Robust automated reading of the skin prick test via 3D imaging and parametric surface fitting
(Public Library of Science, 2019)
The conventional reading of the skin prick test (SPT) for diagnosing allergies is prone to inter- and intra-observer variations. Drawing the contours of the skin wheals from the SPT and scanning them for computer processing ...
Developing a Robust Acquisition System for Fringe Projection Profilometry
(Institute of Physics Publishing, 2019)
Since Fringe Projection Profilometry (FPP) is an intensity-based coding strategy, it is prone to improper optical setup arrangement, surface texture and reflectance, uneven illumination distribution, among others. These ...
A Structure-from-Motion Pipeline for Generating Digital Elevation Models for Surface-Runoff Analysis
(Institute of Physics Publishing, 2019)
Digital Elevation Models (DEMs) are used to derive information from the morphology of a land. The topographic attributes obtained from the DEM data allow the construction of watershed delineation useful for predicting the ...
A model for the simulation of the chill block melt spinning (CBMS) process using OpenFOAM®
(Elsevier Masson SAS, 2020)
This work shows the results of a numerical model developed to simulate the CBMS technique for the production of the Fe78Si9B13 metallic magnetic ribbons for application in electronics. The model proposes a numerical ...
A vision-based system for the dynamic measurement of in-plane displacements
(Institute of Electrical and Electronics Engineers Inc., 2014)
Computer vision has advanced markedly in the last decade and has had new applications such as the analysis of the behavior of structures. The analysis of displacement and deformation of structures is an important process ...
Experimental investigation of high-speed melt spinning by means of digital image analysis
(OSA - The Optical Society, 2016)
We carry out an experimental characterization via high-speed camera of Chill-Block Melt Spinning process by means of digital optical flow for melt ejection velocity calculation and temperature measurement. © OSA 2016.
Background intensity removal in Fourier transform profilometry: A comparative study
(OSA - The Optical Society, 2016)
We study the removal of the background intensity of fringe patterns via Empirical Mode Decomposition and the Hilbert Transform. Simulation results show that the latter provides a suitable background compensation with minimal ...
Restoration of retinal images with space-variant blur
(2014)
Retinal images are essential clinical resources for the diagnosis of retinopathy and many other ocular diseases. Because of improper acquisition conditions or inherent optical aberrations in the eye, the images are often ...
Blind restoration of retinal images degraded by space-variant blur with adaptive blur estimation
(2013)
Retinal images are often degraded with a blur that varies across the gield view. Because traditional deblurring algorithms assume the blur to be space-invariant they typically fail in the presence of space-variant blur. ...
Vehicle speed estimation using audio features and neural networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
Many car accidents that result in pedestrian deaths or serious injuries are due to their inattention when crossing the street. Pedestrians often get distracted using mobile phones or music players, what prevents them to ...
