  • Jindal, Nihar; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    The purpose of this paper is to examine (1) some of the models commonly used to represent fading,/nand (2) the information-theoretic metrics most commonly used to evaluate performance over those models. We raise the question ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Springer, 2016)
    Most of the image retrieval approaches nowadays are based on the Bag-of-Words (BoW) model, which allows for representing an image efficiently and quickly. The efficiency of the BoW model is related to the efficiency of the ...
  • Bozkurt, Baris (Universitat Pompeu Fabra, 2012)
    For computational studies of makam music, it is essential to gather a list of characteristics that constitute a makam and explore corresponding quantitative features for automatic/nanalysis. This study is such an attempt ...
  • Hernández Leo, Davinia; Moreno, Verónica (2014-11-21)
    The role of Bachelors' Final Projects (BFP) in Engineering Education is critical since it offers the opportunity for students to integrate the application of specific and transversal competences they have developed along ...

    We present an innovative image analyisis pipeline to perform/npatient-speci c biomechanical and functional simulations of the inner human/near. A high-resolution, cadaveric, mCT volumetric image portraying/nthe detailed ...
  • Oramas, Sergio; Gómez, Francisco; Gómez Gutiérrez, Emilia, 1975-; Mora, Joaquín (International Society for Music Information Retrieval (ISMIR), 2015)
    Online information about flamenco music is scattered over different sites and knowledge bases. Unfortunately, there is no common repository that indexes all these data. In this work, information related to flamenco ...
  • Font Corbera, Frederic; Serrà Julià, Joan; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2012)
    Collaborative tagging has emerged as an efficient way to/nsemantically describe online resources shared by a community/nof users. However, tag descriptions present some/ndrawbacks such as tag scarcity or concept ...
  • Mille, Simon; Carlini, Roberto; Burga Díaz, Alicia; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    We present the contribution of Universitat Pompeu Fabra’s NLP group to the Sem-Eval Task 9.2 (AMR-to-English Generation). The proposed generation pipeline comprises: (i) a series of rule-based graphtransducers for the ...
  • Akkermans, Vincent; Font Corbera, Frederic; Funollet, Jordi; de Jong, Bram; Roma Trepat, Gerard; Togias, Stelios; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2011)
    Freesound.org is an online collaborative sound database where people from different disciplines share recorded sound clips under Creative Commons licenses. It was started in 2005 and it is being further developed by the ...
  • Fonseca, Eduardo; Pons Puig, Jordi; Favory, Xavier; Font Corbera, Frederic; Bogdanov, Dmitry; Ferraro, Andrés; Oramas, Sergio; Porter, Alastair; Serra, Xavier (International Society for Music Information Retrieval (ISMIR), 2017)
    Openly available datasets are a key factor in the advancement of data-driven research approaches, including many of the ones used in sound and music computing. In the last few years, quite a number of new audio datasets ...
  • Font Corbera, Frederic (2017)
    Freesound Explorer is a visual interface for exploring Freesound content in a two-dimensional space and creating music by linking content in that space. Freesound Explorer is implemented as a web application which takes ...
  • Roma Trepat, Gerard; Herrera Boyer, Perfecto; Serra, Xavier (2009)
    The habit of sharing media online has created a platform with great potential for creative applications that are accessible to large numbers of users with very different backgrounds. As an example, a lively community has ...
  • Albó Pérez, Laia; Gelpí Arroyo, Cristina (2017)
    This paper presents a case study of transforming an existing MOOC into a SPOC for being used in a campus course using a blended learning ap-proach with the aim of providing a reflection of the experience and reporting the ...
  • Ruiz, Adrià; Van de Weijer, Joost; Binefa i Valls, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    Limited annotated training data is a challenging problem in Action Unit recognition. In this paper, we investigate how the use of large databases labelled according to the 6 universal facial expressions can increase the ...
  • Boutros, Joseph Jean; Zémor, Gilles; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2008)
    We show how to build full-diversity product codes under both iterative encoding and decoding over non-ergodic channels, in presence of block erasure and block fading. The concept of a rootcheck or a root subcode is introduced ...
  • 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)
