Octal Bent Generalized Boolean Functions [PDF]
, 2011 In this paper we characterize (octal) bent generalized Boolean functions defined on $\BBZ_2^n$ with values in $\BBZ_8$. Moreover, we propose several constructions of such generalized bent functions for both $n$ even and $n ...

An efficient no‐reference image quality analysis based on statistical perceptual features
IET Image Processing, Volume 19, Issue 1, January/December 2025.1. A novel and efficient feature‐based no‐reference image quality assessment (NR‐IQA) focus measure is proposed. 2. It is based on the statistical structural and texture features of the image. 3. The logarithmic entropy‐based focus measure shows promising results as compared to the existing techniques. Abstract It is well known that image quality needs

Landscape Boolean Functions [PDF]
, 2018 In this paper we define a class of Boolean and generalized Boolean functions defined on $\mathbb{F}_2^n$ with values in $\mathbb{Z}_q$ (mostly, we consider $q=2^k$), which we call landscape functions (whose class containing generalized bent, semibent ...

NoLIEM: A Novel Lightweight Image Encryption Method for Resource‐Constrained IoT Devices
IET Information Security, Volume 2025, Issue 1, 2025.The expanded use of Internet of Things (IoT) devices in smart homes, industrial automation, healthcare, and smart cities has increased the risk of unauthorized access, data breaches, and man‐in‐the‐middle attacks. Traditional encryption methods like AES and RSA are too energy‐ and processing‐intensive for IoT devices.

QROP: Quantum Learning‐Based Identification of Retinopathy of Prematurity
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.This work aims to classify normal and ROP‐affected retinal images using a quantum neural network (QNN). The proposed system uses the HVDROPDB (2023) dataset fundus images of preterm infants. The proposed system achieves 97.06% accuracy with the HVDROPDB Neo dataset, 91.18% accuracy with the HVDROPDB RetCam dataset, and 85.29% accuracy when evaluated on

Remarks on numerical approximation of Volterra integral equations by Walsh–Hadamard transform
Results in Applied MathematicsWalsh functions form a piecewise-constant orthonormal basis that is particularly well-suited for digital computation and signal approximation. Nevertheless, the direct evaluation of Walsh transforms for discrete functions becomes computationally ...
