FWT_CDJV

Forward Wavelet Transform (boundary-corrected)

Calling Sequence

wc = FWT_CDJV(x,L,N)

Parameters

Inputs:

y :

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

L :

Level of V_0; L << J

N :

Degree of Daubechies Filters

Description

CDJV have developed an algorithm for wavelets on the interval which preserves the orthogonality, vanishing moments, smoothness, and compact support of Daubechies wavelets on the line.

The algorithm for wavelets on the interval of CDJV involves four objects not present in the usual periodized algorithm: right edge filters, left edge filters, and pre- and post- conditioning operators.

These objects are supplied by appropriate requests to MakeCDJVFilter.

To reconstruct use CDJV_IWT.
