Watermarking medical images by reversible scheme and embedding in region of non-interest

open access: yesHo Chi Minh City Open University Journal of Science - Engineering and Technology, 2013
Medical images can be divided into two regions such as region of interest (ROI) and region of non-interest (RONI). We define ROI is the region that contains information of the patient’s state.

Reversible watermarking based on PMO of triplets [PDF]

open access: yes2008 15th IEEE International Conference on Image Processing, 2008
A reversible watermarking algorithm based on piecewise modification operation(PMO) of triplets is proposed in this paper. PMO is designed to embed a bit into any two pixels while remaining the intensity sum of pixels unchanged. Two bits are embedded into a triplet by repeatedly using PMO on every two neighboring pixels.

Life after herbarium digitisation: Physical and digital collections, curation and use

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1029-1041, July 2026.
Societal Impact Statement Collections of dried plant specimens (herbaria) provide an invaluable resource for the study of many areas of scientific interest and conservation globally. Digitisation increases access to specimens and metadata, enabling efficient use across a broad spectrum of research.

Reversible Watermarking Algorithm with Distortion Compensation

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
A novel reversible watermarking algorithm with two-stage data hiding strategy is presented in this paper. The core idea is two-stage data hiding (i.e., hiding data twice in a pixel of a cell), where the distortion after the first stage of embedding can ...

Comparison of DCT, SVD and BFOA based multimodal biometric watermarking system

open access: yesAlexandria Engineering Journal, 2015
Digital image watermarking is a major domain for hiding the biometric information, in which the watermark data are made to be concealed inside a host image imposing imperceptible change in the picture.

One Yeast, Sixteen Synthetic Chromosomes, Infinite Possibilities

open access: yesYeast, Volume 43, Issue 4, Page 143-158, July 2026.
ABSTRACT The evolution of the yeast, Saccharomyces cerevisiae, from a genetically tractable model organism to a chassis for genome‐scale engineering represents one of the most influential trajectories in eukaryotic biology. The Synthetic Yeast Genome Project (Sc2.0) embodies the current height of this trajectory, having now delivered functional ...

Hyperspectral Data: Efficient and Secure Transmission

open access: yesAlgorithms, 2017
Airborne and spaceborne hyperspectral sensors collect information which is derived from the electromagnetic spectrum of an observed area. Hyperspectral data are used in several studies and they are an important aid in different real-life applications (e ...

Light‐Induced Entropy for Secure Vision

open access: yesAdvanced Materials, Volume 38, Issue 33, 12 June 2026.
This work realized a ternary true random number generator by exploiting stochastic traps emerging within multiple junction interfaces, and quantitatively validated the generation of high‐quality random numbers. Furthermore, it successfully demonstrated diverse applications, including AI‐resilient image security, thereby providing a valuable guide for ...

The Tree of Chivalry and the Black Lady: Juana of Castile's 1496 Joyous Entry into Brussels☆

open access: yesRenaissance Studies, Volume 40, Issue 3, Page 444-468, June 2026.
Abstract Kupferstichkabinett MS 78D5 (Staatliche Museen Berlin) presents an iconographic account of the Joyous Entry of Juana of Castile into Brussels on 9 December 1496. In this article, we newly identify a rare visual record of a civic contribution to a tournament within the manuscript.
