    • Application of the L-fuzzy concept analysis in the morphological image and signal processing 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna; Fuentes González, Ramón Upna (Springer International Publishing, 2014)   Artículo / Artikulua  OpenAccess
      In this work we are going to set up a new relationship between the L-fuzzy Concept Analysis and the Fuzzy Mathematical Morphology. Specifically we prove that the problem of finding fuzzy images or signals that remain ...
    • Concept lattices associated with interval-valued L-fuzzy contexts 

      Burusco Juandeaburre, Ana Upna; Fuentes González, Ramón Upna (Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995)   Artículo / Artikulua  OpenAccess
      In 1882 Wille published the paper titled Restructuring lattice theory: an approach based on hierarchies of concepts, where he developed a new theory called formal concept theory. In that paper he analyzes 0/1 relations ...
    • Evolution in time of L-fuzzy context sequences 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna; Bustince Sola, Humberto Upna; Jurío Munárriz, Aránzazu Upna; Sanz Delgado, José Antonio Upna (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      In this work, we consider a complete lattice L and we study L-fuzzy context sequences which represent the evolution in time of an L-fuzzy context. To carry out this study, in the first part of the paper, we consider n-ary ...
    • Fuzzy concept lattices and fuzzy relation equations in the retrieval processing of images and signals 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna; Díaz Moreno, Juan Carlos; Medina, Jesús (World Scientific, 2017)   Artículo / Artikulua  OpenAccess
      This paper considers the introduced relations between fuzzy property-oriented concept lattices and fuzzy relation equations, on the one hand, and mathematical morphology, on the other hand, in the retrieval processing ...
    • Linking mathematical morphology and L-fuzzy concepts 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna; Bustince Sola, Humberto Upna; Fuentes González, Ramón Upna; Sesma Sara, Mikel Upna (World Scientific, 2017)   Artículo / Artikulua  OpenAccess
      In this paper we study the relation between L-fuzzy morphology and L-fuzzy concepts over complete lattices. In particular, we show how the erosion and dilation operators of the former can be understood in terms of the ...
    • Multivalued contexts associated with criteria 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna (Taylor & Francis, 2018)   Artículo / Artikulua  OpenAccess
      We are interested in the study of L-fuzzy contexts taking into account different criteria. These contexts arise when we want to analyze the relationship between objects and attributes from different points of view. ...
    • New measures for comparing matrices and their application to image processing 

      Sesma Sara, Mikel Upna; Miguel Turullols, Laura de Upna; Pagola Barrio, Miguel Upna; Burusco Juandeaburre, Ana Upna; Mesiar, Radko; Bustince Sola, Humberto Upna (Elsevier, 2018)   Artículo / Artikulua
      In this work we present the class of matrix resemblance functions, i.e., functions that measure the difference between two matrices. We present two construction methods and study the properties that matrix resemblance ...
    • The study of fuzzy context sequences 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna; Fuentes González, Ramón Upna (Atlantis Press and Taylor & Francis, 2013)   Artículo / Artikulua  OpenAccess
      In some cases, the relationship between an object set X and an attribute set Y is set up by means of a fuzzy context sequence. A particular case of this situation appears when we want to study the evolution of an L-fuzzy ...
    • The use of two relations in L-fuzzy contexts 

      Alcalde, Cristina; Burusco Juandeaburre, Ana Upna; Fuentes González, Ramón Upna (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      In the analysis of relations among the elements of two sets it is usual to obtain different values depending on the point of view from which these relations are measured. The main goal of the paper is the modelization of ...
