    • Computing with uncertainty truth degrees: a convolution-based degrees 

      Miguel Turullols, Laura de Upna Orcid (2017)   Tesis doctoral / Doktoretza tesia  OpenAccess
      La teoría de los conjuntos difusos puede contemplarse como un conjunto de herramientas matemáticas excepcionalmente adaptadas para trabajar con información incompleta, falta de nitidez e incertidumbre no aleatoria. De ...
    • Convolution lattices 

      Miguel Turullols, Laura de Upna Orcid; Bustince Sola, Humberto Upna Orcid; Baets, Bernard de (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      We propose two convolution operations on the set of functions between two bounded lattices and investigate the algebraic structure they constitute, in particular the lattice laws they satisfy. Each of these laws requires ...
    • Distance transformations based on ordered weighted averaging operators 

      López Molina, Carlos Upna Orcid; Miguel Turullols, Laura de Upna Orcid; Iglesias Rey, Sara Upna Orcid; Bustince Sola, Humberto Upna Orcid; Baets, Bernard de (University of Hawaii Press, 2021)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      Binary image comparison has been a study subject for a long time, often rendering in context-specific solutions that depend upon the type of visual contents in the binary images. Distance transformations have been a recurrent ...
    • Effective roughness modelling as a tool for soil moisture retrieval from C-and L-band SAR 

      Lievens, Hans; Verhoest, Niko E. C.; Keyser, E. de; Vernieuwe, Hilde; Matgen, P.; Álvarez-Mozos, Jesús Upna Orcid; Baets, Bernard de (Copernicus Publications, 2011)   Artículo / Artikulua  OpenAccess
      Soil moisture retrieval from Synthetic Aperture Radar (SAR) using state-of-the-art backscatter models is not fully operational at present, mainly due to difficulties involved in the parameterisation of soil surface ...
    • Error in radar-derived soil moisture due to roughness parameterization: an analysis based on synthetical surface profiles 

      Lievens, Hans; Vernieuwe, Hilde; Álvarez-Mozos, Jesús Upna Orcid; Baets, Bernard de; Verhoest, Niko E. C. (MDPI, 2009)   Artículo / Artikulua  OpenAccess
      In the past decades, many studies on soil moisture retrieval from SAR demonstrated a poor correlation between the top layer soil moisture content and observed backscatter coefficients, which mainly has been attributed ...
    • A historical account of types of fuzzy sets and their relationships 

      Bustince Sola, Humberto Upna Orcid; Barrenechea Tartas, Edurne Upna Orcid; Pagola Barrio, Miguel Upna Orcid; Fernández Fernández, Francisco Javier Upna Orcid; Xu, Zeshui; Bedregal, Benjamin Upna Orcid; Montero, Javier; Hagras, Hani; Herrera, Francisco; Baets, Bernard de (IEEE, 2016)   Artículo / Artikulua  OpenAccess
      In this work we review the definition and basic properties of the different types of fuzzy sets that have appeared up to now in the literature. We also analyze the relationships between them and enumerate some of the ...
    • Multiscale edge detection using first-order derivative of anisotropic Gaussian kernels 

      Wang, Gang; López Molina, Carlos Upna Orcid; Baets, Bernard de (Springer, 2019)   Artículo / Artikulua  OpenAccess
      Spatially scaled edges are ubiquitous in natural images. To better detect edges with heterogeneous widths, in this paper, we propose a multiscale edge detection method based on first-order derivative of anisotropic Gaussian ...
    • On the role of distance transformations in Baddeley's Delta Metric 

      López Molina, Carlos Upna Orcid; Iglesias Rey, Sara Upna Orcid; Bustince Sola, Humberto Upna Orcid; Baets, Bernard de (Elsevier, 2021)   Artículo / Artikulua  OpenAccess
      Comparison and similarity measurement have been a key topic in computer vision for a long time. There is, indeed, an extensive list of algorithms and measures for image or subimage comparison. The superiority or inferiority ...
    • Twofold binary image consensus for medical imaging meta-analysis 

      López Molina, Carlos Upna Orcid; Sánchez Ruiz de Gordoa, Javier Upna Orcid; Zelaya Huerta, María Victoria Upna Orcid; Baets, Bernard de (Springer, 2018)   Contribución a congreso / Biltzarrerako ekarpena  OpenAccess
      In the field of medical imaging, ground truth is often gathered from groups of experts, whose outputs are generally heterogeneous. This procedure raises questions on how to compare the results obtained by automatic algorithms ...
