    Speech is a rich biometric signal that contains information about the identity, gender and emotional state of the speaker. In this work, we explore its potential to generate face images of a speaker by conditioning a ...
  • RVOS: end-to-end recurrent network for video object segmentation 

    Ventura, Carles; Bellver, Míriam; Girbau, Andreu; Salvador Aguilera, Amaia; Marqués Acosta, Fernando; Giró Nieto, Xavier (Computer Vision Foundation, 2019)
    Conference lecture
    Open Access
    Multiple object video object segmentation is a challenging task, specially for the zero-shot case, when no object mask is given at the initial frame and the model has to find the objects to be segmented along the sequence. ...
  • Inverse cooking: recipe generation from food images 

    Salvador Aguilera, Amaia; Drozdzal, Michal; Giró Nieto, Xavier; Romero, Adriana (Computer Vision Foundation, 2019)
    Conference report
    Open Access
    People enjoy food photography because they appreciate food. Behind each meal there is a story described in a complex recipe and, unfortunately, by simply looking at a food image we do not have access to its preparation ...
  • Assessing knee OA severity with CNN attention-based end-to-end architectures 

    Górriz, Marc; Antony, Joseph; McGuinness, Kevin; Giró Nieto, Xavier; O'Connor, Noel (2019)
    Conference lecture
    Open Access
    This work proposes a novel end-to-end convolutional neural network (CNN) architecture to automatically quantify the severity of knee osteoarthritis (OA) using X-Ray images, which incorporates trainable attention modules ...
  • Benefits of applying nodal sampling to SMOS data over semi-enclosed seas and strongly RFI-contaminated regions 

    González Gambau, Verónica; Olmedo, Estrella; Martinez, J.; Turiel, Antonio; Corbella Sanahuja, Ignasi; Oliva, Roger; Martín Neira, Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2018)

    Radio Frequency Interferences (RFI) are still an important source of contamination in SMOS data. The application of nodal sampling (NS) to brightness temperature images helps to mitigate the degradation that RFIs produce ...
  • 5G framework for automated network adaptation in mission critical services 

    Jimeno, Elisa; Pérez Romero, Jordi; Vilà Muñoz, Irene; Blanco Jauregi, Begoña; Sanchoyerto, Aitor; Fernández, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Open Access
    Mission Critical Services (MCS) are gaining interest among network operators to offer alternative communications than conventional trunked radio systems. They promise a simplified management of cloud and radio resources ...
  • One shot learning for generic instance segmentation in RGBD videos 

    Lin, Xiao; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (Scitepress, 2019)
    Conference report
    Open Access
    Hand-crafted features employed in classical generic instance segmentation methods have limited discriminative power to distinguish different objects in the scene, while Convolutional Neural Networks (CNNs) based semantic ...
  • Positioning and timing in the MIMO-gnss framework 

    García Molina, J. A.; Fernández Rubio, Juan Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report

    This paper discusses about GNSS-based positioning and timing in challenging propagation conditions for receivers featuring an array of antennas with an arbitrary distribution. In particular, the positioning and timing ...
  • On the influence of the channel impulsional response estimation on the performance of a linear interference canceller for a DS/CDMA system 

    Díaz Romero, M. del Pilar; Agustí Comes, Ramon (Institute of Electrical and Electronics Engineers (IEEE), 1994)
    Conference report
    Open Access
    In a code division multiple access (CDMA) mobile radio communication system, interference from other users is one of the most critical drawbacks due to the lack of perfect orthogonality between user access codes. So far, ...
  • Dynamic selection and update of digital predistorter coefficients for power amplifier linearization 

    Pham, Thi Quynh Anh; López Bueno, David; Montoro López, Gabriel; Gilabert Pinal, Pere Lluís
    Conference lecture
