A new approach to occupancy map modeling in navigation assisted by computer vision

Riquelme Madrona, Julio; Ortigosa, Nuria; Magal Royo, Teresa; Morillas, Samuel; Peris Fajarnes, Guillermo (2011)

[EN] Occupancy grid maps have been widely used in robotics for navigation assistance. Most of the current occupancy maps use grids based on Cartesian coordinates. In this paper, we introduce a new approach to occupancy map ...
Atrial fibrillation subtypes classification using the General Fourier-family Transform

Ortigosa, Nuria; Cano, O.; Ayala Gallego, Guillermo; Galbis Verdu, Antonio; Fernandez Rosell, Carmen (Elsevier, 2014-04)

Atrial fibrillation patients can be classified into paroxysmal, persistent and permanent attending to the temporal pattern of this arrhythmia. The surface electrocardiogram hides this differentiation. A classification ...
Detección de caminos libres de obstáculos mediante mapas de profundidad

Ortigosa Araque, Nuria (Universitat Politècnica de València, 2011-11-24)

[ES] El procesado del espacio libre presente en la escena es básico para el correcto funcionamiento de muchas aplicaciones en el ámbito de la robótica y de la navegación. En este trabajo se presenta un método para ...
Early prediction of cardiac resynchronization therapy response by non-invasive electrocardiogram markers

Ortigosa, Nuria; Pérez-Roselló, Víctor; Donoso, Victor; Osca Asensi, Joaquín; Martínez-Dolz, Luis; Fernández Rosell, Carmen; Galbis Verdu, Antonio (Springer-Verlag, 2018-04)

[EN] Cardiac resynchronization therapy (CRT) is an effective treatment for those patients with severe heart failure. Regrettably, there are about one third of CRT "non-responders", i.e. patients who have undergone this ...
Estudio sobre transformadas tiempo-frecuencia aplicables al análisis de electrocardiogramas. Desarrollo de una aplicación con Guide de Matlab para la obtención de señales de electrocardiogramas en formato PDF

Giménez Solano, Vicente Miguel (Universitat Politècnica de València, 2014-11-25)

[EN] In this paper we analyze a particular type of biomedical signals: the electrocardiogram (ECG). To analyze these signals, a very powerful digital processing technique are time-frequency transforms. With them, ECG leads ...
Fuzzy Free Path Detection based on Dense Disparity Maps obtained from Stereo Cameras

Ortigosa Araque, Nuria; Morillas Gómez, Samuel; Peris Fajarnes, Guillermo; Dunai Dunai, Larisa (World Scientific Publishing, 2012-04)

In this paper we propose a fuzzy method to detect free paths in real-time using digital stereo images. It is based on looking for linear variations of depth in disparity maps, which are obtained by processing a pair of ...
Fuzzy Free Path Detection from Disparity Maps by Using Least-Squares Fitting to a Plane

Ortigosa Araque, Nuria; Morillas Gómez, Samuel (Springer Verlag (Germany), 2014-08)

A method to detect obstacle-free paths in real-time which works as part of a cognitive navigation aid system for visually impaired people is proposed. It is based on the analysis of disparity maps obtained from a stereo ...
Gabor frames for classification of paroxysmal and persistent atrial fibrillation episodes

Ortigosa, Nuria; Galbis Verdu, Antonio; Fernández, Carmen; Cano-Pérez, Óscar (Elsevier, 2017-01)

[EN] In this study, we propose a new classification method for early differentiation of paroxysmal and persistent atrial fibrillation episodes, i.e. those which spontaneously or with external intervention will return to ...
Heart morphology differences induced by intrauterine growth restriction and preterm birth measured on the ECG at preadolescent age

Ortigosa, Nuria; Rodriguez-Lopez, Merida; Bailón, Raquel; Sarvari, Sebastian Imre; Sitges, Marta; Gratacos, Eduard; Bijnens, Bart; Crispi, Fatima; Laguna, Pablo (Elsevier, 2016-06)

[EN] Intrauterine Growth Restriction (IUGR) and premature birth are associated with higher risk of cardiovascular diseases throughout adulthood. The aim of this study was to evaluate the influence of these factors in ...
Modding de equipos informáticos como herramienta de aprendizaje en áreas STEM

Rodríguez Ruiz, Alberto; Ortigosa Araque, Nuria (Editorial Universitat Politècnica de València, 2019-05-07)

[◄ES] El empleo de actividades que permitan mantener activo el interés al alumnado en distintas materias es un instrumento fundamental para mejorar el aprendizaje y ampliar conocimientos en todas las áreas educativas. ...
Modelado y análisis de datos procedentes de sistemas de imagen para diagnóstico médico mediante Mathematica

Ortigosa, Nuria; Cerdá Boluda, Joaquín (Universitat Politècnica de València, 2017-01-31)

[EN] Modelling in Science Education and Learninghttp://polipapers.upv.es/index.php/MSELMSELModellingin Science Education and LearningModelling in Science Education and LearningVolume 10 (1), 2017doi: 10.4995/msel.2017.66 ...
Primera experiencia y presentación de labores investigadoras referentes a análisis de imágenes médicas para alumnos de enseñanzas medias

Ortigosa, Nuria; Cerdá Boluda, Joaquín (Editorial Universitat Politècnica de València, 2019-05-07)

[ES] Los Campus Científicos de Verano tienen como objetivo que los alumnos de enseñanzas medias de las opciones científico-técnicas tengan un primer contacto con la labor investigadora que se realiza en las universidades ...
