Visual quality assessment is an interdisciplinary topic that links image/video processing, psychology and physiology. Many engineers are familiar with the image/video processing; transmission networks side of things but not with the perceptual aspects pertaining to quality. Digital Video Quality first introduces the concepts of human vision and visual quality. Based on these, specific video quality metrics are developed and their design is presented. These metrics are then evaluated and used in a number of applications, including image/video compression, transmission and watermarking. Introduces the concepts of human vision and vision quality. Presents the design and development of specific video quality metrics. Evaluates video quality metrics in the context of image/video compression, transmission and watermarking. Presents tools developed for the analysis of video quality

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.

Digital Television deals with all present-day TV transmission methods, i.e. MPEG, DVB, ATSC and ISDB-T. The DVD Video is also discussed to some extent. The discussion is focussed on dealing with these subjects in as practical a way as possible. Although mathematical formulations are used, they are in most cases only utilized to supplement the text. The book also contains chapters dealing with basic concepts such as digital modulation or transformations into the frequency domain. A major emphasis is placed on the measuring techniques used on these various digital TV signals. Practical examples and hints concerning measurement are provided. The book starts with the analog TV baseband signal and then continues with the MPEG-2 data stream, digital video, digital audio and the compression methods. After an excursion into the digital modulation methods, all the mentioned transmission methods are discussed in detail. Interspersed between these are found the chapters on the relevant measuring technique.

Social media shapes the ways in which we communicate, think about friends, and hear about news and current events. It also affects how users think of themselves, their communities, and their place in the world. This book examines the tremendous impact of social media on daily life. When the Internet became mainstream in the early 2000s, everything changed. Now that social media is fully entrenched in daily life, contemporary society has shifted again in how we communicate, behave as consumers, seek out and enjoy entertainment, and express ourselves. Every one of the new applications of social media presents us with a new way of thinking about the economy that supports technological development and communication content and offers new models that challenge us to think about the economic impact of communication in the 21st century. The Social Media Revolution examines the tremendous influence of social media on how we make meaning of our place in the world. The book emphasizes the economic impacts of how we use the Internet and World Wide Web to exchange information, enabling readers to see how social media has taken root and challenged previous media industries, laws, policies, and social practices. Each entry in this useful reference serves to document the history, impact, and criticism of every subject and shows how social media has become a primary tool of the 21st-century world—one that not only contributes to our everyday life and social practices but also affects the future of business. The coverage of topics is extremely broad, ranging from economic models and concepts relevant to social media, such as e-commerce, crowdfunding, the use of cyber currency, and the impact of freeware; to key technologies and devices like Android and Apple iOS, apps, the cloud, streaming, and smartphones and tablets; to major entrepreneurs, inventors, and subjects of social media, such as Julian Assange, Bill Gates, Steve Jobs, Marissa Mayer, Edward Snowden, Steve Wozniak, and Mark Zuckerberg.

his textbook is designed to teach a first course in Information Technology (IT) to all undergraduate students. In view of the all-pervasive nature of IT in today’s world a decision has been taken by many universities to introduce IT as a compulsory core course to all Bachelor’s degree students regardless of their specialisation. This book is intended for such a course. The approach taken in this book is to emphasize the fundamental “Science” of Information Technology rather than a cook book of skills. Skills can be learnt easily by practice with a computer and by using instructions given in simple web lessons that have been cited in the References. The book defines Information Technology as the technology that is used to acquire, store, organize, process and disseminate processed data, namely, information. The unique aspect of the book is to examine processing all types of data: numbers, text, images, audio and video data.
