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(T) computes the modified wavelet packet tree 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)
