FWT_PO

Forward Wavelet Transform (periodized, orthogonal)

Calling Sequence

wc = FWT_PO(x,L,qmf)

Parameters

Inputs:

x :

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

L :

Coarsest Level of V_0; L << J

qmf :

quadrature mirror filter (orthonormal)

Outputs:

wc :

1-d wavelet transform of x.

Description

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