Multimedia Retrieval by Means of Merge of Results from Textual and Content Based Retrieval Subsystems
2010
The main goal of this paper it is to present our experiments in ImageCLEF 2009 Campaign (photo retrieval task). In 2008 we proved empirically that the Text-based Image Retrieval (TBIR) methods defeats the Content-based Image Retrieval CBIR "quality" of results, so this time we developed several experiments in which the CBIR helps the TBIR. The TBIR System [6] main improvement is the named-entity sub-module. In case of the CBIR system [3] the number of low-level features has been increased from the 68 component used at ImageCLEF 2008 up to 114 components, and only the Mahalanobis distance has been used. We propose an ad-hoc management of the topics delivered, and the generation of XML struct…
Variable Neighborhood Search for the Vertex Separation Problem
2012
The vertex separation problem belongs to a family of optimization problems in which the objective is to nd the best separator of vertices or edges in a generic graph. This optimization problem is strongly related to other well-known graph problems; such as the Path-Width, the Node Search Number or the Interval Thickness, among others. All of these optimization problems are NP-hard and have practical applications in VLSI, computer language compiler design or graph drawing. Up to know, they have been generally tackled with exact approaches, presenting polynomial-time algorithms to obtain the optimal solution for speci c types of graphs. However, in spite of their practical applications, these…
Machine Learning-Based View Synthesis in Fourier Lightfield Microscopy
2022
Current interest in Fourier lightfield microscopy is increasing, due to its ability to acquire 3D images of thick dynamic samples. This technique is based on simultaneously capturing, in a single shot, and with a monocular setup, a number of orthographic perspective views of 3D microscopic samples. An essential feature of Fourier lightfield microscopy is that the number of acquired views is low, due to the trade-off relationship existing between the number of views and their corresponding lateral resolution. Therefore, it is important to have a tool for the generation of a high number of synthesized view images, without compromising their lateral resolution. In this context we investigate h…
Introducing Usability in a Conceptual Modeling-Based Software Development Process
2012
Usability plays an important role to satisfy users? needs. There are many recommendations in the HCI literature on how to improve software usability. Our research focuses on such recommendations that affect the system architecture rather than just the interface. However, improving software usability in aspects that affect architecture increases the analyst?s workload and development complexity. This paper proposes a solution based on model-driven development. We propose representing functional usability mechanisms abstractly by means of conceptual primitives. The analyst will use these primitives to incorporate functional usability features at the early stages of the development process. Fo…

Reseña del libro Informatique pour les Sciences de l'Homme. Limites de la formalisation du raisonnement, de Mario Borillo
1985
Se trata de una reseña escrita por José Vidal-Beneyto sobre el libro de Mario Borillo "Informatique pour les Sciences de l'Homme. Limites de la formalisation du raisonnement". En el texto se indica que la reseña es para el diario francés "Le Monde", pero se desconoce si finalmente fue publicada en ese u otro medio.
Educación artística : revista de investigación
2013
Resumen: El proyecto MeTaEducArte, surgió tras una larga experiencia docente-artística, en respuesta a una intensa reflexión sobre la propia práctica educativa, se detectó la necesidad de aplicar diferentes métodos didácticos, en función de las demandas del nuevo tipo de estudiantes que encontramos actualmente en nuestras aulas, en el contexto de la Formación de Profesorado de los estudios de Grado de Infantil y Primaria, en la Universidad Autónoma de Madrid. Así, en el año 2011, nace el terminoMeTaEducArte,dando nombreal Proyecto de Innovación Docente, que tiene como principal objetivo que los alumnos y alumnas disfruten, aprendan y se comprometan con la educación artística, practicando la…
Some Results Using Different Approaches to Merge Visual and Text-Based Features in CLEF’08 Photo Collection
2009
This paper describes the participation of the MIRACLE team at the ImageCLEF Photographic Retrieval task of CLEF 2008. We succeeded in submitting 41 runs. Obtained results from text-based retrieval are better than content-based as previous experiments in the MIRACLE team campaigns [5, 6] using different software. Our main aim was to experiment with several merging approaches to fuse text-based retrieval and content-based retrieval results, and it happened that we improve the text-based baseline when applying one of the three merging algorithms, although visual results are lower than textual ones.
Actores sintéticos en tiempo real: Nuevas estructuras de datos y métodos para su integración en aplicaciones de simulación.
2004
La forma más extendida de implementar una aplicación de simulación es mediante la utilización de un grafo de escena. Este tipo de estructura resulta muy adecuado para definir escenas estáticas, pero presenta serias carencias a la hora de representar estructuras articuladas, u objetos con comportamientos complejos. Ambas circunstancias se dan en el caso de los actores virtuales.Este trabajo define nuevas estructuras de datos y métodos que permiten integrar de una forma adecuada actores virtuales en una aplicación de simulación:1-Se presentan dos nuevos tipos de nodos (Actor y Skeleton), que actúan como elemento modular para la definición y gestión de cualquier tipo de actor virtual. En el di…
