Abstract | En esta comunicación presentamos una experiencia en Aprendizaje Basado en Proyectos (Project
Based Learning – PBL) realizada los últimos cuatro años (cursos del 2004-05 al 2007-08) en Gráficos por Computador 2, asignatura optativa de tercer curso de Ingeniería Informática, titulación impartida en la Escuela Técnica Superior de Ingeniería (ETSE) de la Universidad Autónoma de Barcelona (UAB). Fruto de la constante voluntad de mejora de la organización ABP de nuestra asignatura nos decidimos a utilizar una herramienta LMS (Learning Management System) basada en Moodle y adaptada por nosotros llamada Caronte para poder gestionar la documentación generada en ABP, y añadir una componente semipresencial a la asignatura. En primer lugar se presenta la organización de nuestra asignatura, basada proponer al alumno dos itinerarios para cursarla: el itinerario ABP y el itinerario basado en clases magistrales i examen que llamaremos TPPE (Teoría, Problemas, Prácticas, Examen). La dinámica ABP nos genera una cantidad importante de documentación entre los grupos y el profesor, aparte de el feedback que el profesor genera a los alumnos. En la segunda parte del artículo presentamos los espacios docentes electrónicos de ambos itinerarios, con los que trabajan los alumnos. Finalmente, mostramos los resultados obtenidos de alumnos matriculados y de encuestas de valoración realizados por los alumnos para finalmente exponer las conclusiones de estos cuatro años de experiencia en ABP y en el uso de recursos virtuales en ABP, así como plantear mejoras y temas de discusión sobre ABP. |

Title | Real-Time Gaze Tracking with Appearance-Based Models | Type | Journal Article | ||

Abstract | Psychological evidence has emphasized the importance of eye gaze analysis in human computer interaction and emotion interpretation. To this end, current image analysis algorithms take into consideration eye-lid and iris motion detection using colour information and edge detectors. However, eye movement is fast and and hence difficult to use to obtain a precise and robust tracking. Instead, our
method proposed to describe eyelid and iris movements as continuous variables using appearance-based tracking. This approach combines the strengths of adaptive appearance models, optimization methods and backtracking techniques.Thus, in the proposed method textures are learned on-line from near frontal images and illumination changes, occlusions and fast movements are managed. The method achieves real-time performance by combining two appearance-based trackers to a backtracking algorithm for eyelid estimation and another for iris estimation. These contributions represent a significant advance towards a reliable gaze motion description for HCI and expression analysis, where the strength of complementary methodologies are combined to avoid using high quality images, colour information, texture training, camera settings and other time-consuming processes. |

Title | Registration-based Moving Object Detection from a Moving Camera | Type | Conference Article | ||
Year | 2008 | Publication | IROS2008 2nd Workshop on Perception, Planning and Navigation for Intelligent Vehicles | Abbreviated Journal | |
Volume | Issue | Pages | 65–69 | ||
Keywords | |||||
Abstract | This paper presents a robust approach for detecting moving objects from on-board stereo vision systems. It relies on a feature point quaternion-based registration, which avoids common problems that appear when computationally expensive iterative-based algorithms are used on dynamic environments. The proposed approach consists of three stages. Initially, feature points are extracted and tracked through consecutive frames. Then, a RANSAC based approach is used for registering
two 3D point sets with known correspondences by means of the quaternion method. Finally, the computed 3D rigid displacement is used to map two consecutive frames into the same coordinate system. Moving objects correspond to those areas with large registration errors. Experimental results, in different scenarios, show the viability of the proposed approach. |

Title | A Variational Framework for Assessment of the Left Ventricle Motion | Type | Journal Article | ||
Year | 2008 | Publication | International Journal Mathematical Modelling of Natural Phenomena | Abbreviated Journal | |
Volume | 3 | Issue | 6 | Pages | 76-100 |
Keywords | Key words: Left Ventricle Dynamics, Ventricular Torsion, Tagged Magnetic Resonance, Motion Tracking, Variational Framework, Gabor Transform. | ||||
Abstract | Impairment of left ventricular contractility due to cardiovascular diseases is reflected in left ventricle (LV) motion patterns. An abnormal change of torsion or long axis shortening LV values can help with the diagnosis and follow-up of LV dysfunction. Tagged Magnetic Resonance (TMR) is a widely spread medical imaging modality that allows estimation of the myocardial tissue local deformation. In this work, we introduce a novel variational framework for extracting the left ventricle dynamics from TMR sequences. A bi-dimensional representation space of TMR images given by Gabor filter banks is defined. Tracking of the phases of the Gabor response is combined using a variational framework which regularizes the deformation field just at areas where the Gabor amplitude drops, while restoring the underlying motion otherwise. The clinical applicability of the proposed method is illustrated by extracting normality models of the ventricular torsion from 19 healthy subjects. | ||||
