Computational imaging with a balanced detector
(Nature Publishing, 2016-06-29)
Single-pixel cameras allow to obtain images in a wide range of challenging scenarios, including broad regions of the electromagnetic spectrum and through scattering media. However, there still exist several drawbacks that ...
Coherent multi-heterodyne spectroscopy using acousto-optic frequency combs
(Optical Society of America, 2018)
We propose and characterize experimentally a new source of optical frequency combs for performing multi-heterodyne spectrometry. This comb modality is based on a frequency-shifting loop seeded with a continuous-wave (CW) ...
Single-pixel imaging with Fourier filtering: application to vision through scattering media
(Optical Society of America, 2019-02-01)
We present a novel approach for imaging through scattering media that combines the principles of Fourier spatial filtering and single-pixel imaging. We compare the performance of our single-pixel imaging setup with that ...
Improving RF Fingerprinting Methods by Means of D2D Communication Protocol
(MDPI, 2019-01-16)
Radio Frequency (RF) fingerprinting is widely applied for indoor positioning due to the existing Wi-Fi infrastructure present in most indoor spaces (home, work, leisure, among others) and the widespread usage of smartphones ...
An Analytics Platform for Integrating and Computing Spatio-Temporal Metrics
(MDPI, 2019)
In large-scale context-aware applications, a central design concern is capturing, managing
and acting upon location and context data. The ability to understand the collected data and define
meaningful contextual events, ...
Adapting Models to Warn Fungal Diseases in Vineyards Using In-Field Internet of Things (IoT) Nodes
(MDPI, 2019)
Weather conditions are one of the main threats that can lead to diseases in crops. Unfavourable conditions, such as rain or high humidity, can produce a risk of fungal diseases. Meteorological monitoring is vital to have ...
Depth and All-in-Focus Image Estimation in Synthetic Aperture Integral Imaging Under Partial Occlusions
(IEEE, 2018-12)
A common assumption in the integral imaging reconstruction is that a pixel will be photo-consistent if all viewpoints observed by the different cameras converge at a single point when focusing at the proper depth. However, ...
Ranking European capitals by exposure to heat waves and cold waves
(Elsevier, 2019)
In warming Europe, we are witnessing a growth in urban population with aging trend, which willmake the society more exposed and vulnerable to extreme weather events. In the period1950–2015 the occurrence of extreme heat ...
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 ...
High-Sensitivity High-Speed Compressive Spectrometer for Raman Imaging
(American Chemical Society, 2019-04-25)
Compressive Raman is a recent framework that allows for large data compression of microspectroscopy during its measurement. Because of its inherent multiplexing architecture, it has shown imaging speeds considerably higher ...
