A continuous analog for 4-dimensional objects
Pacheco Martínez, Ana María; Mari, Jean-Luc; Real Jurado, Pedro (2013)In this paper, we follow up on the studies developed by Kovalevsky (Comput Vis Graph Image Process 46:141–161, 1989) and ...

Allowing cycles in discrete Morse theory
González Lorenzo, Aldo; Bac, Alexandra; Mari, Jean-Luc; Real Jurado, Pedro (Elsevier, 2017)Discrete gradient vector fields are combinatorial structures that can be used for accelerating the homology computation ...

Cellular Skeletons: A New Approach to Topological Skeletons with Geometric Features
González Lorenzo, Aldo; Bac, Alexandra; Mari, Jean-Luc; Real Jurado, Pedro (2015)This paper introduces a new kind of skeleton for binary volumes called the cellular skeleton. This skeleton is not a subset ...

Computational Homology Applied to Discrete Objects
González Lorenzo, Aldo (2016-11-24)Homology theory formalizes the concept of hole in a space. For a given subset of the Euclidean space, we define a sequence ...

Computing Homological Information Based on Directed Graphs within Discrete Objects
González Lorenzo, Aldo; Bac, Alexandra; Mari, Jean-Luc; Real Jurado, Pedro (IEEE Computer Society, 2014)n-dimensional discrete objects can be interpreted as cubical complexes which are suitable for the study of their homology ...

Fast, Simple and Separable Computation of Betti Numbers on Three-dimensional Cubical Complexes
González Lorenzo, Aldo; Juda, Mateusz; Bac, Alexandra; Mari, Jean-Luc; Real Jurado, Pedro (Springer, 2016)Betti numbers are topological invariants that count the number of holes of each dimension in a space. Cubical complexes ...

Obtaining cell complexes associated to four dimensional digital objects
Pacheco Martínez, Ana María; Mari, Jean-Luc; Real Jurado, Pedro (Universidad de Sevilla, 2010)In this paper, we determine a cell complex representation of a 80–adjacent doxelbased 4-dimensional object. The homological ...

Topological Comparisons of Fluvial Reservoir Rock Volumes Using Betti Numbers: Application to CO2 Storage Uncertainty Analysis
Dahrabou, Asmae; Viseur, Sophie; González Lorenzo, Aldo; Rohmer, Jérémy; Bac, Alexandra; Real Jurado, Pedro; Mari, Jean-Luc; Audigane, Pascal (Springer, 2016)To prevent the release of large quantities of CO2 into the atmosphere, carbon capture and storage (CCS) represents a ...

Two Measures for the Homology Groups of Binary Volumes
González Lorenzo, Aldo; Bac, Alexandra; Mari, Jean-Luc; Real Jurado, Pedro (Springer, 2016)Given a binary object (2D or 3D), its Betti numbers characterize the number of holes in each dimension. They are obtained ...
