Multiscale structure is all around us: in biological tissues, active matter, oceans, networks, and images. Identifying the multiscale features of these systems is crucial to our understanding and ...

Abstract: The objective of this paper is to present the subject of wavelets from a filter-theory perspective, which is quite familiar to electrical engineers. Such a presentation provides both ...

Filtering a signal both using FIR filters and Wavelets. We create the Morlet Wavelet. % centered time vector wavtime = -3:1/srate:3; % parameters freq = 13; % peak frequency fwhm = 0.15; % full-width ...

The wavelet section of time-frequency isn't covered in any of the tutorials. It would be nice to have a new time-frequency section tutorial that covers wavelets.

ABSTRACT: We present wavelet bases made of piecewise (low degree) polynomial functions with an (arbitrary) assigned number of vanishing moments. We study some of the properties of these wavelet bases; ...
