Quantization-Based Image Watermarking by Using a Normalization Scheme in the Wavelet Domain

Information, 2018
To improve the invisibility and robustness of quantization-based image watermarking algorithms, we developed an improved quantization image watermarking method based on the wavelet transform and normalization strategy used in this study.

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.

MaX4Zero: Masked Extended Attention for Zero‐Shot Virtual Try‐On In The Wild

Computer Graphics Forum, EarlyView.
Max4Zero is a zero‐shot, training‐free virtual try‐on method that leverages diffusion priors and extended attention for accurate garment transfer. By warping reference garments and mitigating texture sticking, it achieves superior fidelity, garment preservation and identity consistency over state‐of‐the‐art methods without additional training ...

Designing Annotations in Visualization: Considerations from Visualization Practitioners and Educators

Computer Graphics Forum, EarlyView.
Abstract Annotation is a central mechanism in visualization design that enables people to communicate key insights. Prior research has provided essential accounts of the visual forms annotations take, but less attention has been paid to the decisions behind them.

Do deepfakes, digital replicas and human digital twins justify personality rights?

The Journal of World Intellectual Property, EarlyView.
Abstract Unauthorised deepfakes are deeply problematic, from the spreading of misinformation to non‐consensual pornographic content. This paper asks whether deepfakes, digital replicas and human digital twins justify personality rights. To address this question, it examines the harms that deepfakes can cause through disinformation, demeaning content ...

A robust watermarking technique based on image normalization

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
This paper presents a robust watermarking method against geometric distortions and several other signal processing schemes. In the proposed watermarking method, image normalization is used to get geometric invariant features. The watermark embedding and

Mask Image Watermarking

CoRR
We present MaskWM, a simple, efficient, and flexible framework for image watermarking. MaskWM has two variants: (1) MaskWM-D, which supports global watermark embedding, watermark localization, and local watermark extraction for applications such as tamper detection; (2) MaskWM-ED, which focuses on local watermark embedding and extraction, offering ...

The Diremption of Meaning

Modern Theology, EarlyView.
Abstract Examining work by Rowan Williams, this essay explores what he often refers to as the ‘difficulty’ of writing theology. The difficulty of theology lies in engaging the ruse of having ultimate answers to ultimate questions. The stakes are high: ‘God‐talk’ must concern itself with truth, with reality.
