Journal ArticleDOI
Fuzzy transforms: Theory and applications
TL;DR: A method of image compression and reconstruction on the basis of the F-transform, which is a fuzzy partition of a universe into fuzzy subsets (factors, clusters, granules etc.), is presented.
Journal ArticleDOI
An image coding/decoding method based on direct and inverse fuzzy transforms
TL;DR: The results show that the PSNR obtained with the usage of direct and inverse fuzzy transforms is higher than thePSNR determined either with fuzzy relation equations method or in the DCT one and it is close to the PS NR determined in JPEG method for small values of the compression rate.
Journal ArticleDOI
Towards a higher degree F-transform
TL;DR: The aim of this study is to show how the F-transform technique can be generalized from the cases of constant components to the case of polynomial components.
Journal ArticleDOI
Fuzzy transform in the analysis of data
TL;DR: This paper shows how fuzzy transform can be used for detection and characterization of dependencies among attributes and applies it to mining associations that have a functional character.
