ACKNOWLEDGMENTSQuiero aprovechar estas líneas para mostrar mi agradecimiento a todas las personas que de una forma o de otra han contribuido a que esta tesis se haya hecho realidad.En primer lugar quiero agradecer sinceramente a mis directores de tesis todo su apoyo, paciencia y dedicación. Ismael, a quién hace tiempo que no considero simplemente mi director de tesis, sino un amigo y del que he aprendido muchas cosas, sobre todo en cuanto a traducción automática se refiere. En cuanto a Enrique, no puedo sino considerarlo como un auténtico maestro para mí. Gracias por enseñarme que el detalle es realmente importante y por reconducir mis raras e improvisadas propuestas. En definitiva, si de alguna forma ahora puedo considerarme un investigador, es fundamentalmente gracias a ellos. También me gustaría incluir aquí a Francisco Casacuberta, con quien he compartido varios proyectos y artículos y del que también he tenido oportunidad de aprender muchas cosas.No quiero dejar pasar la oportunidad de agradecer a todos los que de uno u otro modo han compartido conmigo su aprendizaje en el mundo de la investigación. Empezando con mis compañeros en el proyecto TT2: Antonio, Elsa y Jorge, con quien tantos momentos entrañables compartí. Extiendo este agradecimiento a todos los miembros del ITI que me brindaron una extraordinaria acogida durante mis casi tres años en Valencia: Alejandro (quien siempre tiene algún truco nuevo que enseñarte), José Ramón, Dani (con quien siempre se mantienen conversaciones productivas), Javi, Jose, Jorge, Vicent y a todos los miembros del grupo PRHLT. También quiero agradecer a todos los integrantes del grupo SIMD, especialmente a sus directores José Antonio y José Miguel por acogerme a mi regreso de Valencia. Porúltimo, quiero también mostrar mi agradecimiento a José Oncina, por encontrar un algoritmo que hace mejores los resultados de predicción de texto aquí presentados.En el aspecto personal, quiero agradecer a mis padres todo su apoyo y cariño en las diferentes etapas de mi vida. También al resto de mi familia. A todos mis amigos, por saber perdonar mi falta de dedicación con ellos debido a lo absorbente de este trabajo. Porúltimo, mi más profundo agradecimiento a Sonia, por todo su apoyo y amor durante estos años tan complicados.Finalmente, y citando a los geniales "Monty Python": and now, for something completely different ... Luis Rodríguez Ruiz ABSTRACTThis thesis is about Pattern Recognition. In the last decades, huge efforts have been made to develop automatic systems able to rival human capabilities in this field. Although these systems achieve high productivity rates, they are not precise enough in most situations. Humans, on the contrary, are very accurate but comparatively quite slower. This poses an interesting question: the possibility of benefiting from both worlds by constructing cooperative systems.This thesis presents diverse contributions to this kind of collaborative approach. The point is to improve the Pattern Recognition systems by properly introducing a human operator i...
In this work we explore the automatic 3D modeling of a person using images acquired from a range camera. Using only one range camera and two mirrors, the objective is to obtain a full 3D model with one single snapshot. The combination of the camera and the two mirrors give us three non-overlapping meshes, making impossible to use common zippering algorithms based on overlapping meshes. Therefore, Dynamic Time Warping algorithm is used to find the best matching between boundaries of the meshes. Experimental results and error evaluations are given to show the robustness and efficiency of our method.
Abstract-The Workshop of Physical Agents intends to be a forum for information and experience exchange in different areas regarding the concept of agent in physical environments, especially applied to the control and coordination of autonomous systems: robots, mobile robots, industrial processes or complex systems. This special issue is devoted to the selected papers presented in the WAF11 that took place in Albacete (SPAIN) from 5th to 6th of September.Index Terms-WAF, Physical Agents. I. THE XII EDITION OF THE WORKSHOP OF PHYSICAL AGENTS SINCE its first edition in 2000, the Workshop of Physical Agents has served as a meeting point for different research groups from different areas of knowledge and with a common interest: physical agents. Most of the groups that actively participate in RedAF (the Spanish Network of Physical Agents) took part in this event. RedAF is the main local sponsor organizing this Workshop. This annual event has three main objectives:• Providing a forum for communication on research, technological innovation and technology transfer in the field of physical agents, encompassing areas such as embedded systems, artificial intelligence, mobile robotics, • Promoting communication among researchers from different research groups related to physical agents.• Providing a mean for active and efficient transfer of research and technological upgrading. The XII edition was a complete success, since these goals were achieved once again. We started on September 5th, enjoying the plenary talk "Social Robots" given by Professor Carlos Balaguer from the University of Carlos III, Spain. After that, we had two working sessions on "Robots and Agents" and "Localization and Planning", consisting of four talks per session. Finally, on September 6th we attended the plenary talk "Visual Place Classification" given by Dr. Barbara Caputo from the IDIAP Research Center, Switzerland. Next, we had a working session on "Vision and Sensors", a working session on "Applications and Interaction" and, after lunch we had the demo session.As a summary, a total of twenty papers were presented in the four working sessions. As in previous editions of the workshop, the live demos and exhibitions attracted the attention of significant media press, such as TV news and different articles in the local, regional and national newspapers, were published. We had, as well, the opportunity to interact with the mobile social robot Loky, designed by the SIMD group of Ismael García-Varea is with the University of Castilla-La Mancha, Spain. E-mail: Ismael.Garcia@uclm.esLuis Rodríguez-Ruiz is with the University of Castilla-La Mancha, Spain. E-mail: Luis.RRuiz@uclm.es the University of Castilla-La Mancha in conjuntion with the RoboLab group of the University of Caceres, and equiped with different elements developed by: Robotnik Automation, S.L., and IADex, S.L. These two companies also showed their last products and developments in their exhibition stands during the two days of the workshop. Also, we enjoyed the Nao Robots soccer team from the ...
