Sinossi

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.

Dalla quarta di copertina

This book addresses the issue of human visual system (HVS)-based perceptual quantitative quality metrics for digitally coded image and video as well as the issue of perceptual image and video coding. Introducing basic techniques, the text presents standard and popular coding structures, gives a classification and analysis of various coding artifacts, and provides performance measures. It further discusses subjective assessment methods, quantitative quality metrics, and test criteria. There is additional coverage on HVS-based digital image and video coder designs. The authors also highlight challenges facing future research. Instructors wishing to use this work as a textbook can download a presentation of 786 slides in PDF format.
