IMAGE AND VIDEO COMPRESSION FOR MULTIMEDIA ENGINEERING
Ouvrage 9780849334917 : IMAGE AND VIDEO COMPRESSION FOR MULTIMEDIA ENGINEERING
dvanced technologies have increased demands for visual information and
higher quality video frames, as with 3-D movies, games, and HDTV. This
taxes the available technologies and creates a gap between the huge
amount of visual data required for multimedia applications and the
still-limited hardware capabilities. Image and Video Compression for
Multimedia Engineering bridges the gap with concise, up-to-date video
and image coding information.
The tutorial provides a solid, comprehensive understanding of the
fundamentals and algorithms of coding and details all of the relevant
international coding standards. It presents recent findings on defining
methods for generating high quality video bitstreams. The authors
present new research results and cover emerging technologies.
With the growing popularity of the applications that use large amounts
of visual data, image and video coding is an active and dynamic field.
Coverage of both image and video compression in this book yields a
unique, self-contained reference, appropriate for all related
professions. Image and Video Compression for Multimedia Engineering
builds a basis for future study, research, and development.
Preface
It is well known that in the 1960s the advent of the semiconductor
computer and the space program swiftly brought the field of digital
image processing into public focus. Since then the field has experienced
rapid growth and has entered into every aspect of modern technology.
Since the early 1980s, digital image sequence processing has been an
attractive research area because an image sequence, as a collection of
images, may provide more information than a single image frame. The
increased computational complexity and memory space required for image
sequence processing are becoming more attainable. This is due to more
advanced, achievable computational capability resulting from the
continuing progress made in technologies, especially those associated
with the VLSI industry and information processing.
In addition to image and image sequence processing in the digitized
domain, facsimile trans- mission has switched from analog to digital
since the 1970s. However, the concept of high definition television
(HDTV) when proposed in the late 1970s and early 1980s continued to be
analog. This has since changed. In the U.S., the first digital system
proposal for HDTV appeared in 1990. The Advanced Television Standards
Committee (ATSC), formed by the television industry, recom- m I ended
the digital HDTV system developed jointly by the seven Grand Alliance
members as the standard, which was approved by the Federal Communication
Commission (FCC) in 1997. Today's worldwide prevailing concept of HDTV
is digital. Digital television (DTV) provides the signal that can be
used in computers. Consequently, the marriage of TV and computers has
begun. Direct broadcasting by satellite (DBS), digital video disks
(DVD), video-on-demand (VOD), video games, and other digital video
related media and services are available now, or soon will be.
As in the case of image and video transmission and storage, audio
transmission and storage through some media have changed from analog to
digital. Examples include entertainment audio on compact disks (CD) and
telephone transmission over long and medium distances. Digital TV
signals, mentioned above, provide another example since they include
audio signals. Transmission and storage of audio signals through some
other media are about to change to digital. Examples of this include
telephone transmission through local area and cable TV.
Although most signals generated from various sensors are analog in
nature, the switching from analog to digital is motivated by the
superiority of digital signal processing and transmission over their
analog counterparts. The principal advantage of the digital signal is
its robustness against various noises. Clearly, this results from the
fact that only binary digits exist in digital format and it is much
easier to distinguish one state from the other than to handle analog
signals.
Another advantage of being digital is ease of signal manipulation. In
addition to the development of a variety of digital signal processing
techniques (including image, video, and audio) and specially designed
software and hardware that may be well known, the following development
is an example of this advantage. The digitized information format, i.e.,
the bitstream, often in a compressed version, is a revolutionary change
in the video industry that enables many manipulations which are either
impossible or very complicated to execute in analog format. For
instance, video, audio, and other data can be first compressed to
separate bitstreams and then combined to form a signal bitstream, thus
providing a multimedia solution for many practical applications.
Information from different sources and to different devices can be
multiplexed and demultiplexed in terms of the bitstream Bitstream
conversion in terms of bit rate conversion, resolution conversion, and
syntax conversion becomes feasible. In digital video, content-based
coding, retrieval, and manipulation and the ability to edit video in the
compressed domain become feasible. All system-timing signals in the
digital systems can be included in the bitstream instead of being
transmitted separately as in traditional analog systems.
The digital format is well suited to the recent development of modern
telecommunication structures as exemplified by the Internet and World
Wide Web (WWW). Therefore, we can see that digital computers, consumer
electronics (including television and video games), and
telecommunications networks are combined to produce an information
revolution. By combining audio, video, and other data, multimedia
becomes an indispensable element of modern life. While the pace and the
future of this revolution cannot be predicted, one thing is certain:
this process is going to drastically change many aspects of our world in
the next several decades.
One of the enabling technologies in the information revolution is
digital data compression, since the digitization of analog signals
causes data expansion. In other words, storage and/or transmission of
digitized signals require more storage space and/or bandwidth than the
original analog signals.
The focus of this book is on image and video compression encountered in
multimedia engineering. Fundamentals, algorithms, and standards are the
three emphases of the book. It is intended to serve as a sen i or/gradu
ate- level text. Its material is sufficient for a one-semester or
one-quarter graduate course on digital image and video coding. For this
purpose, at the end of each chapter there is a section of exercises
containing problems and projects for practice, and a section of
references for further reading.
Based on this book, a short course entitled "Image and Video Compression
for Multimedia," was conducted at Nanyang Technological University,
Singapore in March and April, 1999. The response to the short course was
overwhelmingly positive.
