Toward Parallel Computation of Dense Homotopy Skeletons for nD Digital Objects
(Springer, 2017)
An appropriate generalization of the classical notion of abstract cell complex, called primal-dual abstract cell complex (pACC for short) is the combinatorial notion used here for modeling and analyzing the topology of ...

SIRIUS: Improving the maneuverability of powered wheelchairs
(IEEE Computer Society, 2002)
The indoor maneuverability of powered wheelchairs may be difficult or bothersome in several circumstances. In this paper, we describe an experimental powered wheelchair named SIRIUS, developed at the University of Seville, ...

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 ...

Mobile robot motion planning based on cloud computing stereo vision processing
(IEEE Computer Society, 2014)
Nowadays, the limitations of robot embedded hardware (which cannot be upgraded easily) make difficult to perform computationally complex tasks such as those of high level artificial vision. However, instead of disposing ...

The shared control dynamic window approach for non-holonomic semi-autonomous robots
(IEEE Computer Society, 2014)
A shared control method, called Shared Control Dynamic Window Approach, is presented. It is inspired in the Dynamic Window Approach (DWA) for autonomous mobile robots. It takes user commands by means of the control interface ...

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 parametric formulation of tracking methods: application to chained systems
(IEEE Computer Society, 2004)
When following a path, there are several possibilities attending to the way in which the actual robot state can be related with the whole path. In this work, we formulate different tracking methods on the base that a ...

Performance analysis of single-slave Bluetooth piconets under cochannel interference
(IEEE Computer Society, 2004)
We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are ...
