Continuous Wavelet Transform on the Hyperboloid [PDF]
Applied and Computational Harmonic Analysis, 2007 In this paper we build a Continuous Wavelet Transform (CWT) on the upper sheet of the 2-hyperboloid H_+^2. First, we define a class of suitable dilations on the hyperboloid through conic ptojection.

On Local Fractional Continuous Wavelet Transform [PDF]
Abstract and Applied Analysis, 2013 We introduce a new wavelet transform within the framework of the local fractional calculus. An illustrative example of local fractional wavelet transform is also presented.

The continuous wavelet transform: a primer [PDF]
, 2010 Wavelet analysis is becoming more popular in the Economics discipline. Until recently, most works have made use of tools associated with the Discrete Wavelet Transform.

Continuous and Discrete Wavelet Transforms [PDF]
SIAM Review, 1989 This paper is an expository survey of results on integral representations and discrete sum expansions of functions in $L^2 ({\bf R})$ in terms of coherent states. Two types of coherent states are considered: Weyl–Heisenberg coherent states, which arise from translations and modulations of a single function, and affine coherent states, called ’wavelets,’

THE CONTINUOUS WAVELET TRANSFORM ON CONIC SECTIONS [PDF]
International Journal of Wavelets, Multiresolution and Information Processing, 2008 We review the coherent state (or group-theoretical) construction of the continuous wavelet transform (CWT) on the two-sphere. Next, we describe the construction of a CWT on the upper sheet of a two-sheeted hyperboloid, emphasizing the similarities between the two cases.

Time-frequency analysis of HD 174936 and HD 174966 using the synchrosqueezed wavelet transform
Frontiers in Astronomy and Space Sciences, 2022 δ Scuti stars are intermediate-mass pulsators located in the classical Cepheid instability strip with spectral types ranging from A to F. In the last years, some authors found an amplitude and frequency modulation in some of these stars.

Fringe pattern analysis using a one-dimensional modified Morlet continuous wavelet transform [PDF]
, 2008 This paper proposes the use of a modified Morlet wavelet in order to demodulate fringe patterns in conjunction with the one-dimensional continuous wavelet transform (1D-CWT). Our investigations demonstrate that the modified Morlet wavelet produces better

On continuous wavelet transforms of distributions
Applied Mathematics Letters, 2011 Fix a spherically symmetric wavelet \(\psi\) satisfying an admissibility condition and, as usual, for any \(b\in\mathbb R^n\) and \(a>0\), denote \(\psi^{a,b}(x) = a^{-n/2}\psi(\frac{x-b}{a})\). The continuous wavelet transform of a compactly supported distribution \(f\) associated to \(\psi\) is given by \((Tf)(a,b)= \langle f,\overline{\psi^{a,b ...

Reseaech on identification of caving coal and rock traits
Gong-kuang zidonghua, 2017 In order to recognize caving coal and rock traits in fully mechanized caving face, an identification method based on continuous wavelet transform and improved singular value decomposition (SVD) was proposed.
