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 ...

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 ...

A Parallel Implementation for Computing the Region-Adjacency-Tree of a Segmentation of a 2D Digital Image
(Springer, 2015)
A design and implementation of a parallel algorithm for computing the Region-Adjacency Tree of a given segmentation of a 2D digital image is given. The technique is based on a suitable distributed use of the algorithm ...

Homological Region Adjacency Tree for a 3D Binary Digital Image via HSF Model
(Springer, 2019)
Given a 3D binary digital image I, we define and compute an edge-weighted tree, called Homological Region Tree (or Hom-Tree, for short). It coincides, as unweighted graph, with the classical Region Adjacency Tree of ...

Building Hierarchical Tree Representations Using Homological-Based Tools
(Springer, 2021)
A new algorithm for computing the α-tree hierarchical repre sentation of a grey-scale digital image is presented here. The technique is based on an efficient simplified version of the Homological Spanning For est (HSF) ...

Parallel Image Processing Using a Pure Topological Framework
(Universidad de Extremadura, 2016)
Image processing is a fundamental operation in many real time applications, where lots of parallelism can be extracted. Segmenting the image into different connected components is the most known operations, but there ...

Computing the Component-Labeling and the Adjacency Tree of a Binary Digital Image in Near Logarithmic-Time
(Springer, 2019)
Connected component labeling (CCL) of binary images is one of the fundamental operations in real time applications. The adjacency tree (AdjT) of the connected components offers a region-based representation where each ...

On the Topological Disparity Characterization of Square-Pixel Binary Image Data by a Labeled Bipartite Graph
(Springer, 2022)
Given an nD digital image I based on cubical n-xel, to fully characterize the degree of internal topological dissimilarity existing in I when using different adjacency relations (mainly, comparing 2n or 2n −1 adjacency ...

A parallel Homological Spanning Forest framework for 2D topological image analysis
(Elsevier, 2016)
In [14], a topologically consistent framework to support parallel topological analysis and recognition for2 D digital objects was introduced. Based on this theoretical work, we focus on the problem of findingefficient ...
