Seasonal Time Series Forecasting by F¹-Fuzzy Transform. [PDF]

Sensors (Basel), 2019
We present a new seasonal forecasting method based on F1-transform (fuzzy transform of order 1) applied on weather datasets. The objective of this research is to improve the performances of the fuzzy transform-based prediction method applied to seasonal ...

Data-Driven Fuzzy Transform

IEEE Transactions on Fuzzy Systems, 2022
The Fuzzy transform is applied mainly to 1-D signals and 2-D data organized as a regular grid (e.g., 2-D images), thus, limiting its potential application to arbitrary data in terms of dimensionality and structure.

An Alternative Estimation of Market Volatility based on Fuzzy Transform [PDF]

2017 Joint 17th World Congress of International Fuzzy Systems Association and 9th International Conference on Soft Computing and Intelligent Systems (IFSA-SCIS), 2017
Realization of uncertainty of prices is captured by volatility, that is the tendency of prices to vary along a period of time. This is generally measured as standard deviation of daily returns.

Enhanced image fusion using directional contrast rules in fuzzy transform domain. [PDF]

Springerplus, 2016
In this paper a novel image fusion algorithm based on directional contrast in fuzzy transform (FTR) domain is proposed. Input images to be fused are first divided into several non-overlapping blocks.

Fuzzy Hilbert Transform of Fuzzy Functions

Mathematics
This paper studies the properties of the Fourier transform of the fuzzy function, and extends the classical Poisson integral formula on the half plane to the fuzzy case, obtaining the composition of the fuzzy set generated by a point in the complex field

Image Matching by Using Fuzzy Transforms [PDF]

Advances in Fuzzy Systems, 2013
We apply the concept of Fuzzy Transform (for short, F-transform) for improving the results of the image matching based on the Greatest Eigen Fuzzy Set (for short, GEFS) with respect to max-min composition and the Smallest Eigen Fuzzy Set (for short, SEFS)

Applications of the Fuzzy Sumudu Transform for the Solution of First Order Fuzzy Differential Equations

Entropy, 2015
In this paper, we study the classical Sumudu transform in fuzzy environment, referred to as the fuzzy Sumudu transform (FST). We also propose some results on the properties of the FST, such as linearity, preserving, fuzzy derivative, shifting and ...

A Novel Classification Algorithm Based on Multidimensional F¹ Fuzzy Transform and PCA Feature Extraction

Algorithms, 2023
The bi-dimensional F1-Transform was applied in image analysis to improve the performances of the F-transform method; however, due to its high computational complexity, the multidimensional F1-transform cannot be used in data analysis problems, especially

A Multilevel Fuzzy Transform Method for High Resolution Image Compression

Axioms, 2022
The Multilevel Fuzzy Transform technique (MF-tr) is a hierarchical image compression method based on Fuzzy Transform, which is successfully used to compress images and manage the information loss of the reconstructed image.
