.SH NAME
QccWAVSubbandPyramid3DIntDWT, QccWAVSubbandPyramid3DIntInverseDWT \- 
separable 3D discrete wavelet transform and inverse transform
for integer-valued subband-pyramid data
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVSubbandPyramid3DIntDWT(QccWAVSubbandPyramid3DInt *" subband_pyramid ", int " transform_type ", int " temporal_num_levels ", int " spatial_num_levels ", const QccWAVWavelet *" wavelet );
.br
.BI "int QccWAVSubbandPyramid3DIntInverseDWT(QccWAVSubbandPyramid3DInt *" subband_pyramid ", const QccWAVWavelet *" wavelet );
.SH DESCRIPTION
.B QccWAVSubbandPyramid3DIntDWT()
performs a separable 3D discrete wavelet transform (DWT) on the
.I volume
field of
.IR subband_pyramid .
.IR transform_type
determines whether the transform is a dyadic or wavelet-packet
decomposition. For a dyadic decomposition,
.IR transform_type
should be
.BR QCCWAVSUBBANDPYRAMID3DINT_DYADIC ;
for a wavelet-packet decomposition,
.IR transform_type
should be
.BR QCCWAVSUBBANDPYRAMID3DINT_PACKET .
.B QccWAVSubbandPyramid3DIntDWT()
implements the wavelet transform with a call to
.BR QccWAVWaveletDyadicDWT3DInt (3)
or
.BR QccWAVWaveletPacketDWT3DInt (3)
as appropriate.
.LP
If a dyadic decomposition is chosen
.RI ( transform_type
equal to
.BR QCCWAVSUBBANDPYRAMID3DINT_DYADIC ),
.I spatial_num_levels
and
.I temporal_num_levels
must be set to the same value which indicates
the number of levels (scales) of dyadic decomposition to perform.
In this case, both the 
.I spatial_num_levels
and
.I temporal_num_levels
fields of
.I subband_pyramid
are set to this value.
Alternatively, if a wavelet-packet decomposition is chosen
.RI ( transform_type
equal to
.BR QCCWAVSUBBANDPYRAMID3DINT_PACKET ),
then
.I spatial_num_levels
and
.I temporal_num_levels
may be different and indicate the number of spatial decompositions and
temporal decompositions, respectively, performed when
calculating the wavelet-packet transform.
.LP
The
.IR origin_frame ,
.IR origin_row ,
.IR origin_col ,
.IR subsample_pattern_frame ,
.IR subsample_pattern_row ,
and
.IR subsample_pattern_col
parameters as needed for
.BR QccWAVWaveletDyadicDWT3DInt (3)
or
.BR QccWAVWaveletPacketDWT3DInt (3)
are extracted from the corresponding fields of
.IR subband_pyramid .
.LP
.BR QccWAVSubbandPyramid3DIntInverseDWT()
calls
.BR QccWAVWaveletInverseDyadicDWT3DInt (3)
or
.BR QccWAVWaveletInversePacketDWT3DInt (3)
to perform a separable 3D inverse DWT on the
.I volume
field of
.IR subband_pyramid .
The
.IR transform_type
field of
.IR subband_pyramid 
indicates the type (dyadic or wavelet-packet) of transform,
while the numbers of levels of the inverse transform is retrieved from the
.I spatial_num_levels
and
.I temporal_num_levels
fields of
.IR subband_pyramid .
Both
.I spatial_num_levels
and
.I temporal_num_levels
are set to 0 upon return of
.BR QccWAVSubbandPyramid3DIntInverseDWT().
.SH "RETURN VALUES"
These routines
return 0 on success and 1 on error.
