Image recovery from rotational and translational invariants
Nicholas F. Marshall, Ti-Yen Lan, Tamir Bendory +1
We introduce a framework for recovering an image from its rotationally and translationally invariant features based on autocorrelation analysis. This work is an instance of the mul…
Randomized mixed Hölder function approximation in higher-dimensions
Nicholas F. Marshall
The purpose of this paper is to extend the result of arXiv:1810.00823 to mixed Hölder functions on for all . In particular, we prove that by sampling an -mixe…
A fast simple algorithm for computing the potential of charges on a line
Zydrunas Gimbutas, Nicholas F. Marshall, Vladimir Rokhlin
We present a fast method for evaluating expressions of the form where are…
A Cheeger inequality for graphs based on a reflection principle
Edward Gelernt, Diana Halikias, Charles Kenney +1
Given a graph with a designated set of boundary vertices, we define a new notion of a Neumann Laplace operator on a graph using a reflection principle. We show that the first eigen…
