idualtree

1D inverse dualtree complex wavelet transform

Calling Sequence

x=idualtree(c,l,Fsf,sf)

Parameters

c
: complex decomposition coefficient
l
: coefficient length array
Fsf
: first stage synthesis filter
sf
: further stage synthesis filter
x
: reconstruction

Description

idualtree is an utility function for 1D inverse dualtree complex wavelet transform. Refer to Professor Ivan Selesnick's webpage at Brooklyn Polytech, NY.

Examples

[Faf,Fsf]=FSfarras('f');
[af,sf]=dualfilt1('f');
x=rand(1,256);
[c,l]=dualtree(x,3,Faf,af);
x0 = idualtree(c,l,Fsf,sf);
