First- and Second-Order Characteristics of Spatio-Temporal Point Processes on Linear Networks
(American Statistical AssociationInstitute of Mathematical StatisticsInterface Foundation of North AmericaTaylor and Francis, 2019-12-23)
We present several characteristics for spatio-temporal point patterns when the spatial locations are restricted to a linear network. A nonparametric kernel-based intensity estimator is proposed to highlight the concentration ...
Reliability Validation of a Low-Cost Particulate Matter IoT Sensor in Indoor and Outdoor Environments Using a Reference Sampler
(MDPI, 2019)
A suitable and quick determination of air quality allows the population to be alerted with respect to high concentrations of pollutants. Recent advances in computer science have led to the development of a high number of ...
FloU-Net: An Optical Flow Network for Multi-modal Self-Supervised Image Registration
(Institute of Electrical and Electronics Engineers, 2023)
Image registration is an essential task in image
processing, where the final objective is to geometrically align
two or more images. In remote sensing, this process allows
comparing, fusing or analyzing data, specially ...
A Generative Method for Indoor Localization Using Wi-Fi Fingerprinting
(MDPI, 2021-03-30)
Indoor localization is an enabling technology for pervasive and mobile computing applications. Although different technologies have been proposed for indoor localization, Wi-Fi fingerprinting is one of the most used ...
Fast Kernel Smoothing of Point Patterns on a Large Network using Two-dimensional Convolution
(Wiley, 2019-06)
We propose a computationally efficient and statistically principled method for kernel smoothingof point pattern data on a linear network. The point locations, and the network itself, are convolvedwith a two-dimensional ...
Curvature approximation from parabolic sectors
(International Society for Stereology, 2017)
We propose an invariant three-point curvature approximation for plane curves based on the arc of a parabolic sector, and we analyze how closely this approximation is to the true curvature of the curve. We compare our results ...
In-home monitoring system based on WiFi fingerprints for ambient assisted living
(IOS, 2017-08)
This paper presents an in-home monitoring system based on WiFi fingerprints for Ambient Assisted Living. WiFi fingerprints are used to continuously locate a patient at the different rooms in her/his home. The experiments ...
Deployment of an open sensorized platform in a smart city context
(Elsevier, 2017-11)
The race to achieve smart cities is producing a continuous effort to adapt new developments and knowledge, for administrations and citizens. Information and Communications Technology are called on to be one of the key ...
Real-time acquisition of complex optical fields by binary amplitude modulation
(Optical Society of America, 2017)
We describe, through simulations and experiments, a real-time wavefront acquisition technique using random binary amplitude masks and an iterative phase retrieval algorithm based on the Fresnel propagator. By using a digital ...
Integral imaging techniques for flexible sensing through image-based reprojection
(OSA Publishing, 2017-10)
In this work, a 3D reconstruction approach for flexible sensing inspired by integral imaging techniques is proposed. This method allows the application of different integral imaging techniques, such as generating a depth ...
