icplxdual2D

Complex 2-D Dual-tree Wavelet Inverse Transform

Calling Sequence

x0=icplxdual2D(c1,c2,s,Fsf,sf)

Parameters

c1 :

complex decomposition coefficient, real part for one tree and imainery part for another tree

c2 :

complex decomposition coefficient, real part for one tree and imainery part for another tree

s :

decomposition size matrix

Fsf:

first stage synthesis filter

sf :

further stage synthesis filter

x0 :

reconstructed matrix

Description

icplxdual2D is an utility function of inverse complex 2D dualtree wavelet transform. Refer to Professor Ivan Selesnick's webpage at Brooklyn Polytech, NY.

Examples

[Faf,Fsf]=FSfarras('f');
[af,sf]=dualfilt1('f');
x=rand(256,256);
[c1,c2,s]=cplxdual2D(x,3,Faf,af);
x0=icplxdual2D(c1,c2,s,Fsf,sf);
