After reviewing this recently developed theory, we examine the use of multiwavelets in a filter bank setting for discrete-time sig- nal and image processing.
TFR offer the time localization vs. frequency localization tradeoff between two extreme cases of time-domain and frequency-domain representations. The short- ...
This example shows how to perform and interpret the time-frequency analysis of signals obtained with the continuous wavelet transform (CWT).
As examples, we present some time-varying wavelet convolutional codes ... We also prove that orthogonal filterbanks generate self-dual time-varying codes.
In electrical engineering language the filter bank representing wavelet transforms is a constant Q filter bank, or an octave band filter bank. The ...
Analysis of M-channel time-varying filter banks. In this paper we present a new theory to analyze M-channel time-varying filter banks in the transform-domain.
In this work, a general multi-objective optimized wavelet filter is proposed to adaptively extract the bearing fault features.
