IWT2_PO

Inverse 2-d MRA wavelet transform (periodized, orthogonal)

Calling Sequence

x = IWT2_PO(wc,L,qmf)

Parameters

Inputs:

wc :

2-d wavelet transform [n by n array, n dyadic]

L :

coarse level

qmf :

quadrature mirror filter

Outputs:

x :

2-d signal reconstructed from wc

Description

If wc is the result of a forward 2d wavelet transform, with wc = FWT2_PO(x,L,qmf), then x = IWT2_PO(wc,L,qmf) reconstructs x exactly if qmf is a nice qmf, e.g. one made by MakeONFilter.
