Fuzzy Transform for Fuzzy Fredholm Integral Equation

2021
This work pursues two goals: to solve a fuzzy Fredholm integral equation of the second kind and to propose a new numerical method inspired by the theory of fuzzy (F-) transforms. This approach allows us to transform the fuzzy Fredholm integral equation into a system of algebraic equations. The solution to this algebraic system determines an approximate

Fuzzy transform for fractional fuzzy differential equations

2022
In this research, we apply a very powerful and relatively simple technique called Fuzzy ( F) transform to solve fractional fuzzy problem with respect to fuzzy valued functions. This approach allows to transform a fractional fuzzy differential equations to the system of algebraic equations.

Fuzzy Color Image Transform

Advanced Science and Technology Letters, 2015
This paper studies a new color image edge detection method. The fuzzy inference engine is designed to detect edges. Some membership functions in horizontal and vertical directions are used for edge detecting. Experimental results show the presented method provides good performance when it is compared with conventional methods.

Fuzzy partitions and transformations

Proceedings of 1994 IEEE 3rd International Fuzzy Systems Conference, 2002
This paper is devoted to an interpretation of fuzzy sets on the basis of indistinguishability. Here we restrict to indistinguishability induced by tolerance bounds /spl epsiv/ that lead to identifying numbers whose difference is less than /spl epsiv/. We admit the modification of the ordinary distance by scaling functions.

Fuzzy transforms: Theory and applications

Fuzzy Sets and Systems, 2006
In this paper the technique of the direct and inverse fuzzy transform is introduced and approximation properties of the inverse fuzzy transform are established. Two new fuzzy transforms based on operations of a residuated lattice on \([0,1]\) are introduced. These new lattice fuzzy transforms lead to new approximation models. Three types of the inverse

Fuzzy Set Transformation and Fuzzy Arithmetic

2020
The chapter elaborates on the ways of transforming fuzzy sets through functions: one of the fundamental concepts of processing fuzzy sets. The extension principle is discussed in detail. Two key ways of mapping fuzzy sets are discussed: the one based on the representation theorem (which directly links to the mapping realized in interval analysis) and ...

Spaces with fuzzy partitions and fuzzy transform

Soft Computing, 2017
\par The paper considers a categorical approach to the setting of \(F\)-transforms of \textit{I. Perfilieva} [Fuzzy Sets Syst. 157, No. 8, 993--1023 (2006; Zbl 1092.41022)] from approximation theory. The author builds his machinery over an integral commutative quantale \(Q=(Q,\bigvee, \otimes, 1_Q)\) (see, e.g., [\textit{P.

On Fuzzy Fractal Transforms

2012
Approximation of an image, a union of spatially—contracted and grayscale modified copies of subsets of itself is known as fractal image coding. Generally, images are considered as function u(x) in \( L^{2} \) or \( L^{\infty } , \) and fractal coding method is developed.
