XOR-Based (n, n) Visual Cryptography Schemes for Grayscale or Color Images with Meaningful Shares
Applied Sciences, 2022 XOR-based Visual Cryptography Scheme (XOR-based VCS) is a method of secret image sharing. The principle of XOR-based VCS is to encrypt a secret image into several encrypted images, called shares.

Pixel grafting: A novel skin graft expansion technique
Journal of Cutaneous and Aesthetic Surgery, 2021 Skin grafting is the transplantation of skin, a routinely performed procedure to cover the loss of skin. Skin is the largest organ of the body, which falls short of availability in extensive injuries, especially burns. In such a situation, pixel grafting, a novel expansion technique helps to cover a large area with less skin harvest.

Visual cryptography scheme on graphs with $m^{*}(G)=4$ [PDF]
Transactions on Combinatorics, 2019 Let $G=(V,E)$ be a connected graph and $\Gamma (G)$ be the strong access structure where obtained from graph $G$. A visual cryptography scheme (VCS) for a set $P$ of participants is a method to encode a secret image such that any pixel of this image ...

Analysis and design of visual secret sharing scheme for gray image
网络与信息安全学报, 2020 Existing gray visual secret sharing (GVSS) convert the original image into black-white binary image for processing,which causes the pixel information loss problem.For this purpose,a kind of GVSS based on gray superposition was proposed.For each gray ...

Reversible Data Hiding Based on Pixel-Value-Ordering and Prediction-Error Triplet Expansion
Mathematics, 2021 Pixel value ordering and prediction error expansion (PVO+PEE) is a very successful reversible data hiding (RDH) scheme. A series of studies were proposed to improve the performance of the PVO-based scheme. However, the embedding capacity of those schemes
