A new approach has been proposed to design of an automatic infant cry recognition system based on the fuzzy transform (F-transform) that classifies two different kinds of cries, which come from physiological status and medical disease. Feature extraction and development of classification algorithms play an important role in the area of automatic analysis of infant cry signals. F-transform is th...

We propose to modify image inpainting technique based on F-transform for application dedicated to cartoon images. The images have typical features which are taken into consideration. These features make original algorithm ineffective, because of its isotropic nature. Proposed modification changes it to an anisotropic.

the supercapacitive behavior of polyaniline/mno2-carbon black (pani/mno2-cb), mno2-cb nanocompositesand cb was studied. mno2-cb made by the in situ direct coating method to deposit mno2 onto cb; then pani coating was coated on it. morphology of the nanocomposite was studied by x-ray diffraction (xrd), fourier transform infrared (ft-ir) spectroscopy and scanning electron microscopy (sem). the el...

In this paper, we describe a new algorithm based on the discrete wavelet transform (DWT) which uses a multithreshold decision model (MTD model) to detect acoustic and phonetic classes (based on 10ms speech signal segments). The best thresholds of the model are found by using experimental pattern classification. Then a unit level interpolation technique is combined with the MTD model to classify...

The aim of this paper is to propose a new approach to probability density function (PDF) estimation which is based on the fuzzy transform (F-transform) introduced by Perfilieva in [10]. Firstly, a smoothing filter based on the combination of the discrete direct and continuous inverse F-transform is introduced and some of the basic properties are investigated. Next, an alternative approach to PD...
