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 ...

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 ...

Some results on generalization $\alpha-$Chebyshev wavelets [PDF]
Journal of Mahani Mathematical ResearchIn 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.

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

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 ...

On The Continuous Steering of the Scale of Tight Wavelet Frames
, 2015 In analogy with steerable wavelets, we present a general construction of adaptable tight wavelet frames, with an emphasis on scaling operations. In particular, the derived wavelets can be "dilated" by a procedure comparable to the operation of steering ...
