Depth estimation improvement in 3D integral imaging using an edge removal approach
(Springer, 2018)
A new depth estimation method for 3D reconstruction in a synthetic aperture integral imaging framework is presented. This
method removes the edges of the objects in the elemental images when the objects are in focus. This ...
A distance-based model for spatial prediction using radial basis functions
(Springer Berlin Heidelberg, 2018)
In the context of local interpolators, radial basis functions (RBFs) are known to reduce the computational time by using a subset of the data for prediction purposes. In this paper, we propose a new distance-based spatial ...
Low-cost single-pixel 3D imaging by using an LED array
(Optical Society of America, 2018)
We propose a method to perform color imaging with a single photodiode by using
light structured illumination generated with a low-cost color LED array. The LED array is
used to generate a sequence of color Hadamard ...
Geospatial Analysis of Extreme Weather Events in Nigeria (1985–2015) Using Self-Organizing Maps
(2017)
The explosion of data in the information age has provided an opportunity to explore the possibility of characterizing the climate patterns using data mining techniques. Nigeria has a unique tropical climate with two ...
An Indoor Positioning System Based on Wearables for Ambient-Assisted Living
(MDPI, 2016)
The urban population is growing at such a rate that by 2050 it is estimated that 84% of the world’s population will live in cities, with flats being the most common living place. Moreover, WiFi technology is present in ...
Empleabilidad y competencias en el sector geoespacial para los profesionales del mañana
(eGeoMapping S.L., 2019)
El presente artículo reflexiona sobre la falta de profesionales en el sector europeo de la Geoinformática y Observación de la Tierra, a través del análisis de la demanda sectorial, la oferta formativa existente ...
Promoting Pollution-Free Routes in Smart Cities Using Air Quality Sensor Networks
(MDPI, 2018)
Nowadays, citizens have a huge concern about the quality of life in their cities,
especially regarding the level of pollution. Air quality level is of great importance, not only to
plan our activities but also to take ...
Generation of multifocal irradiance patterns by using complex Fresnel holograms
(Optical Society of America, 2018)
We experimentally demonstrate Fresnel holograms able to produce multifocal irradiance patterns with micrometric spatial resolution. These holograms are assessed from the coherent sum of multiple Fresnel lenses. The utilized ...
A dichotomy property for locally compact groups
(Elsevier, 2018-08)
We extend to metrizable locally compact groups Rosenthal's theorem describing those Banach spaces containing no copy of l1. For that purpose, we transfer to general locally compact groups the notion of interpolation (Io) ...
Point Patterns Occurring on Complex Structures in Space and Space-Time: An Alternative Network Approach
(Taylor & Francis, 2017-10)
This article presents an alternative approach of analyzing possibly multitype point patterns in space and space–time that occur on network structures, and it introduces several different graph-related intensity measures. ...
