Reversible Data Hiding Based on Pixel-Value-Ordering and Pixel Block Merging Strategy
Computers, Materials & Continua, 2019 With the reversible data hiding method based on pixel-value-ordering, data are embedded through the modification of the maximum and minimum values of a block. A significant relationship exists between the embedding performance and the block size. Traditional pixel-value-ordering methods utilize pixel blocks with a fixed size to embed data; the smaller ...

REVERSIBLE DATA HIDING BASED ON PIXEL-BASED PIXEL VALUE ORDERING PREDICTOR AND EMD
Scientific Journal of Tra Vinh University, 2019 In this paper, we improved the reversible data hiding method of Qu’s et al. The original image is divided into overlapped equalsize blocks (2x2). Each of block is used to predict a pixel. Then a histogram is constructed from the different value between the original pixel and the prediction pixel.

Noise Removal of Low-Dose CT Images Using Modified Smooth Patch Ordering
IEEE Access, 2017 Low-dose computed tomography (LDCT) images tend to be severely degraded by excessive mottle noise and steak artifacts. In this paper, an algorithm of modified smooth patch ordering (MSPO) is proposed to improve the LDCT images.

Dynamic Hybrid Reversible Data Hiding Based on Pixel-value-ordering
電腦學刊, 2023 <p>Reversible data hiding (RDH) using pixel-value-ordering (PVO) is a well-established technique for embedding data in a cover image by modifying the maximum and minimum in each block. This paper proposes a dynamic hybrid RDH method based on PVO.

Novel Reversible Pixel-Value-Ordering Technique for Secret Concealment
Indian Journal of Science and Technology, 2015 This work is to preserve the distortion of marked image from the original image, that is, to improve the Peak Signal-to-Noise Ratio (PSNR) and to improve the Embedding Capacity (EC). Pixel-Value-Ordering (PVO) is the technique used for ensuring reversibility in Reversible Data Hiding (RDH).
