  • Ruiz, Adrià; Martinez, Oriol; Binefa i Valls, Xavier; Sukno, Federico Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    An essential issue when training and validating computer vision systems for affect analysis is how to obtain reliable ground-truth labels from a pool of subjective annotations. In this paper, we address this problem ...
  • Galdran, Adrian; Vazquez-Corral, Javier; Pardo, David; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    We propose a novel image-dehazing technique based on the minimization of two energy functionals and a fusion scheme to combine the output of both optimizations. The proposed fusion-based variational image-dehazing (FVID) ...
  • Farrús, Mireia; Anguita, Jan; Hernando, Javier; Cerdà, Ramon (Dirección Xeral de Creación e Difusión Cultural, 2007)
    Los sistemas automáticos de reconocimiento de locutor más utilizados recientemente están basados en características acústicas de bajo nivel, como las magnitudes espectrales, las frecuencias de los formantes, etc. Sin ...
  • Zamir, Syed Waqas; Vazquez-Corral, Javier; Bertalmío, Marcelo (Society of Photo Optical Instrumentation Engineers (SPIE), 2015)
    Wide gamut digital display technology, in order to show its full potential in terms of colors, is creating an opportunity to develop gamut extension algorithms (GEAs). To this end, in this work we present two contributions. ...
  • Fonseca, Eduardo; Plakal, Manoj; Font, Frederic; Ellis, Daniel P. W.; Favory, Xavier; Pons Puig, Jordi; Serra, Xavier (Tampere University of Technology, 2018)
    This paper describes Task 2 of the DCASE 2018 Challenge, titled “General-purpose audio tagging of Freesound content with AudioSet labels”. This task was hosted on the Kaggle platform as “Freesound General-Purpose Audio ...
  • Boutros, Joseph Jean; Zémor, Gilles; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    A new graph-based construction of generalized low density codes (GLD-Tanner) with binary BCH constituents is described. The proposed family of GLD codes is optimal on block erasure channels and quasi-optimal on block fading ...
  • Segovia-Aguas, Javier; Jiménez, Sergio; Jonsson, Anders, 1973- (IJCAI, 2017)
    This paper presents a novel approach for generating Context-Free Grammars (CFGs) from small sets of input strings (a single input string in some cases). Our approach is to compile this task into a classical planning ...
  • Miron, Marius; Janer Mestres, Jordi; Gómez Gutiérrez, Emilia, 1975- (Aalto University, 2017)
    Deep learning approaches have become increasingly popular in estimating time-frequency masks for audio source separation. However, training neural networks usually requires a considerable amount of data. Music data is ...
  • Maestre Gómez, Esteban; Pérez Carrillo, Alfonso Antonio, 1977-; Ramírez, Rafael,1966- (International Computer Music Association, 2010)
    This paper presents a framework in which samples of bowing gesture parameters are retrieved and concatenated from a database of violin performances by attending to an annotated input score. Resulting bowing parameter signals ...
  • Knees, Peter; Andersen, Kristina; Jordà Puig, Sergi; Hlatky, Michael; Geiger, Günter; Gaebele, Wulf; Kaurson, Roman (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    We present the GiantSteps project, an EU-funded project/ninvolving institutions from academia, practitioners, and industrial/npartners with the goal of developing new concepts for/nintelligent and collaborative interfaces ...
  • Ramírez Jávega, Miquel; Geffner, Héctor (Association for the Advancement of Artificial Intelligence (AAAI), 2011)
    Plan recognition is the problem of inferring the goals and plans of an agent from partial observations of her behavior. Recently, it has been shown that the problem can be formulated and solved using/nplanners, reducing ...
  • Bandiera, Giuseppe; Romani Picas, Oriol; Tokuda, Hiroshi; Hariya, Wataru; Oishi, Koji; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2016)
    We introduce good-sounds.org, a community driven framework based on freesound.org to explore the concept of goodness in instrumental sounds. Goodness is considered here as the common agreed basic sound quality of ...
  • Hernández Leo, Davinia (2016)
    Competencias transversales como el trabajo en equipo o el dominio del inglés son objeto/nexplicitico de formación en diferentes asignaturas de los planes de estudio de las Ingenierías/nTIC de la Universitat Pompeu Fabra ...
  • Derkach, Dmytro; Ruiz Ovejero, Adrià; Sukno, Federico Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    In this paper we present a system that is able to estimate head pose using only depth information from consumer RGB-D cameras such as Kinect 2. In contrast to most approaches addressing this problem, we do not rely on ...
  • Hernández Leo, Davinia; Agostinho, Shirley; Beardsley, Marc; Bennet, Sue; Lockyer, Lori (IATED, 2017)
    Designing learning experiences for students is a key responsibility of teachers. This involves designing stimulating and engaging tasks, selecting and creating appropriate resources, and deciding how best to support students ...
  • Segovia-Aguas, Javier; Jiménez, Sergio; Jonsson, Anders, 1973- (Association for the Advancement of Artificial Intelligence (AAAI), 2016)
    Finite State Controllers (FSCs) are an effective way/nto represent sequential plans compactly. By imposing/nappropriate conditions on transitions, FSCs/ncan also represent generalized plans that solve a/nrange of planning ...
  • Gil Rodríguez, Raquel; Bertalmío, Marcelo (The Society for Imaging Science and Technology (IS&T), 2016)
    In this paper we present a simple and affordable method to generate high quality video from a high dynamic range scene. It is performed without utilizing extra lighting, neither alternating exposures, nor operating with ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Benton, DM (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This article proposes a frequency agile antenna whose operating frequency band can be switched. The design is based on a Vivaldi antenna. High-performance radio-frequency microelectromechanical system (RF-MEMS) switches ...
  • Borda Fortuny, Cristina; Tong, Kin-Fai; Chetty, Kevin; Brittan, P. (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    A frequency agile Vivaldi antenna whose operating frequency band can be switched is pro- posed. High-performance radio-frequency micro- electromechanical system (RF-MEMS) switches al- low tuning of the operational band ...
