IWT_ATrou

Inverse Dyadic Wavelet Transform

Calling Sequence

s = IWT_ATrou(dwt,L)

Parameters

Inputs:

dwt :

an n times J-L+1 matrix

L :

Coarsest Level of V_0; L << J

Outputs:

s :

original 1-d signal; length(x) = 2^J = n

Description

1. filters are obtained with MakeATrouFilter

2. usually, length(qmf) < 2^(L+1)

3. The transformed signal can be obtained by FWT_ATrou
