The use of two relations in L-fuzzy contexts
(Elsevier, 2015) Artículo / Artikulua,
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 ...
Application of the L-fuzzy concept analysis in the morphological image and signal processing
(Springer International Publishing, 2014) Artículo / Artikulua,
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 ...
Descubrimiento de conocimiento en bases de datos utilizando técnicas de morfología matemática borrosa
(Centro de Información Tecnológica, 2007) info:eu-repo/semantics/article,
En este artículo se analiza el efecto, la utilidad y la interpretación de los filtros asociados a la Morfología Matemática Borrosa en procesos de Descubrimiento de Conocimiento en Bases de Datos. En particular se estudian ...
The study of fuzzy context sequences
(Atlantis Press and Taylor & Francis, 2013) Artículo / Artikulua,
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 ...
Fuzzy morphological operators in image processing
(Universitat Politècnica de Catalunya, 2003) Artículo / Artikulua,
First of all, in this paper we propose a family of fuzzy implication operators, which the generalised Luckasiewicz´s one, and to analyse the impacts of Smets and Magrez properties on these operators. The result of this ...
Generation of fuzzy mathematical morphologies
(Universitat Politècnica de Catalunya, 2001) Artículo / Artikulua,
Fuzzy Mathematical Morphology aims to extend the binary morphological operators to grey-level images. In order to define the basic morphological operations fuzzy erosion, dilation, opening and closing, we introduce ...
On contrast intensification operators and fuzzy equality relations
(Universitat Politècnica de Catalunya, 2000) Artículo / Artikulua,
The class of contrast intensification operators is formally defined and its lattice structure studied. The effect of these operators in the referential classification derived from special kinds of fuzzy relations is also ...
Concept lattices associated with interval-valued L-fuzzy contexts
(Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995) Artículo / Artikulua,
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 ...
Overtaker binary relations on complete completely distributive lattices related to the level sets of the L-fuzzy sets
(Universitat Politècnica de Catalunya, 1994) Artículo / Artikulua,
The class of overtaker binary relations associated with the order in a lattice is defined and used to generalize the representations of L-fuzzy sets by means of level sets or fuzzy points.
On completeness and direction in fuzzy relational systems
(Universitat Politècnica de Catalunya, 1998) Artículo / Artikulua,
The concepts of bounded subset, complete subset and directed subset, which are well known in the context of partially ordered sets (X, ≤), are extended in order to become applicable, with coherence, in fuzzy relational ...
