Preprint: Compressing still and moving images with wavelets

The following preprint is now available from ftp.math.sc.edu
in the directory /pub/wavelet/papers/varia/tutorial.


COMPRESSING STILL AND MOVING IMAGES WITH WAVELETS

The wavelet transform has become a cutting-edge technology in image
compression research. This article explains what wavelets are and
provides a practical, nuts-and-bolts tutorial on wavelet-based
compression that will help readers to understand and experiment with
this important new technology.

To appear in Multimedia Systems, Vol. 2, No. 3

The tutorial directory contains two Unix compress'ed postscript files:
"tutorial.ps.Z" and "fig8.ps.Z". The text and all figures except
Figure 8 are in tutorial.ps. Depending on the speed of your printer,
this file may take several hours to print. The file fig8.ps contains
a side-by-side comparison of JPEG and two different wavelet image
coders. This file is quite large, may take several hours to print,
and may not be printable on laser printers with less than 8MB of
memory.
All times are GMT + 1 Hour
