DCT-Based Zero Replacement Reversible Image Watermarking Approach [PDF]

, 2013
Reversible watermarking recovers an original image from a watermarked image by extracting the embedded watermarks. This work presents a reversible image watermarking approach that works on quantized DCT coefficients, implying that the original quantized ...

Deep Robust Reversible Watermarking

IEEE Transactions on Pattern Analysis and Machine Intelligence
Robust Reversible Watermarking (RRW) enables perfect recovery of cover images and watermarks in lossless channels while ensuring robust watermark extraction in lossy channels. Existing RRW methods, mostly non-deep learning-based, face complex designs, high computational costs, and poor robustness, limiting their practical use.

A “Tech First” Approach to Foreign Policy? The Three Meanings of Tech Diplomacy

Global Policy, EarlyView.
ABSTRACT Scholars have recently argued that international politics is plagued by instability as the world rapidly transitions from one crisis to another. This state of “Permacrisis,” or permanent crises between states, is driven by technological innovations which create new kinds of crises and drive competitions between adversarial states.

Efficient Reversible Data Hiding Based on Connected Component Construction and Prediction Error Adjustment

Mathematics, 2022
To achieve a good trade-off between the data-embedding payload and the data-embedding distortion, mainstream reversible data hiding (RDH) algorithms perform data embedding on a well-built prediction error histogram.

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

PLANTS, 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.

Light‐Induced Entropy for Secure Vision

Advanced 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 ...
