The Magic of Nonlocal Perona–Malik Diffusion

IEEE Signal Processing Letters, 2011
In this letter, we show that it is possible to obtain perfect reconstruction of the 256 X 256 phantom image from only 8 radial lines in the Fourier domain by a nonlocal extension of Perona-Malik diffusion.

Nonlocal electrical diffusion equation

International Journal of Modern Physics C, 2016
In this paper, we present an analysis and modeling of the electrical diffusion equation using the fractional calculus approach. This alternative representation for the current density is expressed in terms of the Caputo derivatives, the order for the space domain is [Formula: see text] and for the time domain is [Formula: see text].

Asymptotic stability of the nonlocal diffusion equation with nonlocal delay

Mathematical Methods in the Applied Sciences
This work focuses on the asymptotic stability of nonlocal diffusion equations in ‐dimensional space with nonlocal time‐delayed response term. To begin with, we prove and ‐decay estimates for the fundamental solution of the linear time‐delayed equation by Fourier transform.

Nonlocal Reaction-diffusion Equations

2014
We introduced nonlocal reaction-diffusion equations in Section 2.4 of Chapter 1 by means of the model of competition of species. It is also possible to view them in a different way. If individuals of some population consume resources in some area around their average position, then we need to take into account this nonlocal consumption of resources in ...
