Colour image denoising by eigenvector analysis of neighbourhood colour samples
(Springer, 2020-04)
Colour image smoothing is a challenging task
because it is necessary to appropriately distinguish between noise and original structures, and to smooth noise
conveniently. In addition, this processing must take into
account ...
Analysis of practical fractional vortex beams at far field
(Elsevier ScienceDirect, 2022-07-20)
The subject of calculating the topological charge (TC) or vortex strength of optical vortices has generated divided opinions among scientists. This is due to the fact that proper analytical results are hard to support from ...
A novel method for in-home Gait Speed estimation in Health Monitoring Using Bluetooth Low Energy
(IEEE, 2021)
Gait speed (GS) is a crucial parameter in the
evolution and diagnosis of degenerative illnesses. Nowadays, it is
measured in clinical environments where it is impossible to keep
track of all patients due to the lack of ...
Generalized Scalable Neighborhood Component Analysis for Single and Multi-Label Remote Sensing Image Characterization
(IEEE, 2021)
Deep metric learning has recently become a prominent technology for the semantic understanding ofremote sensing (RS)
scenes due to its great potential for characterizing visual semantics. However, state-of-the-art deep ...
Glimpse: A gaze-based measure of temporal salience
(Multidisciplinary Digital Publishing Institute, 2021-04-29)
Temporal salience considers how visual attention varies over time. Although visual salience
has been widely studied from a spatial perspective, its temporal dimension has been mostly ignored,
despite arguably being of ...
Femtosecond-laser-irradiation-induced structural organization and crystallinity of Bi2WO6
(Nature Research, 2020)
Controlling the structural organization and crystallinity of functional oxides is key to enhancing
their performance in technological applications. In this work, we report a strong enhancement of
the structural organization ...
Wavelet-Based Entropy Measures to Characterize Two-Dimensional Fractional Brownian Fields
(MDPI, 2020-02-07)
The aim of this work was to extend the results of Perez et al. (Physica A (2006), 365 (2), 282–288) to the two-dimensional (2D) fractional Brownian field. In particular, we defined Shannon entropy using the wavelet spectrum ...
An IoT Platform Based on Microservices and Serverless Paradigms for Smart Farming Purposes
(MDPI, 2020)
Nowadays, the concept of “Everything is connected to Everything” has spread to reach increasingly diverse scenarios, due to the benefits of constantly being able to know, in real-time, the status of your factory, your city, ...

Multimodal Sensor Data Integration for Indoor Positioning in Ambient-Assisted Living Environments
(Hindawi, 2020)
A reliable Indoor Positioning System (IPS) is a crucial part of the Ambient-Assisted Living (AAL) concept. The use of Wi-Fi fingerprinting techniques to determine the location of the user, based on the Received Signal ...
