In this paper, we present a method to obtain a Fuzzy Image Segmentation from the hierarchical clustering algorithm Divide and Link. The Divide and Link algorithm consists on treating a digital image as a graph, then building spanning forest thro[...]texto impreso
Gomez, D. ; Yáñez, Javier ; Guada, Carely ; Rodríguez, Juan Tinguaro ; Montero, Javier | Elservier | 2015In this paper we introduce the concept of Fuzzy Image Segmentation, providing an algorithm to build fuzzy boundaries based on the existing relations between the fuzzy boundary set problem and the (crisp) hierarchical image segmentation problem. [...]texto impreso
Rodríguez, Juan Tinguaro ; Vitoriano, Begoña ; Montero, Javier | Pergamon-Elsevier Science Ltd | 2012Risks derived from natural disasters have a deeper impact than the sole damage suffered by the affected zone and its population. Because disasters can affect geostrategic stability and international safety, developed countries invest a huge amou[...]texto impreso
Guada, Carely ; Gomez, D. ; Rodríguez, Juan Tinguaro ; Yáñez, Javier ; Montero, Javier | Springer | 2017In this paper we discuss about graph approach in image segmentation. In first place, some main image processing techniques are classified based upon the output these methods provide. Then, a fuzzy image segmentation definition is presented becau[...]texto impreso
This paper studies the meaning of fuzzy preference under the light institionistic fuzzy sets. Intuitionism is revisted and intuitionistic fuzzy prefrerence relations are defined. A linguistic interpretation of strict and weak fuzzy preference is[...]texto impreso
Vitoriano, Begoña ; Rodríguez, Juan Tinguaro ; Tirado, Gregorio ; Martín Campo, F. Javier ; Ortuño, M. T. ; Montero, Javier | Taylor & Francis | 2015Providing emergency relief to the victims of natural disasters is a hugely complex process fraught with many challenging aspects: multiple uncertainties, little reliable information, scarcity of resources, a variety of involved entities, and so [...]texto impreso

Preference semantics examine the meaning of the preference predicate, according to the way that alternatives can be understood and organized for decision making purposes. Through opposite-based semantics, preference structures can be characteriz[...]texto impreso
Beliakov, G. ; James, S. ; Gomez, D. ; Rodríguez, Juan Tinguaro ; Montero, Javier | TOTEM.COM.PL SP | 2015In this paper we develop a data-driven weight learning method for weighted quasiarithmetic means where the observed data may vary in dimension.texto impreso
Rodríguez, Juan Tinguaro ; Lopez, Victoria ; Montero, Javier ; Vitoriano, Begoña | Public University of Navarre | 2009Extraction of rules for classification and decision tasks from databases is an issue of growing importance as automated processes based on data are being required in these fields. Interpretability of rules is improved by defining classes for ind[...]texto impreso
Rodríguez, Juan Tinguaro ; Guada, C. ; Gomez, D. ; Yáñez, Javier ; Montero, Javier | Springer | 2016This paper proposes a method to evaluate hierarchical image segmentation procedures, in order to enable comparisons between different hierarchical algorithms and of these with other (non-hierarchical) segmentation techniques (as well as with edg[...]texto impreso
In this paper we revisit some classical multicriteria decision making aid models in order to stress the presence of dual concepts, which will be consistent with Bipolar Fuzzy Sets (sometimes called Atanassov's Intuitionistic Fuzzy Sets). In addi[...]texto impreso
Este artículo presenta un modelo de preferenciaaversión (P-A), el cual permite representar el proceso mediante el que un individuo racional (bajo una racionalidad de pérdidas y ganancias) ordena sus alternativas, en base a la agregación independ[...]texto impreso
Gómez, Daniel ; Rodríguez, Juan Tinguaro ; Montero, Javier ; Bustince, H. ; Barrenechea, E. | Elsevier | 2014In this paper we introduce the definition of n-dimensional overlap functions and we justify the axiomatization proposed in its definition. Basically, these functions allow to measure the degree of overlapping of several classes in a given classi[...]texto impreso
Humanitarian Non-Governmental Organisations (NGOs) play a growing role in the response to natural disasters, but despite being largely demanded, there is no available decision support system (DSS) specifically designed to address their problem. [...]
