Retinal verification using a feature points-based biometric pattern
(Springer, 2009)Biometrics refer to identity verification of individuals based on some physiologic or behavioural characteristics. The typical authentication process of a person consists in extracting a biometric pattern of him/her and ... -
CNN technology for spatiotemporal signal processing
(Springer, 2009) -
Performance analysis of massively parallel embedded hardware architectures for retinal image processing
(Springer, 2011)This paper examines the implementation of a retinal vessel tree extraction technique on different hardware platforms and architectures. Retinal vessel tree extraction is a representative application of those found in the ... -
Spin-polarized transport in a full magnetic pn tunnel junction
(AIP Publishing, 2011)Simulations of the tunneling current as a function of voltage and temperature for a Zener diode where both sides are ferromagnetic have been performed. The current is evaluated as a function of the applied bias, the ... -
Density functional study of the magnetic properties of Bi4Mn clusters: Discrepancy between theory and experiment
(AIP Publishing, 2011)We have performed collinear and noncollinear calculations on neutral Bi4Mn and collinear ones on ionized Bi4Mn with charges +1 and −1 to find out why theoretical calculations will not predict the magnetic state found in ... -
Estrategias de sostenibilidad y responsabilidad social en las universidades españolas: una herramienta para su evaluación
(Universidad de Granada. Facultad de Ciencias de la Educación, 2012) -
Learning in real robots from environment interaction
(Universitat d'Alacant, 2012)This article describes a proposal to achieve fast robot learning from its interaction with the environment. Our proposal will be suitable for continuous learning procedures as it tries to limit the instability that appears ... -
Exploración en tiempo real de la reconstrucción virtual de los instrumentos del Pórtico de la Gloria
(Universitat Politècnica de València, 2012)En este artículo se presenta el desarrollo de un sistema para la visualización interactiva de la reconstrucción virtual de los instrumentos del Pórtico de la Gloria. Se explica el proceso seguido para la creación de un ... -
Virtual Reality as a Tool for Evaluation of Repetitive Rhythmic Movements in the Elderly and Parkinson's Disease Patients
(PLOS, 2012)This work presents an immersive Virtual Reality (VR) system to evaluate, and potentially treat, the alterations in rhythmic hand movements seen in Parkinson's disease (PD) and the elderly (EC), by comparison with healthy ... -
Multi-agent system for fast deployment of a guide robot in unknown environments
(Universitat d'Alacant, 2012)Nowadays, deploying service robots and adapting their services to a new environment is a task which might require several days. This is an important problem of robotics in general, but specially when the goal is to bring ... -
Automatic detection of pulmonary nodules: Evaluation of performance using two different MDCT scanners
(Sciedu Press, 2012)The purpose of this study was to evaluate the diagnostic performance of a computer-aided diagnosis (CAD) system, on the detection of pulmonary nodules in multidetector row computed tomography (MDCT) images, by using two ... -
Statistical comparison of classifiers applied to the interferential tear film lipid layer automatic classification
(Hindawi, 2012)The tear film lipid layer is heterogeneous among the population. Its classification depends on its thickness and can be done using the interference pattern categories proposed by Guillon. The interference phenomena can be ... -
On the relationship between optical variability, visual saliency, and eye fixations: a computational approach
(Association for Research in Vision and Ophthalmology, 2012)A hierarchical definition of optical variability is proposed that links physical magnitudes to visual saliency and yields a more reductionist interpretation than previous approaches. This definition is shown to be grounded ... -
Querying phenotype-genotype relationships on patient datasets using semantic web technology: the example of cerebrotendinous xanthomatosis
(BMC, 2012)Background: Semantic Web technology can considerably catalyze translational genetics and genomics research in medicine, where the interchange of information between basic research and clinical levels becomes crucial. This ... -
Conocimiento tecnológico-didáctico del contenido en la enseñanza de Ingeniería Informática: un estudio de caso colaborativo con la perspectiva del docente y los investigadores
(Universitat Politècnica de València, 2013)Este trabajo tiene como marco un proyecto de investigación coordinado entre tres universidades (Barcelona, Sevilla y Santiago de Compostela) titulado: El conocimiento profesional del profesor universitario: procesos de ... -
Self-Organized Multi-Camera Network for a Fast and Easy Deployment of Ubiquitous Robots in Unknown Environments
(MDPI, 2013)To bring cutting edge robotics from research centres to social environments, the robotics community must start providing affordable solutions: the costs must be reduced and the quality and usefulness of the robot services ... -
A FastSLAM-based Algorithm for Omnidirectional Cameras
(Universitat d'Alacant, 2013)Environments with a low density of landmarks are difficult for vision-based Simultaneous Localization and Mapping (SLAM) algorithms. The use of omnidirectional cameras, which have a wide field of view, is specially interesting ... -
Multiresolution rendering based on GPGPU computing
(Research Institute of Intelligent Computer Systems, 2013)The problem of visualizing large volumetric datasets is appealing for computation on the GPU. Nevertheless, the design of GPU volume rendering solutions must deal with the limited available memory in a graphics card. In ... -
Learning on real robots from experience and simple user feedback
(Universitat d'Alacant, 2013)In this article we describe a novel algorithm that allows fast and continuous learning on a physical robot working in a real environment. The learning process is never stopped and new knowledge gained from robot-environment ... -
