Optical images-based edge detection in Synthetic Aperture Radar images [PDF]

open access: yes, 2015
We address the issue of adapting optical images-based edge detection techniques for use in Polarimetric Synthetic Aperture Radar (PolSAR) imagery. We modify the gravitational edge detection technique (inspired by the Law of Universal Gravity) proposed by

Deep Learning and Higher Degree F-Transforms: Interpretable Kernels Before and After Learning

open access: yesInternational Journal of Computational Intelligence Systems, 2020
One of the current trends in the deep neural network technology consists in allowing a man–machine interaction and providing an explanation of network design and learning principles. In this direction, an experience with fuzzy systems is of great support.

Some uniqueness theorems for a conical Radon transform

open access: yesJournal of Physics Communications, 2023
The conical Radon transform, which assigns to a given function f on ${{\mathbb{R}}}^{3}$ its integrals over conical surfaces, arises in several imaging techniques, e.g. in astronomy and homeland security, especially when the so-called Compton cameras are

Noise Suppression of Distributed Acoustic Sensing Based on f-x Deconvolution and Wavelet Transform

open access: yesIEEE Photonics Journal, 2020
A noise suppression method based on f-x deconvolution and the wavelet transform is proposed for eliminating jump edges in the phase noise of distributed acoustic sensing. Experimental results show that the proposed method has good performance in terms of

On the class of uncertainty inequalities for the coupled fractional Fourier transform

open access: yesJournal of Inequalities and Applications, 2022
The coupled fractional Fourier transform F α , β $\mathcal {F}_{\alpha ,\beta}$ is a two-dimensional fractional Fourier transform depending on two angles α and β, which are coupled in such a way that the transform parameters are γ = ( α + β ) / 2 $\gamma

Spectral denoising based on Hilbert–Huang transform combined with F-test

open access: yesFrontiers in Chemistry, 2022
Due to the influence of uncontrollable factors such as the environment and instruments, noise is unavoidable in a spectral signal, which may affect the spectral resolution and analysis result.

Loop-Effects in Pseudo-Supersymmetry [PDF]

open access: yes, 2002
We analyze the transmission of supersymmetry breaking in brane-world models of pseudo-supersymmetry. In these models two branes preserve different halves of the bulk supersymmetry.

Exploring the influence of ohmic heating on the action of baking powders and pound cake textural properties

open access: yesApplied Food Research
Ohmic heating (OH) involves application of an electric field to a conductive material, causing internal heat generation through resistance. This technology offers novel possibilities for the food industry, yet, its application within the baking industry ...

Regression Driven F--Transform and Application to Smoothing of Financial Time Series

open access: yes, 2017
In this paper we propose to extend the definition of fuzzy transform in order to consider an interpolation of models that are richer than the standard fuzzy transform.
