Improved K-Pass Pixel Value Ordering Based Data Hiding [PDF]
IEEE Access, 2019 K-pass pixel value ordering (PVO) is an effective reversible data hiding (RDH) technique. In k-pass PVO, the complexity measurement may lead to a weak estimation result because the unaltered pixels in a block are excluded to estimate block complexity.

Image deconvolution by local order preservation of pixels values
2016 24th European Signal Processing Conference (EUSIPCO), 2016 Positron emission tomography is more and more used in radiation oncology, since it conveys useful functional information about cancerous lesions. Its rather low spatial resolution, however, prevents accurate tumor delineation and heterogeneity assessment.

Reversible Data Hiding Scheme Based on Quad-Tree and Pixel Value Ordering [PDF]
IEEE Access, 2019 This study proposes a reversible data hiding (RDH) scheme based on pixel value ordering (PVO). RDH schemes based on PVO technique generally realize the prediction procedure by employing the sorted pixels in a block-wise manner, and then embedding secret data by expanding the prediction errors.

A Pixel Value Ordering Predictor for High-Capacity Reversible Data Hiding
2016 International Conference on Networking and Network Applications (NaNA), 2016 Reversible data hiding (RDH), also known as lossless data embedding, is increasingly attracting more attentions of academic and industry researchers intrigued by their affordances and reach. Recently, various pixel value ordering (PVO) predictors for RDH methods with remarkable embedding performance have been proposed. These PVO-based schemes have good

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.

Generalized PVO‐based dynamic block reversible data hiding for secure transmission using firefly algorithm [PDF]
, 2022 In this paper, we proposed a novel generalized pixel value ordering–based reversible data hiding using firefly algorithm (GPVOFA). The sequence of minimum and maximum number pixels value has been used to embed the secret data while prediction and ...

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).

A DWT Ordering Scheme for Hiding Data in Images Using Pixel Value Difference
2012 Eighth International Conference on Computational Intelligence and Security, 2012 A scheme is proposed to hide data in images based on a prioritised ordering of the content of the host image. The embedding process uses the watermark strength to determine the ordering of the 16 regions resulting from the second level wavelet transform DWT decomposed content of the host image.
