cplxdual2D

Complex 2D dualtree wavelet transform

Calling Sequence

[c1,c2,s]=cplxdual2D(x,J,Faf,af)

Parameters

x
: input matrix
J
: decomposition level
Faf
: first stage analysis filter
af
: further stage analysis filter
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
: coefficient size matrix

Description

cplxdual2D is an utility function of 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);
