Download or read book Digital Video Image Quality and Perceptual Coding written by H.R. Wu and published by CRC Press. This book was released on 2017-12-19 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Television and the Quality of Life written by Robert Kubey and published by Routledge. This book was released on 2013-12-02 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Employing a unique research methodology that enables people to report on their normal activities as they occur, the authors examine how people actually use and experience television -- and how television viewing both contributes to and detracts from the quality of everyday life. Studied within the natural context of everyday living, and drawing comparisons between television viewing and a variety of other daily activities and leisure pursuits, this unusual book explores whether television is a boon or a detriment to family life; how people feel and think before, during, and after television viewing; what causes television habits to develop; and what causes heavy viewing -- and what heavy viewing causes -- in the short and long term. Television and the Quality of Life also compares the viewing experience cross-nationally using samples from the United States, Italy, Canada, and Germany -- and then interprets the findings within a broad theoretical and historical framework that considers how information use and daily activity contribute to individual, familial, societal, and cultural development.

Download or read book Image Quality Enhancement written by Robert W. Brainard and published by . This book was released on 1964 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique for enhancing the quality of imagery was investigated. The technique consists of obtaining a video signal from a transparency and adding to this signal its first and/or second derivative(s). The efficacy of the technique was evaluated by comparing imagery produced by the video signal and its derivative(s) with imagery produced by the video signal alone. The imagery investigated consisted of standard test patterns and aerial photographs. The processed test patterns were quantitatively analyzed to determine the resolution, contrast and acutance of the imagery. The results indicate: (1) differentiation enhances image quality, as indicated by the resolution, contrast and acutance metrics, (2) greatest enhancement is produced by operations which include second-order differentiation, and (3) the least enhancement is produced by first-order differentiation. The aerial photographic imagery shows the same enhancing effects as those obtained with the test patterns. (Author).

Download or read book Flat Panel Displays and CRTs written by Lawrence E. Tannas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flat-Panel Displays and CRTs, a review of electronic information display devices, is the first sys tematic and comprehensive coverage of the subject. It is intended to distill our wealth of knowledge of flat-panel displays and CRTs from their beginnings to the present state of the art. Historical perspective, theory of operation, and specific applications are all thoroughly covered. The field of display engineering is a multidisciplined technical pursuit with the result that its individual disciplines suffer from a lack of communications and limited perspective. Many previ ously developed standards for, and general understanding of, one technology are often inappro priate for another. Care has been taken here to document the old, incorporate the new, and emphasize commonalities. Criteria for performance have been standardized to enable an expert in one display technology, such as liquid crystals, to compare his device performance with that offered by another technology, such as electroluminescence. This book has been written with a second purpose in mind, to wit, to be the vehicle by means of which a new scientist or engineer can be introduced into the display society. It is organized to be tutorial for use in instructional situations. The first chapters begin with first principles and defini tions; the middle chapters set out requirements and criteria; and the last chapters give a complete description of each major technology.
