Discrete wavelet transforms in the large time-frequency analysis toolbox for MATLAB/GNU octave
ACM Transactions on Mathematical Software (TOMS), 2016•dl.acm.org
The discrete wavelet transform module is a recent addition to the Large Time-Frequency
Analysis Toolbox (LTFAT). It provides implementations of various generalizations of Mallat's
well-known algorithm (iterated filterbank) such that completely general filterbank trees, dual-
tree complex wavelet transforms, and wavelet packets can be computed. The resulting
transforms can be equivalently represented as filterbanks and analyzed as filterbank frames
using fast algorithms.
