From a Home-Area-Network to a Secure Internet of Things Application
(Springer, 2019)
In this paper, we present a secure system to control devices at home through the web, which we implement based on the Do It Yourself (DIY) culture. We use a model based on the Goal Question Metric approach to evaluate the ...
Camera-projector calibration methods with compensation of geometric distortions in fringe projection profilometry: A comparative study
(Sociedad Espanola de Optica, 2018)
The calibration methods most used in fringe projection profilometry are based on models of least squares adjustment and stereo vision techniques. However, the geometric distortions of the projector and camera lenses introduce ...
Dust particle artifact detection and removal in retinal images
(Sociedad Espanola de Optica, 2017)
Retinal fundus cameras suffer from dust particles attaching to the sensor and lens, which manifest as small artifacts on the images. We propose a new strategy for the detection and removal of dust particle artifacts in ...
Fringe quality map for fringe projection profilometry in LabVIEW
(Sociedad Espanola de Optica, 2018)
The phase retrieval process is mainly affected by local shadows, irregular surface brightness and fringe discontinuities. To overcome these problems, image-processing strategies are carried out such as binary masks, ...
Kinematic parameter estimation using close range photogrammetry for sport applications
(SPIE, 2015)
In this article, we show the development of a low-cost hardware/software system based on close range photogrammetry to track the movement of a person performing weightlifting. The goal is to reduce the costs to the trainers ...
Texture Analysis of Ultrasound Images for Pneumonia Detection in Pediatric Patients
(Institute of Electrical and Electronics Engineers Inc., 2019)
Pneumonia is a condition that can be life-threatening and affects a high number of children around the world. Lung ultrasound can be used for the diagnosis of pneumonia, but requires high experience. This paper presents ...
A static axisymmetric exact solution of f(R)-gravity
(2013)
We present an exact, axially symmetric, static, vacuum solution for f(R)-gravity in Weyl's canonical coordinates. We obtain a general explicit expression for the dependence of df(R)/dR upon the r and z coordinates and then ...
Overlap and diversity in antimicrobial peptide databases: Compiling a non-redundant set of sequences
(Oxford University Press, 2015)
Motivation: The large variety of antimicrobial peptide (AMP) databases developed to date are characterized by a substantial overlap of data and similarity of sequences. Our goals are to analyze the levels of redundancy for ...
Leveraging 1-wire communication bus system for secure home automation
(Springer Verlag, 2017)
Home automation is a rising technology that is available to anyone thanks to the reduce cost of the embedded systems. Since the appearance of different products to create your own domotic system, and the recent popularity ...
A structure-from-motion pipeline for topographic reconstructions using unmanned aerial vehicles and open source software
(Springer Verlag, 2018)
In recent years, the generation of accurate topographic reconstructions has found applications ranging from geomorphic sciences to remote sensing and urban planning, among others. The production of high resolution, ...
