- raster scanning of subband-pyramid subbands
#include "libQccPack.h"
int QccWAVSubbandPyramidRasterScan(const QccWAVSubbandPyramid *subband_pyramid,
QccVector scanned_coefficients);
int QccWAVSubbandPyramidInverseRasterScan(QccWAVSubbandPyramid
*subband_pyramid, const QccVector scanned_coefficients);
QccWAVSubbandPyramidRasterScan() performs a raster scan on each subband
in subband_pyramid, returning the scanned coefficients in scanned_coefficients.
Each subband is scanned from upper left to lower right, and the subbands
are scanned starting with the baseband and going to the highest-frequency
subbands.
QccWAVSubbandPyramidInverseRasterScan() reverses the raster-scan
process, filling subband_pyramid with the cofficients from scanned_coefficients.
For both of these routines, subband_pyramid and scanned_coefficients must
be allocated before the routines are called.
These routines
return 0 on success and 1 on error.
