A Novel Quantum Visual Secret Sharing Scheme
IEEE Access, 2019 Inspired by Naor et al.'s visual secret sharing (VSS) scheme, a novel n out of n quantum visual secret sharing (QVSS) scheme is proposed, which consists of two phases: sharing process and recovering process. In the first process, the color information of

Efficient Reversible Data Hiding Using Two-Dimensional Pixel Clustering
, 2023 Pixel clustering is a technique of content-adaptive data embedding in the area of high-performance reversible data hiding (RDH). Using pixel clustering, the pixels in a cover image can be classified into different groups based on a single factor, which ...

An extended visual cryptography scheme without pixel expansion for halftone images [PDF]
2013 26th IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2013 Visual cryptography is a secret sharing scheme which uses images distributed as shares such that, when the shares are superimposed, a hidden secret image is revealed. In extended visual cryptography, the share images are constructed to contain meaningful cover images, thereby providing opportunities for integrating visual cryptography and biometric ...

CrossPatch-Based Rolling Label Expansion for Dense Stereo Matching
IEEE Access, 2020 We present a novel algorithm called crosspatch-based rolling label expansion for accurate stereo matching. This optimization-based approach can effectively estimate the 3D label of each pixel from huge and infinite label space and then generate a ...
