  • Serra, Xavier (International Computer Music Conference, 1986)
    This paper presents a computer model for bar percussion instruments that captures their main physical characteristics in a very flexible structure. The starting point is current knowledge of the acoustics of the instruments. ...
  • Malinverni, Laura; Valero, Cristina; Schaper, Marie-Monique; Parés, Narcís, 1966- (ACM Association for Computer Machinery, 2018)
    Augmented and Mixed Reality mobile technologies are becoming an emerging trend in the development of play and learning experiences for children. This tendency requires a deeper understanding of their specificities to ...
  • Pérez Sanagustín, Maria del Mar; Santos Rodríguez, Patrícia; Moghnie, Ayman; Hernández Leo, Davinia; Blat, Josep (Inderscience Enterprises Ltd, 2009)
    The emergence of the Web 2.0 technologies in the last years have/nchanged the way people interact with knowledge. Services for cooperation and/ncollaboration have placed the user in the centre of a new knowledge building/nspace. ...
  • Cardelino, Juan; Caselles, Vicente; Bertalmío, Marcelo; Randall, Gregory (SIAM (Society for Industrial and Applied Mathematics), 2013)
    We present a novel segmentation algorithm based on a hierarchical representation of images. The main contribution of this work is to explore the capabilities of the a contrario reasoning when applied to the segmentation ...
  • Uyar, Burak; Atli, Hasan Sercan; Sentürk, Sertan; Bozkurt, Baris; Serra, Xavier (ACM Association for Computer Machinery, 2014)
    Each music tradition has its own characteristics in terms of melodic, rhythmic and timbral properties as well as semantic understandings. To analyse, discover and explore these culture-specific characteristics, we need ...
  • Scarlett, Jonathan; Somekh-Baruch, Anelia; Martinez, Alfonso; Guillén i Fàbregas, Albert (Institute of Electrical and Electronics Engineers (IEEE), 2015)
    This paper studies the mismatched decoding problem for binary-input discrete memoryless channels. An example is provided for which an achievable rate based on superposition coding exceeds the Csiszár-Körner-Hui rate, thus ...
  • Pasarella Sánchez, Ana Edelmira; Lobo, Jorge (ACM Association for Computer Machinery, 2017)
    Relationships like friendship to limit access to resources have been part of social network applications since their beginnings. Describing access control policies in terms of relationships is not particular to social ...
  • Ghimpeteanu, Gabriela; Batard, Thomas; Bertalmío, Marcelo; Levine, Stacey (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    In this paper, we consider an image decomposition model that provides a novel framework for image denoising. The model computes the components of the image to be processed in a moving frame that encodes its local geometry ...
  • Oramas, Sergio; Nieto Caballero, Oriol; Sordo, Mohamed; Serra, Xavier (ACM Association for Computer Machinery, 2017)
    An increasing amount of digital music is being published daily. Music streaming services often ingest all available music, but this poses a challenge: how to recommend new artists for which prior knowledge is scarce? In ...
  • Štajner , Sanja; Béchara, Hannah; Saggion, Horacio (ACL (Association for Computational Linguistics), 2015)
    In the last few years, there has been a growing number of studies addressing the Text Simplification (TS) task as a monolingual machine translation (MT) problem which translates from ‘original’ to ‘simple’ language. ...
  • Mille, Simon; Wanner, Leo (ACL (Association for Computational Linguistics), 2017)
    This demo paper presents the multilingual deep sentence generator developed by the TALN group at Universitat Pompeu Fabra, implemented as a series of rule-based graphtransducers.
  • Tauste Campo, Adrià; Vazquez-Vilar, Gonzalo; Guillén i Fàbregas, Albert; Koch, Tobias; Martinez, Alfonso (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    This paper studies the random-coding exponent of joint source-channel coding for a scheme where source messages are assigned to disjoint subsets (referred to as classes), and codewords are independently generated according ...
  • Srinivasamurthy, Ajay; Holzapfel, Andre; Cemgil, Ali Taylan; Serra, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Most musical phenomena involve repetitive structures that enable listeners to track meter, i.e. the tactus or beat, the longer over-arching measure or bar, and possibly other related layers. Meters with long measure duration, ...
  • Ramírez, Rafael,1966-; Hazan, Amaury; Maestre Gómez, Esteban; Serra, Xavier (MIT Press, 2008)
    We describe an evolutionary approach to inducing a generative model of expressive music performance for Jazz saxophone. We begin with a collection of audio recordings of real Jazz saxophone performances from which we extract ...
  • Batard, Thomas; Bertalmío, Marcelo (Springer, 2018)
    Human perception involves many features like contours, shapes, textures, and colors to name a few. Whereas several geometric models for contours, shapes and textures perception have been proposed, the geometry of color ...
  • Adiloglu, Kamil; Anniés, Robert; Wahlen, Elio; Purwins, Hendrik; Obermayer, Klaus (Institute of Electrical and Electronics Engineers (IEEE), 2012)
    Studies of Gaver (W. W. Gaver, “How do we hear in the world? Explorations in ecological acoustics,” Ecological Psychology, 1993) revealed that humans categorize everyday sounds considering the processes that have generated ...
  • Steck, Kathrin; Veit, Daniel; Grandy, Ronald; Bermúdez i Badia, S.; Mathews, Zenon; Verschure, Paul F. M. J.; Hansson, B. S. (Bill S.), 1959-; Knaden, Markus (Nature Publishing Group, 2012)
    How can odor-guided behavior of numerous individual Drosophila be assessed automatically with high temporal resolution? For this purpose we introduce the automatic integrated tracking and odor-delivery system Flywalk. In ...
  • Mavropoulos, Thanassis; Liparas, Dimitris; Symeonidis, Spyridon; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Springer, 2017)
    The automatic extraction of relations between medical entities found in related texts is considered to be a very important task, due to the multitude of applications that it can support, from question answering systems to ...
  • Gialampoukidis, Ilias; Vrochidis, Stefanos; Kompatsiaris, Ioannis; Wanner, Leo (Springer, 2016)
    Nowadays there is an important need by journalists and media monitoring companies to cluster news in large amounts of web articles, in order to ensure fast access to their topics or events of interest. Our aim in this work ...
  • Gialampoukidis, Ilias; Moumtzidou, Anastasia; Liparas, Dimitris; Vrochidis, Stefanos; Kompatsiaris, Ioannis (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Nowadays, multimedia retrieval has become a task of high importance, due to the need for efficient and fast access to very large and heterogeneous multimedia collections. An interesting challenge within the aforementioned ...
