A Tool for Integer Homology Computation: Lambda-At Model
Rocio Gonzalez-Diaz, Maria Jose Jimenez, Belen Medrano +1
In this paper, we formalize the notion of lambda-AT-model (where is a non-null integer) for a given chain complex, which allows the computation of homological information in th…
On the Cohomology of 3D Digital Images
Rocio Gonzalez-Diaz, Pedro Real
We propose a method for computing the cohomology ring of three--dimensional (3D) digital binary-valued pictures. We obtain the cohomology ring of a 3D digital binary--valued pictur…
Cubical Cohomology Ring of 3D Photographs
Rocio Gonzalez-Diaz, Maria Jose Jimenez, Belen Medrano
Cohomology and cohomology ring of three-dimensional (3D) objects are topological invariants that characterize holes and their relations. Cohomology ring has been traditionally comp…
Invariant Representative Cocycles of Cohomology Generators using Irregular Graph Pyramids
Rocio Gonzalez-Diaz, Adrian Ion, Mabel Iglesias-Ham +1
Structural pattern recognition describes and classifies data based on the relationships of features and parts. Topological invariants, like the Euler number, characterize the struc…
