Detailed Description

A general class for coding and decoding wavelet subband data using variable length coding,

Constructor & Destructor Documentation

dirac::BandVLC::BandVLC ( SubbandByteIO subband_byteio,
const SubbandList band_list,
int  band_num,
const bool  is_intra 
)

Creates a BandVLC object to encode subband data

Parameters:
subband_byteio input/output for the encoded bits
band_list the set of all the subbands
band_num the number of the subband being coded
is_intra Flag indicating whether the band comes from an intra picture
