  • A variational model for P+XS image fusion
    Ballester, Coloma; Caselles, Vicente; Igual, Laura; Verdera, Joan; Rougé, Bernard (Springer, 2006)
    We propose an algorithm to increase the resolution of multispectral satellite images knowing the panchromatic image at high resolution and the spectral channels at lower resolution. Our algorithm is based on the assumption ...
  • An end-to-end framework for intima media measurement and atherosclerotic plaque detection in the carotid artery
    Gago, Lucas; Vila, M. Mar; Grau Magaña, Maria; Remeseiro, Beatriz; Igual, Laura (Elsevier, 2022)
    Background and objectives: the detection and delineation of atherosclerotic plaque are usually manually performed by medical experts on the carotid artery. Evidence suggests that this manual process is subject to errors ...
  • Automatic low baseline stereo in urban areas
    Igual, Laura; Preciozzi, Javier; Garrido, Luís; Almansa, Andrés; Caselles, Vicente; Rougé, Bernard (AIMS American Institute of Mathematical Sciences, 2007)
    In this work we propose a new automatic methodology for computing accurate digital elevation models (DEMs) in urban environments from low baseline stereo pairs that shall be available in the future from a new kind of earth ...
  • Do individuals with autoimmune disease have increased risk of subclinical carotid atherosclerosis and stiffness?
    Vila, M. Mar; Remeseiro, Beatriz; Igual, Laura; Elosua Llanos, Roberto; Ramos, Rafel; Valdivielso, Jose Manuel; Martí-Lluch, Ruth; Marrugat de la Iglesia, Jaume (Nature Research, 2021)
    To explore the role of chronic inflammation inherent to autoimmune diseases in the development of subclinical atherosclerosis and arterial stiffness, this study recruited two population-based samples of individuals with ...
  • Increased nucleus accumbens volume in first-episode psychosis
    Forns-Nadal, Mireia; Berge Baquero, Daniel; Seme, Federico; Mané Santacana, Anna; Igual, Laura; Guinart, Dani; Vilarroya, Óscar (Elsevier, 2017)
    Nucleus accumbens has been reported as a key structure in the neurobiology of schizophrenia. Studies analyzing structural abnormalities have shown conflicting results, possibly related to confounding factors. We investigated ...
  • Level lines selection with variational models for segmentation and encoding
    Ballester, Coloma; Caselles, Vicente; Igual, Laura; Garrido, Luís (Springer, 2007)
    This paper discusses the interest of the Tree of Shapes of an image as a region oriented image representation. The Tree of Shapes offers a compact and structured representation of the family of level lines of an image. ...
