Fuzzy Hough transform

Pattern Recognition Letters, 1994
To detect shapes in noisy data, the fuzzy Hough transform is introduced. This technique finds shapes by approximately fitting the data points, which avoids the spurious shapes detected when using the conventional Hough transform. An efficient implementation of this method is described for detecting lines and circles. >

Fuzzy Laplace transforms

Soft Computing, 2009
The fuzzy Laplace transform method solves fuzzy differential equations (FDEs) and corresponding fuzzy initial and boundary value problems. Fuzzy Laplace transforms reduce the problem of solving a FDE to an algebraic problem. This switching from operations of calculus to algebraic operations on transforms is called operational calculus, a very important

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

Approximation properties of fuzzy transforms

Fuzzy Sets and Systems, 2011
The goal of the paper is to enlarge the class of fuzzy transforms (F-transforms) by considering different types of fuzzy partitions. \ New types of F-transforms are constructed based on B-splines, Shepard kernels, Bernstein basis polynomials and Favard-Szaz-Mirakjan type operators. The approximation properties of these F-transforms are studied. A fuzzy

Fuzzy differential equations by fuzzy-transform

2015 Annual Conference of the North American Fuzzy Information Processing Society (NAFIPS) held jointly with 2015 5th World Conference on Soft Computing (WConSC), 2015
The fuzzy transform setting (F-transform), as a tool for general continuous approximation of functions, is proposed to approximate the solution of ordinary, interval or fuzzy (levelwise) differential equations; in particular, one of the basic properties of inverse F-transform allows a good approximation of the solution x(t), starting with the uniform ...

Fuzzy transformations and fuzzy residuated connections

Journal of Intelligent & Fuzzy Systems, 2019
In this paper, we define residuated connections and Galois connections and investigate their properties in a Zhang’s fuzzy complete lattice sense. In fact, the relation between fuzzy transform and inverse fuzzy transform is a residuated connection. Using the properties of residuated connections we can solve fuzzy relation equations of fuzzy transform ...
