On the numerical solution of the linear and nonlinear Poisson equations seen as bi-dimensional inverse moment problems
(Taylor & Francis, 2016-12)
The numerical solution of the bi-dimensional nonlinear Poisson equations under Cauchy boundary conditions is considered. Using Green identity we show that this problem is equivalent to solve a bi-dimensional Fredholm ...
Descripción y análisis de forma basado en la invarianza a isometrías de los esqueletos topológicos
(Universidad Nacional de ColombiaMedellín - Minas - Doctorado en Ingeniería - SistemasDepartamento de la Computación y la DecisiónFacultad de MinasMedellínUniversidad Nacional de Colombia - Sede Medellín, 2019-06)
In this dissertation, we explore the problem of how to describe the shape of an object in 2D and 3D with a set of features that are invariant to isometric transformations. We focus to based our approach on the well-known ...
