.SH NAME
QccWAVSubbandPyramid3DIntPacketToDyadic,
QccWAVSubbandPyramid3DIntDyadicToPacket \- 
reorganize integer-valued subband-pyramid DWT coefficients
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVSubbandPyramid3DIntPacketToDyadic(QccWAVSubbandPyramid3DInt *" subband_pyramid ", int " num_levels );
.br
.BI "int QccWAVSubbandPyramid3DIntDyadicToPacket(QccWAVSubbandPyramid3DInt *" subband_pyramid ", int " temporal_num_levels ", int " spatial_num_levels );
.SH DESCRIPTION
.B QccWAVSubbandPyramid3DIntPacketToDyadic()
uses a series of inverse Lazy wavelet transforms followed by
a series of forward Lazy wavelet transforms to reorganize the coefficients
of a wavelet-packet subband pyramid into a dyadic structure.
The resulting dyadic arrangement is not a "true" dyadic decomposition,
but rather is the wavelet-packet coefficients organized in a structure
that resembles the dyadic subband-pyramid structure.
.IR num_levels
indicates the number of levels of dyadic decomposition that the
resulting dyadic organization will have.
.LP
.B QccWAVSubbandPyramid3DIntDyadicToPacket()
does the opposite operation; that is, 
.B QccWAVSubbandPyramid3DIntDyadicToPacket()
reorganizes a dyadic subband pyramid to resemble the wavelet-packet
subband-pyramid structure. 
In this case,
.IR temporal_num_levels
and
.IR spatial_num_levels
indicates the number of levels of temporal and spatial
decomposition, respectively, that the
resulting wavelet-packet organization will have.
.SH "RETURN VALUES"
These routines
return 0 on success and 1 on error.
