Recent Submissions

  • Sugito, Yasuko; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    In image quality assessments, the results of subjective evaluation experiments that use the double-stimulus impairment scale (DSIS) method are often expressed in terms of the mean opinion score (MOS), which is the average ...
  • Sugito, Yasuko; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Full-reference objective quality metrics for high dynamic range (HDR) images must be validated in terms of their consistency with subjective evaluation results, and previous studies have found a number of metrics that ...
  • Zabaleta, Itziar; Bertalmío, Marcelo (Society of Motion Picture and Television Engineers (SMPTE), 2018)
    In professional cinema, the intended artistic look of the movie informs the creation of a static 3D LUT that is applied on set, where further manual modifications to the image appearance are registered as 10-parameter ...
  • Vu-Thanh, Olivier; Canham, Trevor; Vazquez-Corral, Javier; Gil Rodríguez, Raquel; Bertalmío, Marcelo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    By capturing a more complete rendition of scene light than standard 2D cameras, light-field technology represents an important step towards closing the gap between live action cinematography and computer graphics. Light-field ...
  • Beardsley, Marc; Martínez Moreno, Judit; Hernández Leo, Davinia (2020)
    Many students use ineffective learning strategies and lack confidence in their learning skills and knowledge. This paper presents the results of a pre- and post-survey study involving first-year university students that ...
  • Beardsley, Marc; Martínez Moreno, Judit; Hernández Leo, Davinia (2020)
    This paper presents the results of a survey on teacher formation and beliefs related to the science of learning (e.g. the science of how people learn) completed by in-service and pre-service teachers. The study results ...
  • Alonso-Jiménez, Pablo; Bogdanov, Dmitry; Serra, Xavier (2020)
    We present the integration of various CNN TensorFlow models developed for different MIR tasks into Essentia. This is a continuation of our previous work [1], extending the list of supported models and adding new algorithms ...
  • Correya, Albin Andrew; Bogdanov, Dmitry; Joglar-Ongay, Luis; Serra, Xavier (2020)
    Open-source software libraries for audio/music analysis and feature extraction have a significant impact on the development of Audio Signal Processing and Music Information Retrieval (MIR) systems. Despite the abundance of ...
  • Ramires, António; Font, Frederic; Bogdanov, Dmitry; Smith, Jordan B. L.; Yang, Yi-Hsuan; Ching, Joann; Chen, Bo-Yu; Wu, Yueh-Kao; Wei-Han, Hsu; Serra, Xavier (2020)
    Music loops are essential ingredients in electronic music production, and there is a high demand for pre-recorded loops in a variety of styles. Several commercial and community databases have been created to meet this ...
  • Franzoni, Francesco; Abellán Álvarez, Iván; Daza, Vanesa (2020)
    Over the past twenty years, the number of devices connected to the Internet grew exponentially. Botnets bene ted from this rise to increase their size and the magnitude of their attacks. However, they still have a weak ...
  • Ramires, António; Bernardes, Gilberto; Davies, Matthew E. P.; Serra, Xavier (DAFx, 2020)
    In this paper, we present TIV.lib, an open-source library for the content-based tonal description of musical audio signals. Its main novelty relies on the perceptually-inspired Tonal Interval Vector space based on the ...
  • Shakespeare, Dougal; Porcaro, Lorenzo; Gómez Gutiérrez, Emilia, 1975-; Castillo, Carlos (CEUR Workshop Proceedings, 2020)
    Music Recommender Systems (mRS) are designed to give personalised and meaningful recommendations of items (i.e. songs, playlists or artists) to a user base, thereby reflecting and further complementing individual users’ ...
  • Roma Trepat, Gerard; Serra, Xavier (Web Audio Conference, 2015)
    On the web, searching for sounds is usually limited to text queries. This requires adding textual descriptions to each audio file, which is indexed effectively as a text document. Recent developments in browser technologies ...
  • Roma Trepat, Gerard; Serra, Xavier (Web Audio Conference, 2015)
    Technologies for discovering sounds in large databases can help breaking the boundary between exploration and music performance. In this paper, we present a system for exploring loops from Freesound. Sound files are grouped ...
  • Font, Frederic; Oramas, Sergio; Fazekas, György; Serra, Xavier (CEUR Workshop Proceedings, 2014)
    Currently proposed tagging ontologies are mostly focused on the definition of a common schema for representing the agents involved in a tagging process. In this paper we describe preliminary research around the idea of ...
  • Do, Heedong; Lee, Namyoon; Lozano Solsona, Angel (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    We establish an upper bound on the informationtheoretic capacity of line-of-sight (LOS) multiantenna channels with arbitrary antenna arrangements and identify array structures that, properly configured, can attain at least ...
  • Albó, Laia; Beardsley, Marc; Martínez Moreno, Judit; Santos Rodríguez, Patrícia; Hernández Leo, Davinia (Springer, 2020)
    COVID-19 thrust teachers into emergency online pedagogy. Teachers had to rapidly digitize their practices. A week into compulsory online teaching, we captured a snapshot of teacher experiences to identify their impressions ...
  • Papiotis, Panagiotis, 1985-; Herrera Boyer, Perfecto, 1964-; Marchini, Marco, 1984-; Maestre Gómez, Esteban (University of Jyväskylä, 2013)
    In a musical ensemble musicians can influence each other’s performance in terms not only of timing but also in other aspects of the performance such as dynamics, intonation, and timbre. The goal of this work is to test ...
  • Ostuni, Vito Claudio; Di Noia, Tommaso; Di Sciascio, Eugenio; Oramas, Sergio; Serra, Xavier (ACM Association for Computer Machinery, 2015)
    In this work we describe a hybrid recommendation approach for recommending sounds to users by exploiting and semantically enriching textual information such as tags and sounds descriptions. As a case study we used Freesound, ...
  • Font Corbera, Frederic; Roma Trepat, Gerard; Serra, Xavier (ACM Association for Computer Machinery, 2013)
    Freesound is an online collaborative sound database where people with diverse interests share recorded sound samples under Creative Commons licenses. It was started in 2005 and it is being maintained to support diverse ...
