FWT_ATrou

Fast Dyadic Wavelet Transform (periodized, orthogonal)

Calling Sequence

dwt = FWT_ATrou(x,L)

Parameters

Inputs:

x :

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

L :

Coarsest Level of V_0; L << J

Outputs:

dwt :

an n times J-L+1 matrix giving the wavelet transform of x at all dyadic scales.

Description

To reconstruct use IWT_ATrou
