Preface
major areas covered include intensity transformations, linear and nonlinear spatial fil-
tering, filtering in the frequency domain, image restoration and registration, color
image processing, wavelets image data compression, morphological image processing,
image segmentation, region and boundary representation and description, and object
recognition. This material is complemented by numerous illustrations of how to solve
image processing problems using
MATLAB and
IPT
functions. In cases where a func-
tion did not exist, a new function was written and documented as part of the instruc-
tional focus of the book. Over 60 new functions are included in the following chapters.
These functions increase the scope of
IPT by approximately 35 percent and also serve
the important purpose of further illustrating how to implement new image processing
software solutions.
The material is presented in textbook
format, not as a software manual. Although
the book is self-contained, we have established a companion Web site (see Section 1.5)
designed to provide support in a number of areas. For students following a formal
course of
studv or individuals embarked on a program of self study, the site contains
tutorials and reviews on background material, as well as projects and image databases,
including all images in the book. For instructors, the site contains classroom presenta-
tion materials that include
Powerpoint slides of all the images and graphics used in the
book. Individuals already familiar with image processing and
IIT fundamentals will
find the site a useful place for up-to-date references, new implementation techniques,
and a host of other support material not easily found elsewhere. All purchasers of the
book are eligible to download executable files of all the new functions developed in
the text.
As is true of most writing efforts of this nature, progress continues after work on the
manuscript stops. For this reason, we devoted significant effort to the selection of ma-
terial that we believe is Fundamental, and whose value is likely to remain applicable in
a rapidly evolving body of knowledge. We trust that readers of the book will benefit
from this effort and thus
find the material timely and useful in their work.

We are indebted to a number of individuals in academic circles as well as in industry
and
government who have contributed to the preparation of the book.Their contribu-
tions have been important in so many different ways that we find it difficult to ac-
knowledge them in any other way but alphabetically. We wish to extend our

C.
Gonzalez received the B.S.E.E. degree from the University of Miami in 1965
and the M.E. and Ph.D. degrees in electrical engineering from the University of
Florida. Gainesville, in 1967 and 1970, respectively. He joined the Electrical and
Computer Engineering Department at the University of Tennessee, Knoxville
(UTK) in 1970, where he became Associate Professor in 1973, Professor in 1978.
and Distinguished Service Professor in 1984. He served as Chairman of the de-
partment from 1994 through 1997'. He is currently a Professor Emeritus of Electri-
cal and Computer Engineering at UTK.
He is the founder of the Imagt:
&
Pattern Analysis Laboratory and the Robot-
ics
&
Computer Vision Laboratory at the University of Tennessee. He also found-
ed
Perceptics Corporation in 1982 and was its president until 1992. The last three
years of this period were spent
under a full-time employment contract with West-
inghouse Corporation, who acquired the company in 1989. Under his direction,
Perce~tics became highly successful in image processing, computer vision, and
laser disk storage technologies.
In its initial ten years, Perceptics introduced a se-
ries of innovative products, including: The world's first commercially-available
computer vision system for
autonlatically reading the license plate on moving ve-
hicles; a series of large-scale image processing and archiving systems used by the
U.S. Navy at six different manufacturing sites throughout the country to inspect
the rocket motors of missiles in the Trident
I1 Submarine Program; the market
leading family of imaging boards
for advanced Macintosh computers; and a line of
trillion-byte laser disk products.
He is a frequent consultant to industry and government in the areas of pattern
recognition, image processing, and machine learning. His academic honors for work
in these fields include the 1977
UTK
College of Engineering Faculty Achievement
Award; the 1978
UTK Chancellor's Research Scholar Award; the 1980 Magnavox En-
gineering Professor Award; and the 1980 M.
E.
Brooks Distinguished Professor
Award. In 1981 he became an
IBh4 Professor at the University of Tennessee and in
1984 he was named a Distinguished Service Professor there. He was awarded a Dis-
tinguished Alumnus Award by the University of Miami in 1985, the Phi Kappa Phi
Scholar Award in 1986, and the University of Tennessee's Nathan
W. Dougherty
Award for Excellence in Engineering in 1992. Honors for industrial accomplishment
include the 1987 IEEE Outstanding Engineer Award for Commercial Development
in Tennessee: the 1988 Albert Rose National Award for Excellence in Commercial
Image Processing; the 1989 B. Otto
Wheeley Award for Excellence in Technology
Transfer: the 1989 Coopers and
Lybrand Entrepreneur of the Year Award; the 1992
IEEE Region 3 Outstanding Engineer Award; and the 1993 Automated Imaging As-
sociation National Award for Technology Development.
Dr. Gonzalez is author or co-author of over 100 technical articles, two edited
books, and five textbooks in the fields of pattern recognition, image processing,
and robotics. His books are used
in over 500 universities and research institutions
throughout the world. He is listed in the prestigious Marquis
Who's Who in Amer-
ica,
Marquis

Marquis
Who's Who in the World,
and in
10 other national and international biographical citations. He is the co-holder of
