On the computability of the p-local homology of twisted cartesian products of Eilenberg-Mac Lane spaces
(Universidade do Minho, 1997)
Working in the framework of the Simplicial Topology, a method for calculating the p-local homology of a twisted cartesian product X( , m, , 0, n) = K( ,m)× K( 0, n) of Eilenberg-Mac Lane spaces is given. The chief ...

Space-Variant Gabor Decomposition for Filtering 3D Medical Images
(Springer, 2017)
This is an experimental paper in which we introduce the possibility to analyze and to synthesize 3D medical images by using multivariate Gabor frames with Gaussian windows. Our purpose is to apply a space-variant filter-like ...

Obtaining Homology Groups in Binary 2D Images Using P Systems
(IEEE Computer Society, 2009)
Membrane Computing is a new paradigms inspired from cellular communication. We use in this paper the computational devices called P systems to calculate in a general maximally parallel manner the homology groups of ...

Enhanced Parallel Generation of Tree Structures for the Recognition of 3D Images
(Springer, 2019)
Segmentations of a digital object based on a connectivity criterion at n-xel or sub-n-xel level are useful tools in image topological analysis and recognition. Working with cell complex analogous of digital objects, an ...

Generating Second Order (Co)homological Information within AT-Model Context
(Springer, 2019)
In this paper we design a new family of relations between (co)homology classes, working with coefficients in a field and starting from an AT-model (Algebraic Topological Model) AT(C) of a finite cell complex C These ...

A Cellular Way to Obtain Homology Groups in Binary 2D Images
(Fénix Editora, 2010)
In this paper we present a P systems-based solution for the Homology Groups of Binary 2D Image (HGB2I) Problem, a classical problem in Homology Theory. To this aim, we present a family of P systems which solves all the ...

Homological perturbation theory and computability of Hochschild and cyclic homologies of CDGAs
(Diffiety Institute of the Russian Academy of Natural Sciences, 1997)
We establish an algorithm computing the homology of commutative differential graded algebras (briefly, CDGAs). The main tool in this approach is given by the Homological Perturbation Theory particularized for the algebra ...

Topological Homogeneity for Electron Microscopy Images
(Springer, 2019)
In this paper, the concept of homogeneity is defined, from a topological perspective, in order to analyze how uniform is the material composition in 2D electron microscopy images. Topological multiresolution parameters ...
