.SH NAME
QccWAVSubbandPyramid3DIntZeroSubband,
QccWAVSubbandPyramid3DIntSubtractMean,
QccWAVSubbandPyramid3DIntAddMean \- 
operations on integer-valued 3D subband pyramids
.SH SYNOPSIS
.B #include "libQccPack.h"
.sp
.BI "int QccWAVSubbandPyramid3DIntZeroSubband(QccWAVSubbandPyramid3DInt *" subband_pyramid ", int " subband );
.br
.BI "int QccWAVSubbandPyramid3DIntSubtractMean(QccWAVSubbandPyramid3DInt *" subband_pyramid ", int *" mean ", const QccSQScalarQuantizer *" quantizer );
.br
.BI "int QccWAVSubbandPyramid3DIntAddMean(QccWAVSubbandPyramid3DInt *" subband_pyramid ", int " mean );
.SH DESCRIPTION
.LP
.BR QccWAVSubbandPyramid3DIntZeroSubband()
sets the coefficients of the specified
.I subband
in
.I subband_pyramid
to zero.
.I subband
is the subband number of the desired subband.
.LP
.BR QccWAVSubbandPyramid3DIntSubtractMean()
calculates the mean value of the coefficients of the baseband of
.IR subband_pyramid ,
rounds the mean to the nearest integer,
and subtracts the result from the baseband coefficients.
If
.I mean
is
.RB non- NULL ,
the value subtracted from the coefficients (the integer-valued mean)
is returned as
.IR mean .
.LP
.BR QccWAVSubbandPyramid3DIntAddMean()
adds value
.I mean
to all baseband coefficients of
.IR subband_pyramid .
It is intended to implement the reverse 
operation of
.BR QccWAVSubbandPyramid3DIntSubtractMean() ,
so
.I mean
would be returned from this latter routine in most cases.
.SH "RETURN VALUE"
These routines return 0 on success, and 1 on failure.
