.SH NAME
QccWAVWaveletAnalysis3D, QccWAVWaveletSynthesis3D \- 
separable wavelet analysis/synthesis of a 3D signal
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVWaveletAnalysis3D(QccVolume " volume ", int " num_frames ", int " num_rows ", int " num_cols ", int " phase_frame ", int " phase_row ", int " phase_col ", const QccWAVWavelet *" wavelet );
.sp
.BI "int QccWAVWaveletSynthesis3D(QccVolume " volume ", int " num_frames ", int " num_rows ", int " num_cols ", int " phase_frame ", int " phase_row ", int " phase_col ", const QccWAVWavelet *" wavelet );
.SH DESCRIPTION
.B QccWAVWaveletAnalysis3D()
performs one level of a separable 3D wavelet decomposition for
a three-dimensional signal,
.IR volume ,
which is represented as a volume of
.IR num_frames
frames,
.I num_rows
rows, and
.I num_cols
columns.
Essentially,
.BR QccWAVWaveletAnalysis3D()
calls
.BR QccWAVWaveletAnalysis2D (3)
once for each frame of the volume, and then
.BR QccWAVWaveletAnalysis1D (3)
for each vector in the temporal direction.
.IR phase_frame ,
.IR phase_row ,
and
.I phase_col
indicate whether the frames, rows, and columns, respectively, of the image
start with even- or odd-indexed samples.
Usually, one assumes that the upper corner of the image cube is
indexed as (0, 0, 0) - in this case, 
.IR phase_frame ,
.IR phase_row ,
and
.I phase_col
would all be
.BR QCCWAVWAVELET_PHASE_EVEN .
In any event,
.IR phase_frame ,
.IR phase_row ,
and
.IR phase_col
are passed 
with each call to 
.BR QccWAVWaveletAnalysis2D (3)
and
.BR QccWAVWaveletAnalysis1D (3)
as appropriate.
The result of the separable decomposition is returned in
.IR volume .
.LP
.B QccWAVWaveletSynthesis3D()
performs one level of separable wavelet synthesis
for a 3D signal.
Subbands in 
.I volume
are assumed to be organized as described above for the output of
.BR QccWAVWaveletAnalysis3D() .
.B QccWAVWaveletSynthesis3D()
calls
.BR QccWAVWaveletSynthesis1D (3)
once for each vector in the temporal direction, then
.BR QccWAVWaveletSynthesis2D (3)
for each frame.
The result of the separable wavelet synthesis is returned in
.IR volume .
.LP
Note:
In general, you will probably want to use
.BR QccWAVWaveletDyadicDWT3D (3)
and
.BR QccWAVWaveletInverseDyadicDWT3D (3),
or
.BR QccWAVWaveletPacketDWT3D (3)
and
.BR QccWAVWaveletInversePacketDWT3D (3),
for implementing a discrete wavelet transform and its inverse since
these routines
allow any number of scales, or levels, of decomposition to be
performed.
.SH "RETURN VALUES"
These routines
return 0 on success and 1 on error.
