A Velocity Estimation Technique for a Monocular Camera Using mmWave FMCW Radars
2021
Perception in terms of object detection, classification, and dynamic estimation (position and velocity) are fundamental functionalities that autonomous agents (unmanned ground vehicles, unmanned aerial vehicles, or robots) have to navigate safely and autonomously. To date, various sensors have been used individually or in combination to achieve this goal. In this paper, we present a novel method for leveraging millimeter wave radar’s (mmW radar’s) ability to accurately measure position and velocity in order to improve and optimize velocity estimation using a monocular camera (using optical flow) and machine learning techniques. The proposed method eliminates ambiguity in optical flow veloci…
Estereotipos asociados al cuerpo humano: análisis de aplicaciones móviles usadas en la educación físico-deportiva
2022
Institutions and educators are massively and uncritically integrating digital curricular materials in their teaching praxis. This article aims to uncover whether health and fitness APP images convey or legitimize stereotypes linked to bodies, focusing on gender, race, somatotype and physical activity practice. We also analyse whether these apps are adequate for the recommended age or whether they are designed by physical education professionals. For that purpose, we designed a descriptive, comparative study based on content analysis on a sample of 373 images from 128 apps selected through a PRISMA review and a pilot test. Our results report that bodies reproduce a series of stereotypes: of …
An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety
2017
In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…

Simafield : Un logiciel de modélisation spatiale de scènes agronomiques
2013
Environmental measures lead farmers to use more and more decision support tools to reduce their chemical inputs without losing yield. Imaging system based on crop/weed discrimination algorithms have been developed to detect weeds in field and allow a site specific spraying. These algorithms needs to be thoroughly evaluated before considering a public release and current evaluation are based on real images and are very tedious. SimAField is a software that aims at modeling agronomic fields with crop and weeds and simulate the picture taking process to replace ground truth and allow an automated evaluation of crop/weed discrimination algorithms.
Applicazioni dell’image processing nel campo delle infrastrutture viarie. il caso della viabilità in esercizio
2010
Nel settore delle infrastrutture di trasporto, si stanno sempre più sviluppando specifiche tecniche di rilievo automatico, ad alto rendimento, utilizzate per il monitoraggio dei parametrici caratteristici del traffico e di quelli geometrici dell’infrastruttura. Di particolare interesse per la loro semplicità, flessibilità d’uso, economia ed affidabilità sono le tecniche basate sull’image processing, che prevedono l’impiego sinergico di un sistema di monitoraggio e di elaborazione delle sequenze video registrate con strumentazioni digitali o analogiche. In questo ambito, le molteplici esperienze di ricerca già maturate hanno dimostrato la versatilità di tali procedure in numerose applicazion…

Motility analysis by means of video tracked markers
2018
Abstract The motility of the gastrointestinal tract is crucial for digestive activity and dysfunction can lead to severe disease pattern. A method for analysing the motility is needed when treatment approaches shall be evaluated. Therefore markers attached to different locations on the stomach and the bowel of pigs are video tracked in this research study. The markers are designed to provide a high contrast and have an adhesive side for fixation. Above the operation field a video camera has been placed to film the markers during the procedure. To analyse the video data a special algorithm has been implemented. The algorithm requires a registration process at the beginning of each recording …
Sports as a motivation to study English : young athletes and the L2 motivational self system
2013
Tutkimuksen lähtökohtana oli Zoltán Dörnyein uusi motivaatioteoria, joka koostuu oppijoiden tulevaisuuden minäkuvista sekä aiemmista kokemuksista kohdekieleen liittyen. Kyseistä teoriaa ei ole vielä laajalti käytetty tutkimuksessa, ja suomalaiset kieltenoppijat ovat vielä varsin uusi kohderyhmä kyseiselle teorialle. Tutkimuksen tarkoituksena oli selvittää nuorten urheilijoiden suhtautumista englantiin ja sen tärkeyteen. Tutkimuksessa tutkittiin urheilijoiden 1) yleisiä asenteita englantia kohtaan, 2) heidän urheiluun ja englantiin liittyviä tulevaisuuden minäkuvia, sekä 3) heidän aiempia urheiluun liittyviä kokemuksia englannin käytöstä. Urheilijat ovat uusi kohderyhmä motivaatiotutkimukses…
