  • 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. ...
  • 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 (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 (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 (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 ...
  • Tauste Campo, Adrià; Guillén i Fàbregas, Albert; Biglieri, Ezio (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    We analyze multiuser detection under the assumption that the number of users accessing the channel is unknown by the receiver. Our main goal is to determine the performance loss caused by the need for estimating the ...
  • Farrús, Mireia; Ejarque, Pascual; Temko, Andrey; Hernando, Javier (Springer, 2007)
    It has been shown that prosody helps to improve voice spectrum based speaker recognition systems. Therefore, prosodic features can also be used in multimodal person verification in order to achieve better results. In this ...
  • Barbieri, Francesco; Kruszewski, German; Ronzano, Francesco; Saggion, Horacio (ACM Association for Computer Machinery, 2016)
    Choosing the right emoji to visually complement or con- dense the meaning of a message has become part of our daily life. Emojis are pictures, which are naturally combined with plain text, thus creating a new form of ...
  • Michos, Konstantinos; Hernández Leo, Davinia; Jiménez-Morales, Manel (CEUR Workshop Proceedings, 2017)
    A range of data analytics is provided to educators about the profile, behavior and satisfaction of students participating in a Massive Open Online Course (MOOC). However, limited research has been conducted on how ...
  • Barbieri, Francesco; Camacho-Collados, Jose (ACL (Association for Computational Linguistics), 2018)
    In this paper we analyze the use of emojis in social media with respect to gender and skin tone. By gathering a dataset of over twenty two million tweets from United States some findings are clearly highlighted after ...
