     XXI Brazilian Symposium on Computer Graphics and Image Processing
                 Campo Grande, Mato Grosso do Sul, Brazil

-------------------------------------------------------------------------------

The Brazilian Symposium on Computer Graphics and Image Processing,
SIBGRAPI 2008, will be held on October 12-15, 2008, in Campo Grande,
Mato Grosso do Sul state. Campo Grande is well known for its
ecotourism and home of the Brazilian Pantanal.

SIBGRAPI is the most important Brazilian meeting in Computer
Graphics, Image Processing, and Computer Vision. Started in 1988 with the
sponsorship of the Brazilian Computer Society, this will be its 21th
edition. IEEE CS Press has published the proceedings of SIBGRAPI since
1997. All full papers are blindly reviewed by three experts in the topic
of the work and the acceptance rate is about 30% of the submitted papers.

We have the pleasure to announce the following invited speakers:

** Dr. Jos Stam
Senior scientist at Autodesk Inc. Stam's research spans several areas
of computer graphics: natural phenomena, physics-based simulation,
rendering and surface modeling, specially subdivision surfaces. He has
published papers in all of these areas in journals and at conferences,
most notably at the annual SIGGRAPH conference. In 2005 Stam was
awarded one of the most prestigeous awards in computer graphics: the
SIGGRAPH Computer Graphics Achievement Award. And for the impact his
work on subdivision surface has had on the movie industry, he was
awarded the 2005 Technical Achievement Award (Academy certificate)
from the Academy of Motion Picture Arts and Sciences.  http://www.josstam.com

** Prof. James L. Crowley
Directs the PRIMA Research Project group at the INRIA Rhone-Alpes
research center in Montbonnot (near Grenoble), France. He holds the
post of Professor at the Institut National Polytechnique de Grenoble
(INPG), where he teaches courses in Computer Vision, Signal
Processing, Pattern Recognition and Artificial Intelligence at
l'ENSIMAG (Ecole National Superieure d'Informatique et de
Mathematiques Appliquées). From 2003 through 2006, Professor Crowley
has served as director for the UMR GRAVIR laboratory (UMR 5527 CNRS,
INPG, UJF, INRIA) Professor Crowley has edited two books, five special
issues of journals, and authored over 180 articles on computer vision
and mobile robotics.  Personal Website: http://www-prima.imag.fr/Prima/Homepages/jlc/jlc.html


** Prof. Nelson D. A. Mascarenhas
Associate professor at Universidade Federal de São Carlos, Department
of Computing, where he teaches graduate courses in Digital Signal
Processing, Probability and Discrete Stochastic Processes and Special
Topics in Image Processing and Recognition, among others. He has been
an active researcher in Computer Sciences and Electrical Engineering,
and his main research interests are focused on Digital Image
Processing and Pattern Recognition.  Personal Website: http://www.dc.ufscar.br/~nelson/


**Prof. William K. Pratt
William Pratt is a pioneer in digital image processing. He is
responsible for the discovery of the transform image coding concept,
which is the basis for the JPEG and MPEG image coding standards. He is
the inventor of a facsimile coding system and a means of high-speed
image convolution, as well as the document editor of the Programmer's
Imaging Kernel System (PIKS) application program interface
standard. Pratt is the author of Laser Communications, Digital Image
Processing, PIKS Foundation C Programmer's Guide and XIL: An Imaging
Foundation Library.
