A fuzzy definition of the spatial relation “surround” - Application to complex shapes

Maria Carolina Vanegas, Isabelle Bloch, Jordi Inglada
Spatial relations are of great importance for image understanding. In this paper we focus on the “surround” relation. We propose to represent the relation as a fuzzy set in the spatial domain, which considers the imprecision of the relation itself, the morphology of the reference object, and the distance...

The Uncertain Generalized Probabilistic Weighted Average and its Application in the Theory of Expertons

José M. Merigó, Montserrat Casanovas
We introduce the uncertain generalized probabilistic weighted averaging (UGPWA) operator. It is an aggregation operator that unifies the probability and the weighted average in the same formulation considering the degree of importance that each concept has in the aggregation. Moreover, it is able to...

Mobile Phone User Identification with Fuzzy Fingerprints

Nuno Homem, Joao Paulo Carvalho
Fingerprint identification is a well-known technique in forensic sciences. The basic idea of identifying a subject based on a set of features left by the subject actions or behavior can be applied to other domains. Identifying a mobile phone user based on a user fingerprint is one such application. This...

A new method of generating fuzzy implications from given ones

Sebastià Massanet, Joan Torrens
In this paper, a new construction method of a fuzzy implication from two given ones, called e-generation method, is introduced. This method allows to con- trol, up to a certain level, the increasingness on the second variable of the fuzzy implication through an adequate scaling on that variable of the...

Dependencies between fuzzy conjunctions and implications

Anna Krol
This paper deals with some dependencies between fuzzy conjunctions and fuzzy implications. More precisely, a fuzzy implication generated from a fuzzy conjunction and a fuzzy conjunction induced by a fuzzy implication is considered. In the case of a fuzzy conjunction only border conditions and monotonicity...

On lattice structure and implications on ordered fuzzy numbers

Magdalena Kacprzak, Witold Kosinski
Ordered fuzzy numbers (OFN) invented by the second author and his two coworkers in 2002 make possible to utilize the fuzzy arithmetic and to construct the Abelian group of fuzzy numbers and then an ordered ring. The definition of OFN uses the extension of the parametric representation of convex fuzzy...
