilometry (CPSP) has been widely used for high-speed, three-dimensional (3D) shape measurement.

An Efficient Prediction-and-Shifting Embedding Technique for High Quality Reversible Data Hiding

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
The embedding capacity of a histogram-based reversible data hiding technique is primarily determined by the peak height of the histogram. Recently, some studies have tried to embed data in the histogram of prediction errors by modifying the error values ...

Border following–based reversible watermarking algorithm for images with resistance to histogram overflowing

open access: yesInternational Journal of Distributed Sensor Networks, 2020
Histogram shifting is an effective manner to achieve reversible watermarking, which works by shifting pixels between the peak point and its nearest zero point in histogram to make room for watermark embedding.

A Robust and Reversible Watermarking Algorithm for a Relational Database Based on Continuous Columns in Histogram

open access: yesMathematics, 2020
Due to the discreteness of integer data, there are a large number of gaps and continuous columns in the histogram based on integer data. Aiming at the characteristics, this paper presents a robust and reversible watermarking algorithm for a relational ...

Secure Reversible Data Hiding in Images Based on Linear Prediction and Bit-Plane Slicing

open access: yesMathematics, 2022
Reversible Data Hiding (RDH) should be secured as per requirements to protect content in open environments such as the cloud and internet. Integrity and undetectability of steganographic images are amongst the main concerns in any RDH scheme.

Trace Concealment Histogram-Shifting-Based Reversible Data Hiding with Improved Skipping Embedding and High-Precision Edge Predictor (ChinaMFS 2022)

open access: yesMathematics, 2022
Reversible data hiding (RDH) is a special class of steganography, in which the cover image can be perfectly recovered upon the extraction of the secret data. However, most image-based RDH schemes focus on improving capacity–distortion performance.
