Summary
-------
 
With regards to my earlier request for source code and references on DCT
related stuff, I would like to thank all the contributors.
 
 
Probably the most significant source for DCT code would be the JPEG source
code available from ftp.uu.net in the directory graphics/jpeg.   In the FAQ
list for comp.compression, a site avahi.inria.fr, directory /pub/h261,
contains a software implementation of the H.261 codec.
 
 
With regards to references, Tom Lane (Tom_Lane@G.GP.CS.CMU.EDU) provides a
very comprehensive list:

Tom Lane also highlights the Loeffler paper as one with the best algorithm.
 
 
Peter Freed (pfreed@rp.CSIRO.AU) also recommends a book:
 
        "Signal Processing with Lapped Transforms"
                by Henrique S Malvar(Artech House 1992)
 
and an article:
 
        Narasimha M.J. & A.M. Peterson "On the Computation of the
        Discrete Cosine Transform", IEEE Trans Commun., vol COMM 25, Sep
        1977, pp 1004-1009
 
featuring DCT stuff.
 
 
F Dudbridge (eesfd@gdr.bath.ac.uk) indicated that his colleagues B.Sherlock 
& D.Monro are also working on DCT algorithms.
 
 
I hope I did not miss out any important references.... drop me an email should 
anyone has more to add ...
has more to add...
 
Thanks again.......
