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) ...

Multi-stage Biomarker Models for Progression Estimation in Alzheimer’s Disease
(Springer, 2015)
The estimation of disease progression in Alzheimer’s disease (AD) based on a vector of quantitative biomarkers is of high interest to clinicians, patients, and biomedical researchers alike. In this work, quantile ...

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 ...

Advanced homology computation of digital volumes via cell complexes
(2008)
Given a 3D binary voxel-based digital object V, an algorithm for computing homological information for V via a polyhedral cell complex is designed. By homological information we understand not only Betti numbers, representative ...

Open Issues and Chances for Topological Pyramids
(PRIP, Vienna University of Technology, 2009)
High resolution image data require a huge amount of computational resources. Image pyramids have shown high performance and flexibility to reduce the amount of data while preserving the most relevant pieces of information, ...

Homological tree-based strategies for image analysis
(2009)
Homological characteristics of digital objects can be obtained in a straightforward manner computing an algebraic map φ over a finite cell complex K (with coefficients in the finite field F2={0,1}) which represents the ...

Integral operators for computing homology generators at any dimension
(2008)
Starting from an nD geometrical object, a cellular subdivision of such an object provides an algebraic counterpart from which homology information can be computed. In this paper, we develop a process to drastically reduce ...

An altered microbiota pattern precedes Type 2 diabetes mellitus development: From the CORDIOPREV study
(Elsevier, 2021)
Introduction A distinctive gut microbiome have been linked to type 2 diabetes mellitus (T2DM). We aimed to evaluate whether gut microbiota composition, in addition to clinical biomarkers, could improve the prediction of ...

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 ...
