Legendre wavelets technique for special Initial-Value problem for the quarter plain of heat transfer [PDF]

Mathematics and Computational Sciences, 2020
In this paper we have solved the heat transfer equation by means of the Volterra integral equation and Legendre Wavelets. Since, due to numerical facts, solution of the related partial differential equation is difficult, thus we have applied integral ...

Exact reconstruction with directional wavelets on the sphere [PDF]

, 2007
A new formalism is derived for the analysis and exact reconstruction of band-limited signals on the sphere with directional wavelets. It represents an evolution of the wavelet formalism developed by Antoine & Vandergheynst (1999) and Wiaux et al. (2005).

Design and Implementation of New Biorthogonal Wavelets and its Application to Image Processing

International Journal of Emerging Research in Engineering, Science, and Management, 2022
Wavelet transformation has been an interesting field since its exposure with wavelet-based compression standard embedded zerotree wavelet. Though, the origin of wavelets back to many decades, the presence of research at the very beginning of wavelet ...

Watermarking for multimedia security using complex wavelets [PDF]

, 2010
This paper investigates the application of complex wavelet transforms to the field of digital data hiding. Complex wavelets offer improved directional selectivity and shift invariance over their discretely sampled counterparts allowing for better ...

Fourier–Boas-Like Wavelets and Their Vanishing Moments

Journal of Mathematics, 2021
In this paper, we propose Fourier–Boas-Like wavelets and obtain sufficient conditions for their higher vanishing moments. A sufficient condition is given to obtain moment formula for such wavelets. Some properties of Fourier–Boas-Like wavelets associated

Some results on generalization $\alpha-$Chebyshev wavelets [PDF]

Journal of Mahani Mathematical Research
In this paper, we introduce  generalized formulae for well-known functions such as $\alpha$-Chebyshev functions. We define $\alpha-$Chebyshev wavelets approximation and  generalization $\alpha-$wavelet coapproximation.

A Note on Some New Generalized Wavelets

Journal of Mathematics, 2022
In this paper, we define new real wavelets based on the Hartley kernel and Boas transforms. These wavelets have possible application in analyzing both the symmetries of an asymmetric real signal.

Complete Invariance Property with respect to Homeomorphism over Frame Multiwavelet and Super-Wavelet Spaces

Journal of Mathematics, 2014
We discuss the complete invariance property with respect to homeomorphism (CIPH) over various sets of wavelets containing all orthonormal multiwavelets, all tight frame multiwavelets, all super-wavelets of length n, and all normalized tight super frame ...

Epileptic seizures detection based on some new Laguerre polynomial wavelets, artificial neural networks and support vector machines

Informatics in Medicine Unlocked, 2019
Electroencephalography (EEG) is noninvasive and it is an effective tool to understand the complex nature of the brain. Its analysis by visual inspection is tedious and costly, and that is why many researchers in recent years resort to the use of computer-
