Vector Quantization压缩算法

To create the programs wpt_bitalloc, type "make all".  To remove
unnecessary files, type "make clean" To change the type of data that
the programs will process, change the definition of DATATYPE in the
file wpt.h.  It is possible to use the all the files except
wpt\_bitalloc.c as a library, see the following documentation for
usage. wpt\_bitalloc.c contains only the command-line interface
routine.  For more details on usage, see README2.

PROGRAM
    wpt_bitalloc.c

COMMAND-LINE INTERFACE
    wpt_bitalloc -c codebook_list -l decomposition_level
          -d tree_dimension -r rate

DESCRIPTION
    This program is an implementation of systematic joint best-basis
    selection and optimal bit allocation for WPT's.  It should produce any
    tree from (rate zero, highest distortion) to (highest rate, zero
    distortion), where the rate is the average number of bits per sample
    and the distortion is the average mean squared error per pixel.
    Details are given in J. R. Goldschneider and E. A. Riskin, ``Optimal
    bit allocation and best-basis selection for wavelet packets and
    {TSVQ},'' submitted for publication to IEEE Transactions on Image
    Processing, 1998.
