  • The temporal dimension of visual attention models 

    Assens Reina, Marc (Universitat Politècnica de Catalunya, 2017)
    Treball Final de Grau
    Accés obert
    This thesis explores methodologies for scanpath prediction on images using deep learning frameworks. As a preliminary step, we analyze the characteristics of the data provided by different datasets. We then explore the use ...
  • Texture-Based brain tumor segmentation in MR images 

    Rodríguez Gálvez, Borja (Universitat Politècnica de Catalunya, 2017-08-02)
    Treball Final de Grau
    Accés obert
    Realitzat a/amb:  University of California, Irvine
    In this thesis, we explored the idea of texture as a tumor segmentation approach in MR images. To deal with this, we extended the definition of the texture descriptors provided by Kovalev et al., co-occurrence matrices ...
  • Object instance segmentation using recurrent models 

    Morales Vega, Juan Carlos (Universitat Politècnica de Catalunya, 2017-06)
    Treball Final de Grau
    Accés obert
    This work intends to expand the Polygon-RNN model for object segmentation, able to create a polygon outlining an object using a CNN and a RNN, by trying several modifications. Several models and approaches have been explored. ...
  • Zero change CMOS microring modulators at 1550 nm: Modeling and characterization 

    Cea Falcó, Marc de (Universitat Politècnica de Catalunya, 2017-06)
    Treball Final de Grau
    Accés obert
    Realitzat a/amb:  Massachusetts Institute of Technology
    While optical communications are the standard solution for long haul communications, its adoption for short range (i.e, intra- and inter-chip interconnects and metro-area) transmission systems, where a considerable increase ...
  • Advanced methods of integration of GNSS and 3D models for positioning in deep urban canyons 

    Ortega González, Héctor (Universitat Politècnica de Catalunya, 2017-10)
    Treball Final de Grau
    Accés obert
    Classical GNSS positioning in urban environments presents a variety of problems such as satellite signal blockage, reflection and fading, mainly caused by buildings. These issues reduce the number of available satellites, ...
  • Training data analysis for Gaussian process state space models 

    Ferreiro Alonso, Patricia (Universitat Politècnica de Catalunya, 2017-08-31)
    Treball Final de Grau
    Accés obert
    Gaussian Process State Space Models aim at constructing models of nonlinear dynamical systems capable of quantifying the uncertainty in their predictions. By means of sampling in a noisy environment and covariance functions, ...
