Gait-based gender classification using persistent homology
(2013)
In this paper, a topological approach for gait-based gender recognition is presented. First, a stack of human silhouettes, extracted by background subtraction and thresholding, were glued through their gravity centers, ...

A bio-inspired software for segmenting digital images.
(2010)
Segmentation in computer vision refers to the process of partitioning a digital image into multiple segments (sets of pixels). It has several features which make it suitable for techniques inspired by nature. It can be ...

Towards the Use of Hypergraphs in Multi-adjoint Logic Programming
(Springer, 2019)
The representation of a logic program by a graph is a useful procedure in order to obtain interesting properties of the program and in the computation of the least model, when it exists. In this paper, we consider ...

Towards Minimal Barcodes
(2013)
In the setting of persistent homology computation, a useful tool is the persistence barcode representation in which pairs of birth and death times of homology classes are encoded in the form of intervals. Starting from a ...

Rescheduling Railway Timetables in Presence of Passenger Transfers Between Lines Within a Transportation Network
(Springer, 2014)
The problem of coordinating transfers consists of determining timetables which ensure the transfer of passengers between trains from different line runs at interchange stations. Two strategies can be considered: (1) Forcing ...

A homological–based description of subdivided nD objects
(2011)
We present here a topo–geometrical description of a subdivided nD object called homological spanning forest representation. This representation is a convenient tool in order to completely control not only geometrical, but ...

Existence of global weak solutions for a viscous 2D bilayer Shallow Water model
(Elsevier, 2011)
We consider a system composed by two immiscible fluids in two-dimensional space that can be modelized by a bilayer Shallow Water equations with extra friction terms and capillary effects. We give an existence theorem of ...

LBP and irregular graph pyramids
(2015)
In this paper, a new codification of Local Binary Patterns (LBP) is given using graph pyramids. The LBP code characterizes the topological category (local max, min, slope, saddle) of the gray level landscape around the ...

Incremental-Decremental Algorithm for Computing AT-Models and Persistent Homology
(2011)
In this paper, we establish a correspondence between the incremental algorithm for computing AT-models [8,9] and the one for computing persistent homology [6,14,15]. We also present a decremental algorithm for computing ...

Theoretical progress on infinite graphs and their average degree: applicability to the European Road Transport Network
(IEEE Computer Society, 2015)
There are many problems in Graph Theory for finite graphs relating the number of vertices and the number of edges and, therefore, related to the average degree for finite graphs. However, when dealing with real-life ...
