wp2wtree
Extract wavelet tree from wavelet packet tree
Syntax
T = wp2wtree(
T
)
Description
wp2wtree
is a one- or
two-dimensional wavelet packet analysis function.
T = wp2wtree(
computes
the modified wavelet packet tree T
)T
corresponding
to the wavelet decomposition tree.
Examples
% The current extension mode is zero-padding (see dwtmode
).
% Load signal.
load noisdopp; x = noisdopp;
% Decompose x at depth 3 with db1 wavelet packets
% using shannon entropy.
wpt = wpdec(x,3,'db1');
% Plot wavelet packet tree wpt.
plot(wpt)
% Compute wavelet tree. wt = wp2wtree(wpt); % Plot wavelet tree wt. plot(wt)
