This is software for trying out the functionality of SNHC FIT as
described in M2599 v3. This software ouputs identical results as the
FIT software by Hai Tao (which is delivered with more FIT-files than
this pacage).


1. FILES INCLUDED

README            This file.
fit_format.txt    File format for FIT-files (by Hai Tao).
test1.fit         A test .fit file (by Hai Tao) that represents an
                  interpolation:
                     left-side FAPs   <-->  right-side FAPs
                     inner lip FAPs   <-->  outer lip FAPs
                  After using this FIT, the 13 FAPs in  Marco30_cut.fap
                  are expanded to 27 FAPs per frame.
Marco30.fap       A FAP-file.
Marco30_cut.mask  A mask for cutting out 13 FAPs from Marco30.fap.
Makefile          Makefile for FIT, FAP and FBF software.
ip.cc             Source for ip, the FIT interpolation program.
cut.cc            Source for cut, the FAP-cutting program.
codec.hh          A lot of defines etc. for FIT, FAP and FBF software.
fit/*             Source file for the FIT classes.
sequence/*        Source for sequences of FAPs.
		  (Classes Sequence, FAPs, FileInfo and Mask)
stream/*          Headers for bitstream classes (ibstream and obstream).
dct/*             Source for a DCT-coder class.
matrix/*          Source for matrices. Superclass to Sequence.


2. INSTALLATION

Type 'make'. The makefile is for SUN machines. You'll probably have to
edit it if you're using some other computer.


3. USAGE

To cut out 13 FAPs from Marco30.fap:
>cut Marco30_cut.mask Marco30.fap Marco30_cut.fap

To interpolate Marco30_cut.fap to 27 FAPs:
>ip <test1.fit Marco30_cut.fap Marco30_ip.fap
