An Interplay of Ridgelet and Linear Canonical Transforms

open access: yesMathematics, 2022
The present study is the first of its kind, aiming to explore the interface between the ridgelet and linear canonical transforms. To begin with, we formulate a family of linear canonical ridgelet waveforms by suitably chirping a one-dimensional wavelet ...

Meningioma brain tumor detection and classification using hybrid CNN method and RIDGELET transform [PDF]

open access: yesScientific Reports, 2023
The detection of meningioma tumors is the most crucial task compared with other tumors because of their lower pixel intensity. Modern medical platforms require a fully automated system for meningioma detection.

Local-Ternary-Pattern-Based Associated Histogram Equalization Technique for Cervical Cancer Detection [PDF]

open access: yesDiagnostics, 2023
Every year, cervical cancer is a leading cause of mortality in women all over the world. This cancer can be cured if it is detected early and patients are treated promptly.

Scale-discretised ridgelet transform on the sphere [PDF]

open access: yesCoRR, 2019
We revisit the spherical Radon transform, also called the Funk-Radon transform, viewing it as an axisymmetric convolution on the sphere. Viewing the spherical Radon transform in this manner leads to a straightforward derivation of its spherical harmonic ...

Multivariable passive method for detection of islanding events in renewable energy based power grids

open access: yesIET Renewable Power Generation, 2022
Penetration of distributed generation resources (DGR) in power grid is rapidly increasing to meet future energy demand efficiently. It helps in mitigating the problems of high carbon emission, green house effect, and increased cost of oil and natural ...

Discrete analytical Ridgelet transform [PDF]

open access: yesSignal Processing, 2004
In this paper, we present a new implementation of the Ridgelet transform based on discrete analytical 2-D lines: the discrete analytical Ridgelet transform (DART). This transform uses the Fourier strategy for the computation of the associated discrete Radon transform.

Image denoising method integrating ridgelet transform and improved wavelet threshold. [PDF]

open access: yesPLoS ONE
In the field of image processing, common noise types include Gaussian noise, salt and pepper noise, speckle noise, uniform noise and pulse noise. Different types of noise require different denoising algorithms and techniques to maintain image quality and
