The hand is quicker than the eye. In many cases, so is digital
video. Maintaining image quality in bandwidth- and
memory-restricted environments is quickly becoming a reality as
thriving research delves ever deeper into perceptual coding
techniques, which discard superfluous data that humans cannot
process or detect. Surveying the topic from a Human Visual System
(HVS)-based approach, Digital Video Image Quality and Perceptual
Coding outlines the principles, metrics, and standards associated
with perceptual coding, as well as the latest techniques and
applications. This book is divided broadly into three parts. First,
it introduces the fundamental theory, concepts, principles, and
techniques underlying the field, such as the basics of compression,
HVS modeling, and coding artifacts associated with current
well-known techniques. The next section focuses on picture quality
assessment criteria; subjective and objective methods and metrics,
including vision model based digital video impairment metrics;
testing procedures; and international standards regarding image
quality. Finally, practical applications come into focus, including
digital image and video coder designs based on the HVS as well as
post-filtering, restoration, error correction, and concealment
techniques. The permeation of digital images and video throughout
the world cannot be understated. Nor can the importance of
preserving quality while using minimal storage space, and Digital
Video Image Quality and Perceptual Coding provides the tools
necessary to accomplish this goal. Instructors and lecturers
wishing to make use of this work as a textbook can download a
presentation of 786 slides in PDF format organized to augment
thetext. accompany our book (H.R. Wu and K.R. Rao, Digital Video
Image Quality and Perceptual Coding, CRC Press (ISBN:
0-8247-2777-0), Nov. 2005) for lecturers or instructor to use for
their classes if they use the book.
This book provides comprehensive coverage of the latest
trends/advances in subjective and objective quality evaluation for
traditional visual signals, such as 2D images and video, as well as
the most recent challenges for the field of multimedia quality
assessment and processing, such as mobile video and social media.
Readers will learn how to ensure the highest storage/delivery/
transmission quality of visual content (including image, video,
graphics, animation, etc.) from the server to the consumer, under
resource constraints, such as computation, bandwidth, storage
space, battery life, etc.
The book encompasses the state-of-the-art visual quality assessment
(VQA) and learning based visual quality assessment (LB-VQA) by
providing a comprehensive overview of the existing relevant
methods. It delivers the readers the basic knowledge, systematic
overview and new development of VQA. It also encompasses the
preliminary knowledge of Machine Learning (ML) to VQA tasks and
newly developed ML techniques for the purpose. Hence, firstly, it
is particularly helpful to the beginner-readers (including research
students) to enter into VQA field in general and LB-VQA one in
particular. Secondly, new development in VQA and LB-VQA
particularly are detailed in this book, which will give peer
researchers and engineers new insights in VQA.
