The Berkeley Wavelet Transform: A Biologically Inspired Orthogonal Wavelet Transform [PDF]
Neural Computation, 2008 We describe the Berkeley wavelet transform (BWT), a two-dimensional triadic wavelet transform. The BWT comprises four pairs of mother wavelets at four orientations. Within each pair, one wavelet has odd symmetry, and the other has even symmetry. By translation and scaling of the whole set (plus a single constant term), the wavelets form a complete ...

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

The Monogenic Wavelet Transform [PDF]
IEEE Transactions on Signal Processing, 2009 This paper extends the 1-D analytic wavelet transform to the 2-D monogenic wavelet transform. The transformation requires care in its specification to ensure suitable transform coefficients are calculated, and it is constructed so that the wavelet transform may be considered as both local and monogenic. This is consistent with defining the transform as

On the Analytic Wavelet Transform [PDF]
IEEE Transactions on Information Theory, 2010 An exact and general expression for the analytic wavelet transform of a real-valued signal is constructed, resolving the time-dependent effects of non-negligible amplitude and frequency modulation. The analytic signal is first locally represented as a modulated oscillation, demodulated by its own instantaneous frequency, and then Taylor-expanded at ...

Source identification for mobile devices, based on wavelet transforms combined with sensor imperfections [PDF]
, 2013 One of the most relevant applications of digital image forensics is to accurately identify the device used for taking a given set of images, a problem called source identification.

Wavelet shrinkage using adaptive structured sparsity constraints [PDF]
, 2015 Structured sparsity approaches have recently received much attention in the statistics, machine learning, and signal processing communities. A common strategy is to exploit or assume prior information about structural dependencies inherent in the data ...

Wavelets on the Interval and Fast Wavelet Transforms
Applied and Computational Harmonic Analysis, 1993 The paper contains a detailed analysis of several constructions of orthonormal bases of wavelets on a finite interval. A new construction is suggested which avoids some of the disadvantages of earlier constructions.

Fractional Wavelet Transform Using an Unbalanced Lifting Structure [PDF]
, 2011 In this article, we introduce the concept of fractional wavelet transform. Using a two-channel unbalanced lifting structure it is possible to decompose a given discrete-time signal x[n] sampled with period T into two sub-signals x1[n] and x2[n] whose ...
