The paper introduces a new class of functions from [0,1]n to [0,n] called d-Choquet integrals. These functions are a generalization of the 'standard' Choquet integral obtained by replacing the difference in the definition ... -
Dealing with uncertainty: a human perception approach in image processing
Marco Detchart, Cedric (2019)
Tesis doctoral / Doktoretza tesia
Una de las maneras de abordar la comparación entre objetos es mediante el uso de la similitud (comparando sus atributos comunes) o la disimilitud (comparando sus diferencias). La similitud ha sido estudiada de maneras muy ... -

Contribución a congreso / Biltzarrerako ekarpena
Edge detection is a basic technique used as a preliminary step for, e.g., object extraction and recognition in image processing. Many of the methods for edge detection can be fit in the breakdown structure by Bezdek, ... -
Improving the performance of fuzzy rule-based classification systems based on a nonaveraging generalization of CC-integrals named C-F1F2-integrals
Lucca, Giancarlo; Pereira Dimuro, Graçaliz; Fernández Fernández, Francisco Javier ; Bustince Sola, Humberto ; Bedregal, Benjamin ; Sanz Delgado, José Antonio (IEEE, 2019)
Artículo / Artikulua
A key component of fuzzy rule-based classification systems (FRBCS) is the fuzzy reasoning method (FRM) since it infers the class predicted for new examples. A crucial stage in any FRM is the way in which the information ... -
Interval subsethood measures with respect to uncertainty for the interval-valued fuzzy setting
Pekala, Barbara; Bentkowska, Urszula; Sesma Sara, Mikel; Fernández Fernández, Francisco Javier ; Lafuente López, Julio ; Altalhi, A. H.; Knap, Maksymilian; Bustince Sola, Humberto ; Pintor Borobia, Jesús María (Atlantis Press, 2020)
Artículo / Artikulua
In this paper, the problem of measuring the degree of subsethood in the interval-valued fuzzy setting is addressed. Taking into account the widths of the intervals, two types of interval subsethood measures are proposed. ... -
