indwt2

Inverse nondecimated 2-D wavelet transform

Calling Sequence

C=indwt2(W,type,[N])

Parameters

W:

ndwt structure

type :

type ('a' for low-pass components or 'd' for high-pass components)

N:

Level of decomposition

C:

reconstructed components at level N

Description

indwt performs a multilevel nondecimate reconstruction.

Examples

x=rand(2,100);
W1 = ndwt2(x,3,'db1');
a0 = indwt2(W1,'a',0);

//reconstruction error
err = max(abs(x(:)-a0(:)))
