FWT_SBS

Forward Wavelet Transform (symmetric extension, biorthogonal, symmetric)

Calling Sequence

wc = FWT_SBS(x,L,qmf,dqmf)

Parameters

Inputs:

x :

1-d signal; arbitrary length

L :

Coarsest Level of V_0; L << J

qmf :

quadrature mirror filter (symmetric)

dqmf:

quadrature mirror filter (symmetric, dual of qmf)

Outputs:

wc :

1-d wavelet transform of x.

Description

1. qmf filter may be obtained from MakePBSFilter 2. usually, length(qmf) < 2^(L+1) 3. To reconstruct use IWT_SBS
