Wavelet transforms are recent mathematical techniques, based on group theory and square
integrable representations, which allows one to unfold a signal, or a field, into both space …

Heart rate variability (HRV) is a reliable reflection of the many physiological factors
modulating the normal rhythm of the heart. In fact, they provide a powerful means of …

Diabetic retinopathy (DR), which is seen in approximately one-third of diabetes patients
worldwide, leads to irreversible vision loss and even blindness if not diagnosed and treated …

Wavelet Analysis and its Applications, Volume 1: An Introduction to Wavelets provides an
introductory treatise on wavelet analysis with an emphasis on spline-wavelets and time …

The limitations of commonly used separable extensions of one-dimensional transforms,
such as the Fourier and wavelet transforms, in capturing the geometry of image edges are …

In this chapter, we develop the properties of wavelet systems in terms of the underlying filter
banks associated with them. This is an expansion and elaboration of the material in Chapter …

A simple, nonrigorous, synthetic view of wavelet theory is presented for both review and
tutorial purposes. The discussion includes nonstationary signal analysis, scale versus …

Orthonormal bases of compactly supported wavelet bases correspond to subband coding
schemes with exact reconstruction in which the analysis and synthesis filters coincide. We …

The past 20 years have witnessed unprecedented progress in brain–computer interfaces
(BCIs). However, low communication rates remain key obstacles to BCI-based …

We present the lifting scheme, a simple construction of second generation wavelets; these
are wavelets that are not necessarily translates and dilates of one fixed function. Such …
