Quantum Image Watermarking Algorithm Based on Haar Wavelet Transform

IEEE Access, 2019
In this paper, a novel frequency domain quantum watermarking scheme is proposed based on the Flexible Representation of Quantum Images, which can embed a 2n1 × 2n1 binary watermark image into a 2n × 2n grayscale carrier image.

Zero Watermarking Using Convolutional Additive Self‐Attention Vision Transformer and Discrete Wavelet Transform‐Variance‐Based Feature Descriptor for Medical Image Security in Mobile Healthcare Services

Advanced Intelligent Systems, EarlyView.
A zero‐watermarking algorithm that combines a refined convolutional additive self‐attention vision transformer (CAS‐ViT) with a discrete wavelet transform variance‐based feature descriptor (DVFD) is proposed for protecting the privacy of medical images in mobile healthcare services.

An imperceptible spatial domain color image watermarking scheme

Journal of King Saud University: Computer and Information Sciences, 2019
The paper proposes a novel scheme for color image watermarking. Spatial domain techniques are used here for embedding the watermark information to generate high quality watermarked image.

Robust Zero-Watermarking of Color Medical Images Using Multi-Channel Gaussian-Hermite Moments and 1D Chebyshev Chaotic Map

Sensors, 2022
Copyright protection of medical images is a vital goal in the era of smart healthcare systems. In recent telemedicine applications, medical images are sensed using medical imaging devices and transmitted to remote places for screening by physicians and ...

Characterizing Heterogeneity in Post‐Consumer Rigid PP Packaging Waste: Implications for Object and Property‐Based Flake Sorting

Journal of Applied Polymer Science, EarlyView.
Commercial PP packaging grades span wide ranges in melt flow rate and stiffness, defining distinct application‐specific property spaces. Post‐consumer rigid PP products populate these spaces heterogeneously, with processing method and degradation shifting properties beyond virgin grade benchmarks.

RST Resilient Watermarking Scheme Based on DWT-SVD and Scale-Invariant Feature Transform

Algorithms, 2017
Currently, most digital image watermarking schemes are affected by geometric attacks like rotation, scaling, and translation (RST). In the watermark embedding process, a robust watermarking scheme is proposed against RST attacks.

Legal and ethical considerations around the use of existing illustrations to generate new illustrations in the anatomical sciences

Anatomical Sciences Education, Volume 18, Issue 3, Page 289-300, March 2025.
Abstract It is likely existing anatomical illustrations are often used as the basis for new illustrative works, given not all illustrators have access to human tissues, bodies, or prosections on which to base their illustrations. Potential issues arise with this practice in the realms of copyright infringement and plagiarism when authors are seeking to

Transformation Teams Leading the Hispanic‐Serving Institutions Movement at HSI Community Colleges

New Directions for Community Colleges, EarlyView.
ABSTRACT The Department of Education defunded discretionary grant programs for enrollment‐based minority‐serving institutions (MSIs) on September 10, 2025, yet Hispanic‐serving institutions (HSIs) still exist and must continue to adapt to their growing population of Latine/x students.

Digital Rights Activism in Multilevel Governance

European Policy Analysis, EarlyView.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...

A robust and secure watermarking algorithm based on DWT and SVD in the fractional order fourier transform domain

Array, 2022
The present paper aims to develop and validate a robust and secure watermarking algorithm. Firstly, the algorithm transforms the cover image and the watermark image separately by FRFT to obtain the amplitudes of both the cover image and watermark image ...
