An Improved Reversible Watermarking Based on Pixel Value Ordering and Prediction Error Expansion

2020
In this paper, a new pixel value ordering (PVO) and prediction error Expansion (PEE) based reversible watermarking method is proposed. PVO based method firstly introduced by Li et al.’s has been concerned and expanded because it can achieve high embedding capacity without losing the implication of the cover.

Adaptive pixel targeting and filtering with adjacency variations in second-order derivatives of pixel values for SEM images

2016 International Conference on Robotics, Automation and Sciences (ICORAS), 2016
The proposed method utilizes histograms of second-order derivatives of the values of the pixels in an SEM image. The histograms of second-order values can express the variation in pixel values due to the effect of noise. The histograms are used as the basis for a technique to target pixels for filtering.

Pixel Filtering and Reallocation with Histograms of Second-Order Derivatives of Pixel Values for Electron Microscope Images

International Journal of Innovative Computing, Information and Control, 2018
The proposed method uses second-order derivatives to derive more information from the gray values of the pixels in a scanning electron microscope image. It represents this information as a histogram of second-order values, which expresses the variation in pixel values caused by image details and noise. The method uses the histogram as the basis for the
