FACe! 3D Facial Animation System based on FACS
(2009-06)In this paper we present a 3D facial animation system named FACe! It is able to generate different expressions of the face throughout punctual and combined activation of Action Units, defined by Facial ... -
Narrowband and Wideband Channel Sounding of an Antarctica to Spain Ionospheric Radio Link
(2015-06)La Salle and Ebro Observatory have been involved in several joint projects about remote sensing in Antarctica for the last 11 years (approximately one solar cycle). The Ebro Observatory has been monitoring ... -
Conceptualizing Energy performance-based Design: a case of social housing
(2013-09)Over the past three decades, performance-based design has pursued the development of a methodology that anticipates the impact of a design solution in order to evaluate ... -
Optimistic concurrency control with partial replication design
(2009-11)This paper presents a performance comparison of optimistic concurrency control algorithms using a database design with partial replication. Most studies always assume total replication design, but this ... -
Dynamic Distributed Storage Architecture on Smart Grids
(2011-07)Most of the power network services such as voltage control, asset management, or flow monitoring are implemented within a centralized paradigm. Novel distributed power generation techniques—eolian fields ... -
Local minimum generation error criterion for hybrid HMM speech synthesis
(2009-09)This paper presents an HMM-driven hybrid speech synthesis approach in which unit selection concatenative synthesis is used to improve the quality of the statistical system using a Local Minimum Generation ... -
Códigos QR aplicados a la visualización de elementos arquitectónicos
(2011-11)In recent years it has popularized the use of two-dimensional codes associated with all types of information. Usually we can find them in advertisements, receipts and all kinds of tickets, but also they ... -
Decision Support System for the Breast Cancer Diagnosis by a Meta-learning Approach based on Grammar Evolution
(2006-05)The incidence of breast cancer varies greatly among countries, but statistics show that every year 720,000 new cases will be diagnosed world-wide. However, a low percentage of women who suffer it can ... -
Cultural values influence on the adoption of privacy threatening social networks features
(2010-04)The effect of cultural values in IT adoption has attracted growing interest in the last years. Researchers posit that cultural values can shed some additional light on the factors that determine IT user ... -
Aplicación docente de Realidad Aumentada en cursos universitarios de representación de proyectos de Arquitectura. Case study of application of augmented reality in university courses for representation of projects of architecture
(2011-11)The purpose of the work is to define and evaluate a method for the application of 3D rendering techniques with augmented reality in architectural courses and graphic representation. This will allow ... -
Objective Viseme Extraction and Audiovisual Uncertainty: Estimation Limits between Auditory and Visual Modes
(2007-08)An objective way to obtain consonant visemes for any given Spanish speaking person is proposed. Its face is recorded while speaking a balanced set of sentences and stored as an audiovisual sequence. ... -
Análisis y Síntesis Audiovisual para Interfaces Multimodales Ordenador-Persona
(2006-11)Las técnicas multimodales de procesamiento de señal están llamadas a jugar un papel preponderante en la implementación de interfaces que faciliten la interacción natural entre los ordenadores y los ... -
Analyzing Active Interactive Genetic Algorithms using Visual Analytics
(Proceedings of the 8th annual conference on Genetic and evolutionary computation, 2006, 2006-07)This paper builds introduces visual-analytic techniques to aggregate, summarize, and visualize the information generated during interactive evolutionary processes. Special visualizations of the user-provided ... -
Feature Diversity in Cluster Ensembles for Robust Document Clustering
(2006-08)The performance of document clustering systems depends on employing optimal text representations, which are not only difficult to determine beforehand, but also may vary from one clustering problem to ... -
Revisión sobre métricas de complejidad en el modelado de clústers de un sistema CBR
(2007-09)El análisis de la complejidad de los datos mediante métricas de complejidad es útil para predecir el comportamiento de un sistema de aprendizaje. Este trabajo ilustra cómo las métricas permiten definir ... -
Linguistic and Mixed Excitation Improvements on a HMM-based speech synthesis for Castilian Spanish
(Proceedings of the 6th ISCA Workshop on Speech Synthesis, 2007-08)HiddenMarkov Models based text-to-speech(HMM-TTS)synthesis is one of the techniques for generating speech from trained statistical models where spectrum and prosody of basic speech units are modelled ... -
Two Strategies on Border Labeling applied to the Estimation of Ejection Fraction
(2004-06)As we have already presented in previous conferences, our algorithm uses SPECT data to automatically recover the three-dimensional shape of the human's left ventricle. The reconstruction of both the ... -
Left ventricle's surface reconstruction and volume estimation
(2002-06)This document describes the three-dimensional reconstruction of the internal and external surfaces of the human’s left ventricle from actual SPECT data. The reconstruction is a first process fitting in ... -
