算术编码是把一个信源表示为实轴上0和1之间的一个区间

Program 1: "lbg.cpp" is used to cluster data and the codebook can be obtain
           by using this algorithm.
           
           lbg <input picture file>  <input codebook size>  <output codebook file>

           Example:
                            lbg text 512 lena.bok

           The example of "text" file:
                            2 lena plane

Program 2.1: "e_vq.cpp" is a full searching VQ.

           e_vq <input picture file> <input codebook file> <output code file>

           Example:
                            e_vq lena lena.bok code

Program 2.2: "d_vq.cpp" is a decoding program.

           d_vq <input picture file> <input codebook file> <input code file> <output picture file>

           Example:
                            d_vq lena lena.bok code ttt

Program 3.1: "e_smvq.cpp" is a full searching VQ.

           e_smvq <input picture file> <input codebook file> <output code file> <side-match num>

           Example:
                            e_smvq lena lena.bok code  128

Program 3.2: "d_smvq.cpp" is a decoding program.

           d_smvq <input picture file> <input codebook file> <input code file> <output picture file> <side-match num>

           Example:
                            d_smvq lena lena.bok code ttt  128

Program 4.1: "e_gmvq.cpp" is a full searching VQ.

           e_gmvq <input picture file> <input codebook file> <output code file> <side-match num>

           Example:
                            e_gmvq lena lena.bok code  128

Program 4.2: "d_gmvq.cpp" is a decoding program.

           d_gmvq <input picture file> <input codebook file> <input code file> <output picture file> <side-match num>

           Example:
                            d_gmvq lena lena.bok code ttt  128
